Input Strategy

� The physical system is represented by the assembly of

simple “stick” elements / 3D Beams

� Two node numbers identify the ends of each element

� Enter one piping element per spreadsheet

� Add boundary conditions of loads

Point vs. Carry-Forward Data

� Entered data is automatically “carried forward” to the next element where appropriate (shown in red).

Building and Using Load Case

� CAESAR II recommends loads cases for new jobs.

� The recommended load cases are usually sufficient to

satisfy the Piping Code requirements for the

Sustained/primary and Expansion/secondary loads

� CAESAR II keeps the load cases from the last analysis.

� CAESAR II does not “recommend” occasional load sets.

Building and Using Load Cases

� Primitive Components (left): Weight/Temp/Pressure/Hanger loads/etc

� Basic Load Cases: combine primitive components/loads

� Combinational Load Cases: combining the basic load cases

� Order: all basic load cases MUST BE defined BEFORE any combinations.

Input BasicsInput Basics 1818

Building Load Cases

� Load cases usually serve three purposes in a CAESAR II

analysis

– Develop code-defined stresses

– Examine structural response at various states (e.g.

installed and operating condition)

– Collect data to size spring hangers

Static Output: Selecting / Generating Reports

� Many reports available – which do you need?

� Input Echo (describes the system)

� Miscellaneous Report (intermediate calcs)

� Load Case Report (what options chosen)

� Hanger Report

� Displacements: OPE (interference) + SUS (weight sag)

� Restraints (or Summary): OPE (hot loads) + SUS (installed loads)

� Stresses (or Code Compliance): SUS (most codes) + EXP (most

codes) + OCC (if present) + OPE (some codes)
