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
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.
