DESIGN OF STEEL STRUCTURES - MODEL QUESTION PAPER

PART A (5 x 2 = 10)

(U) 1. What is the purpose of providing battens in compound columns?

(R) 2. Why do compression flange requires lateral support?

(U)3. How do the beams fail?

(U)4. What is web crippling?

(U) 5. Under what conditions plated beams are used?

Part B (8+16+16 = 40)

6A) Find the design bending strength of ISMB 600 beam

(Or)

6B) Explain the design procedure for designing plate girder (Az)

7 A) Design a column to resist a factored axial load of 1500 KN. The effective height of column is 4.2m. Design the battening system too. Use two channels placed back to back.

(A)

(Or)

7B) Design a suitable slab base to resist an axial load of 500 KN. Use column section ISHB 400 @ 822 N/m. The base plate is to rest on concrete pedestal of grade M20.

(Ev)

8A) Design a laterally supported (simply supported too) beam to resist a load of 50KN/m of effective span 12m. The depth of the beam is restricted to 500mm. (Ev)
