4. Design a symmetrical deep beam one half of which is shown in figure 1. It supports two

loads kN at 400 mm from supports on each side. Assume fy = 415 N/mm

2

, grade

25 concrete and effective span 1650 mm.

FIG.1

5. A simply supported rectangular slab 4.5 m long and 3 m wide carries an ultimate load of

15 kN/m

2

. Determine the design moments for case when the moment of resistance of the

short span is 30% greater than that in the direction of long span.

6. Explain the portal method for analysing a building frame subjected to horizontal forces.

7. A two span intermediate frame of a multi-storeyed building is shown in figure 2. The

frames are spaced at 5 m intervals. The dead load and live load per meter run of the beam

may be taken as 15kN/m and 20 kN/m respectively. Analyse the frame using two cycle

method of moment distribution. If wind loads of 15 kN and 30 kN are acting at joint A, B

and C respectively. Analyse the frame by portal method. Assume that all the columns

have equal area of cross section for the purpose of analysis.

FIG.2

8. A square slab is simply supported on three sides and is free on the fourth side. If the

moment capacities are equal in both directions, calculate the collapse load.
