Project 2

1. 1. State the codal specifications of a compression member.

IS 800 2007
2. What are the different cross-sectional shapes used for a column member?

• Rolled I section
• Welded I section
• Hollow section
• Welded box section
• channel angle

3. 
   What is web buckling?

Web buckling is the sudden deformation in the structure when it subjected to loading.

4. 
   What is the formula to calculate the thickness of slab base as per IS800:2007?
5. 
   What are the loads we have to consider for the design of purlins?

Dead load,Live load

2. 1. Explain the steps involved in the design of a purlin member.

Load calculation,Check for basic section properties,Check for stresses,Check for deflection

2. 
   Draw a sketch representing a connection between two rafters at ridge level.
3. 
4. 
   How will you check maximum bearing pressure for a pedestal and draw sketch representing pedestal with anchor bolts.

Shear check,Tensile check,Combined unity check.

3. 1. Design a suitable ‘I’ beam for a simply supported span of 3 m and carrying a dead or permanent load of 18 kN/m and an imposed load of 40 kN/m. Assume full lateral restraint and stiff support bearing of 100 mm.
4. 
5. 
   Design a simple base plate for a ISHB400 @ 0.822 kN/m column to carry a factored load of 1500 kN.
6. 
7. Obtain factored axial load on the column section ISHB400. The height of the column is 3.0m and it is pin-ended. [ fy = 250 N/mm2; E = 2 x105 N/mm2; γ m = 1.10]
