Project 2

Model & Design a Proposed PEB Warehouse using STAAD. Pro with following Technical specification.

SOLUTION:

• Mdel the structure in STAAD as per the given data as shown in fig.

• Assign the property to each & every member.

• Model & assign to mezzanine floor, column & beam as per the given data.
• Go to support tab, define the support & assign to the nodes.

• After assigning supports go to specification tab, Add & assign it for the same.

• Once adding specification is over we have to add load defination, load cases & combination as per the given data.
• In order to add all load we have to calculate it first.

Load Calculation:

Seismic Load:

Zone Factor = 0.16 (Zone III)

Response Reduction = 4 (Ordinary Moment Resisting Frames)

Importance Factor = 1.0 (Category 4)

Soil Type = 1.0 (Hard Soil – As per Staad)

Type of Structure = 3.0 (Steel Moment Resisting Frames = As per Staad)

25% of Live Load on roof shall be considered for calculation of seismic forces.

100% of collateral load on roof shall be considered for calculation of seismic forces.

50% of (Live load + Collateral load) on mezzanine floor shall be considered for calculation of seismic forces.

100% of Dead load shall be considered for calculation of seismic forces.

For seismic in longitudinal direction, diaphragm action due to purlin and sheeting can be considered. Diaphragm actions should not be used while designing bracing system for wind load.

Provisions of Chapter 12 of IS: 800 - 2007 need not be considered while designing structure.

Dead Load:

1) Self weight - Assigned to the entire structure as shown in the print screen given below-

2) Purlin - 10 Kg/m² and 10 kg/m2 for roof sheeting are as per calculation and print screen given below-

= 20 x 6 (Bay width along span of truss) = 120 Kg/m²

= 1.2 kN/m² on main rafter

&

0.6 kN/m² on Gable frame

3) Mezzanine Floor – Load due to 230 mm thick and 4 m height wall around the periphery of Mezzanine Floor.

= 20 X 0.23 X 4 = 18.4 kN/m (on Both Mezzanine Floor)

Collateral Load:

On Gable frame - 2.12 kN/m

On Main frame - 4.24 kN/m

Live Load:

On Gable frame - 2.28 kN/m

On Main frame - 4.56 kN/m

On Mezzanine Floor - 4 kN/m² or MEMBER LOAD = 6.8 kN/m on all secondary beams except end beams where load will be 3.4 kN/n (4 kN/m² x 1.78 m (spacing of secondary beams)

6. MEMBER LOAD = 6.8 KN/m on all secondary beams except end beams
7. MEMBER LOAD = 3.4 KN/m on secondary beams at ends

Wind load:

• Once all the calculation is done we have add the defination, cases & combination.

• After applying all the loads we have add the load combinations as per the given data.

• After adding all the combination add all design parameters & assign it for the same.

• Give the command perform analysis & run the analysis for the results.
• Here the analysis is successfully done with out any errors.

• Once the analysis is done one can view the results as shown in fig.
