--M 30 and M 20.

--High Quality.--Strength.

--Should be leak proof.

--Should not crack.


12/34

--Permissible stress should not exceedthe limit.

--Permissible stress in directtension=1000kg/cm^2.

--Tensile stress in bending=1000-1250kg/cm^2.


13/34

--0.3% of gross cross sectional area upto 100mm thickness.

--0.2% of gross cross sectional area for100-450 mm thickness.

--0.2% of gross cross sectional area for>450 mm thickness in each direction.

-The object of using them is to fill the pores of theconcrete and to obtain a dense and lesspermeable concrete.

-Commonly used is HYDRATED LIME.-Other agents like powdered chalk or talc,

Sodium silicate Zinc sulphate, Calciumchloride etc., used.


15/34

Parameters:

-Concrete for container portion M30.-Concrete for staging portion M20.

-Steel HYSD 415N/mm^2.


16/34

-Capacity 150000L.

-Staging 12m.

-Seismic zone-3.

-Staging to be designed with M20 and executed

with M30.

-Number of columns supporting the ESR = 5

-Number of columns inside container =1

-Number of braces =3

-Size of container(diameter) =8m.

-Size of column supporting ESR(diameter) = 0.4m.

-Size of column inside container(diameter) =0.2m.-Braces =250*350mm.

-Roof beam =200*300mm.

-Floor beam =300*600mm.

-Floor ring beam =300*300mm.

Types of loads :

--Dead loads--Imposed loads

--Wind loads--Earthquake loads


20/34

Involves self-weight of

--Container--Columns

--Braces--Railing

--MS ladder


21/34

--Imposed also known live loads.

--Load over the roof covering while workers over

it i.e. load of persons it is calculated as 0.2 KN/m

.

--This load is applied over the container slab.


22/34

--Wind is air in motion.

--Wind load is predominant in the columns andneglected in the container.

--Wind loads are calculated according toIS:875(part 3).

--Intensity of wind and exposure are applied in

the directions as required .


23/34

-Dead load of slab =300kg/m^2.

-Wind pressure =150kg/m^2.

-Live load on roof =100kg/m^2.

-Live load on walkway slab =300kg/m^2.

-Density of concrete =2500kg/m^2.-Density of water =1000kg/m^2.


24/34

--The tank is designed in the seismic zone3,hence design for earth quake loads isnecessary.

--This is very important for structures as it is

made strict provision by law.--The earth quake intensities are calculated asper the code IS:1893.


25/34

-Safe bearing capacity of soil(SBC) =.6KN/m^2.

-Depth of foundation =3m.

-Depth of ground water table =7m.

-Seismic zone =3.


26/34

-Total load on roof slab =500kg/m^2.

-Spacing of 8mm diameter bars=200 c/c both ways at

bottom and alternate bars bent.

-Spacing of 8mm diameter bars =400 c/c both ways attop.


27/34

-Design wind pressure =150kg/m^2.-Basic wind pressure =39m/s.

-Probability factor =1.06.

-Topography factor =1.

-Design wind speed =43.66m/s.


28/34

-Load from base(floor) beam =296t.-Weight of water =158t.

-Weight of staging =49t.

-Tank empty =154t.

-Tank full =312t.

Analysis is done using STAAD PRO developed

by BENTLEY . Once the loads and load combinations are

assigned to the structure, analysis is to be done.

Only the staging part is analyzed by staad pro.
