- calculation of structure response to seismic effects. For determination of seismic load ČSN 730036 or ANSI codes can be used or arbitrary spectrum of response can be entered.

- calculation of structure response to general dynamic load using direct integration or expansion according to eigen modes

The elements library contains a series of beam and square elements (with shear influence) which makes possible to solve arbitrary truss and shell structures including their combinations, e.g. lattice structures, frames, grates, plates, walls, shell structures, etc. The program also contains a unique module for solution of subsoil and structure interaction.

The program uses a productive and considerably automated generator of finite element mesh including models of a series frequently used structure types and structure joints.

An extensive data bank and a data bank of cross sections (rolled, welded, concrete, etc.) are available. The cross section, which is not contained in the data bank, can be entered by its characteristics or by its contour. The program can determine cross section characteristics for any general cross section.

The postprocessor supports a combination of responses in individual load cases and assessment of lattice steel structures (including stability) according to various codes.

The program supports the following codes: ČSN 731401, STN, Eurocode 3, DIN 18800, ÖNORM 4300, NEN 6770 - 6771, AISC - ASD, AISC - LRFD and CM 66. Assessment of screwed and welded frame joints according to EC3 can be also performed.

A.S.I. SECTION III., ASME Code Section III. codes). It contains, among others, the following basic sub-programs:

STATESM – MONOTON - calculation and assessment of pressure vessels and bodies strength for monotone loads

STATESF – FATIGUE - assessment of pressure vessels and steel structures for fatigue in the stage of defect initiation

STATESS - STATESU - FATIGUE - assessment of screws and bolts strength for monotone load and fatigue

STATESG - calculation of defect growth in vessels and bodies, determination of critical defect size

MMDB - material databank

The program is standardized by the State Office for Nuclear Safety (SÚJB) for stress analysis of nuclear power plants equipment.

JAPAR The program, based on the finite elements method (FEM), is intended for stress analysis

of piping systems, frame structures and their combination in linear region with assessment according to RTM 108.020.01-75 (correction of older codes of INTERATOMENERGO - Russian standard for nuclear power plants) or according to NDT A.S.I. SECTION III - Czech standard for nuclear power plants.

The program enables determination of the response to all types of static loads and arbitrary boundary conditions.

The program conducts modal analysis (calculation of eigen values and eigen modes) in the area of dynamics. This is done for mono-spectral and multi-spectral seismic analysis including ZPA effect. The program has two graphics postprocessors: JAPAGRA - gives the summary of results and assessment. Sorting of pipe branches

according to safety margin in various criteria and sorting of modes according to either of output magnitudes of seismic solution.

JAR - can create drawings of pipeline system according to design custom practice.


STAPAR The program based on the finite element method (FEM) is intended for stress analysis of

pipeline systems, frame structures and their combination with emphasis on solution of lattice structures. The assessment of lattice structures is made according to ČSN 731401 and assessment of pipeline is made according to ASME B31.1.

The program can solve the same problems like JAPAR. In addition, the program can solve linear stability problem (stability eigen values and eigen modes) including unique possibilities like inclusion of tilting effect (stability with regards to bending moments) in the global model or solution of linear stability problem not only in the statics but also for individual eigen modes and combine rate of risk of stability failure (beside other magnitudes) in the spectra response method.


The program makes it further possible to perform a geometrically non-linear solution. For easier entry of certain types of imperfections the program includes the possibility of tilting the geometry by defined angle without changing the direction of loading effects including deadweight (initial imperfections simulate certain types of incorrect assembly).


MOVYKO MOVYKO is a program based on the finite element method (FEM) that can solve plane

and rotation symmetrical task, loaded by symmetric or non-symmetric loads.

Types of solved tasks: - linear static analysis - thermal and thermomechanical analysis - thermomechanical analysis of flange joints (sub-programs

SRSP01 and SRSP02) Stress assessment in defined cross sections can be subsequently made by the STATES program system.


ROSA The program performs static and dynamic structure analysis based on the finite element

method (FEM). The program has an extensive library of finite elements - e.g. 3D truss elements, 3D beam

elements, membrane elements with plane state of stress - triangular and quadrilateral, further two- dimensional finite elements - triangular or quadrilateral (distortion in a plane, plane state of stress, rotational symmetry), three-dimensional body elements made of eight nodes, three-dimensional plate and shell elements - triangular or quadrangular, edge elements, three-dimensional thick shell elements and three-dimensional elements straight or curved pipe elements.

All analyses described above are proceeded in linear range. Static analysis can be made for any force and deformation load, including load by steady

thermal field. Dynamic analysis can be used for the solution of the following tasks: - solution of eigenvalues and eigen modes (for smaller tasks the method is based on the

features of Sturm sequence, for larger problems the technique of subspace iteration is used) - steady harmonic vibration of the structure - response on any dynamic loading by expansion according to the eigen mode - response on any dynamic loading by direct integration method - response by means of spectral analysis

RONAP The program is used for evaluation of the results received from the solution of the static

and spectral seismic analysis achieved by ROSA program (components of stress, forces and moments). Further the RONAP program is used for achievement and evaluation of result combinations, received from the ROSA program.

Maximum shear stress theory is used for assessment of stresses. The combination of individual load cases can be done by means of the linear algebraic combination (including the signs), combination of absolute values or combination by SRSS method. Created


combinations of load cases represent new load cases that can be combined again. For the final combination of load case with signs and load case in absolute values all possible combinations of stress components of both cases are performed automatically and resulting equivalent stress is determined.

Each load case can be multiplied by selected factor for the calculation of arbitrary combination of load cases.

SEINV The program for calculation of horizontal and vertical seismic effects on a vertical tank

with liquid. The solution of the response on horizontal seismic excitation is made separately for “impulsive” and “convective” influences of liquid on tank vibrations, i.e. on condition of weak coupling between eigen modes of the tank and eigen modes of free liquid level.

Impulsive response is solved with taking effects of tank deformations into consideration. The response solution goes from the knowledge of eigen modes of the tank with liquid (can be determined quite exactly with exclusion of interaction problem solution). Impulsive hydrodynamic pressure is determined from the speed potential of the liquid in the tank acquired by solution of Laplace differential equation (Euler formulation) for the boundary conditions corresponding to the eigen mode of the tank. The tank responses are solved using the expansion according to eigen modes.

The solution of tank response on the convective component of the hydrodynamic pressure, i.e. on vibration of free liquid level, consist in determination of speed potential of liquid in the tank whose deformation can be neglected. The potential can be determined by solution of Laplace differential equation (Euler formulation) for given boundary conditions, corresponding to the given forced movement of ideally rigid tank and respecting the movement of free liquid level. The vibration of liquid level and hydrodynamic pressure on the tank wall are determined from the speed potential.

Resultant response of the tank on horizontal effects is determined by the superposition of “impulsive” and “convective” response.

Vertical vibration of the liquid in the tank is solved with taking elasticity of the tank wall and compressibility of the liquid into consideration. Seismic excitation of the tanks is considered in the basis (data entry by means of spectra of response). The following most important results can be achieved by the program: - horizontal frequency of the tank with liquid

(impulsive and convective); - vertical frequency of liquid in the tank; - presumable maximum hydrodynamic

pressures on the wall and bottom of the tank;

- presumable maximum internal forces along the height of the tank (on the whole cross section of the tank);

- total load of the subsoil under the tank; - load of the subsoil ring under the tank wall;

The results of the program were successfully tested both by comparing with the results of other programs (SYSTUS and ANSYS) and by means of tests on models with excitation in the basis. The program can


be used both for cylindrical and multi-cylindrical tanks.


SEINH SEINH is a program similar to SEINV program but solves horizontal and seismic effects

on vertical square (rectangular plan) tanks with liquid.

PVESS PVESS is a software for dimensioning of pressure vessels. It is intended for stress

analysis of pressure and non-pressure vessels and their parts according to following codes: - ČSN 690010 Stationary pressure vessels - AD-Merkblätter series B a S

GEONEL GEONEL is a program based on the finite element method (FEM). It is particularly a

testing and development program and its successful parts can be consequently used or included in other programs. The program is used for the analysis of lattice structures. It deals particularly with non-linearities in the statics. In dynamics it can be also used for modal analysis of mechanical systems in complex range (complex eigen values and eigen modes) and for solution of harmonic excitation of systems for non-proportional damping (contains a solver of systems of linear algebraic equations in complex arithmetic). The program is continuously developed and can be easily modified.

VN VN is a program based on the finite element method (FEM). Using beam elements it

makes possible to solve global response of tall vessels (reactors, columns, towers, etc.) with arbitrary anchorage. It solves static task, modal analysis, response on seismic excitation using the spectra response method (also according to the ČSN 690010 4.22) and problems of static and dynamic component of the response from the wind in accordance with the ČSN 690010 4.22 (can be modified according to other standards).

The conditions of transverse vibration origination are assessed according to ČSN 690010 4.23, excitation and damping are quantified according to ČSN 730035 P2.17 to P2.19. Strength checks of dangerous points are performed according to ČSN 690010 4.23. Everything can be modified according to other codes.

ROTOKAR ROTOKAR is a program for solution of the circular vibration of rotors. It uses the

solution of the system of algebraic equations and of the problem of eigen values and eigen modes in complex range for linearly lined up elements. With the exception of general tasks (critical speed and modes) the program can even discover the loss of stability (buckling).

D3D The D3D program serves for assessment of fatigue usage cumulation. The general

loading process is divided into elementary loading cycles using the rain flow method applied in an unique way also on triaxial state of stress.

Except for the above-mentioned programs we also own a series of programs for special purposes, for example:


- various pre- and post-processors for above mentioned programs (often programs for discretization of parametric, often used models); - programs for often repeated tasks - assessment of screwed joints, welds, nozzles, saddle supports of vessels, elements of apparatuses anchorage, flange joints, standardized steel structures, etc. - programs for often used standards, etc.

The programs have been mostly created by our experts. Our staff members are also authors of some of above mentioned programs (JAPAR, STAPAR, GEONEL, ROTOKAR, ROSA, RONAP, SEINV, SEINH, D3D). From the above mentioned facts it is clear that we can respond quickly to customer requirements, even in cases of necessity of new software or modification of current software.

We use also common software like Microsoft Office 2000, MathCad 12, CorelDRAW 9,

Exceed v.7.1, Exceed 3D v.7.1 etc. Since the MathCad is the software for solution of applied mathematics tasks working with the method of real mathematics representation it enables easy entry of mathematics tasks and creation of computing protocols. That is why we use it for analytical calculations and effective processing of calculation procedures according to arbitrary codes used for solution of given problem.

Influence of vibration on service life was included in some systems.


Mochovce Nuclear Power Plant Complex seismic reassessment including detail inspections and their documentation. The

seismic database for 1. and 2. block contained around 7500 items (apparatuses, tanks, pumps, blowers, steel structures, pipeline branches, fittings, valves, etc.).

Members of our staff made detail stress and strain analyses of the following equipment

and facilities: 1. block: 3 types of apparatuses (detail analysis) including the supporting steel structures

11 types of tanks (interaction problems at seismic excitation) including the anchorage of supporting steel structures of the vacuum bubbling tower

2. block: 3 types of apparatuses (detail analysis) including the supporting steel structures 12 types of tanks (interaction problems at seismic excitation) including the anchorage 12 technological platforms

We can select at random: SAOZ heat exchanger, regenerating heat exchanger with after cooler, cooler of steam-gas mixture, active concentrate tank, tanks of emergency level of boric acid, hydro-accumulators, etc. 1. and 2. block: - piping systems – analyses of similar systems like for Temelín nuclear

power plant.

* Members of our staff also supervised the documentation of all stationary pressure vessels

that were manufactured in Královopolská Brno. They supervised observation of particular codes and rules (including design codes) that were specified in contracts. Each pressure vessel received an approval certificate that became part of complete documentation of the pressure vessel.

Pressure vessels were of various design and determination (e.g. pressure vessels for nuclear power plants, columns, heat exchangers, agitators, storage tanks, filters, chlorine containers and special tanks). The total number is more than a thousand pressure vessels that were supplied as part of complete units or masterpiece products. There are a few examples like Slovnaft Bratislava, CHZ Litvínov, Duslo Šaľa, nuclear power plant (NPP) Dukovany, NPP Temelín, NPP Jaslovské Bohunice, steam reformings in Russia, refineries in Iraq, Syria, etc.
