PARTA
1. The portico of a building consists of cantilever beams of effective span 3m, spaced at
9

2.5m centre to centre. The beams support 120mm thick slab. LL on slab is 1 .5 5 ۸/۰
Using M20 concrete and Fe4E5 grade steel design an intermediate beam, if slab is flush
with top of beams.

2. Design a rectangular beam section with following data. Size 300mmx 550mm subject 9 to an
ultimate twisting moment 25kNm combined with an ultimate bending Moment of 60 kNm and
ultimate shear force of 50 kN. Assume M20 concrete and Fe415 grade steel.

3. Design the reinforcement of a column with lex=leF3.5m and size 300mmx 500mm 9 subjected to
factored axial load of 1250 kN and factored biaxial moments Mum—180 kNm, Mur 100 kNm.
Assume M20 concrete, moderate exposure conditions and Fe41 5 grade steel.

PART B

4.a. Distinguish between short term deflection and long term deflection in reinforced 3 concrete
flexural members

b. A rectangular simply supported beam of span 4m is 300mm x 550mm in cross section 6 and is
reinforced with 3 bars of 16 mm diameter on tension side at an effective cover of 50 mm.
Determine the short term deflection due to an imposed working load of 1 5 kN/m (excluding
selfweig ht). Assume M20 concrete and Fe 415 steel.

5: Design an interior beam column joint (Type |) for the following data. 9 Column with 600mmx600mm
with 8 numbers of 25 mm diameter. Column factored load 1300 kN. Storey height 3m. Beams on
either side 300mm x 500mm with 3 bars of 28mm diameter on the top and 3 bars of 20mm dia at
bottom. Assume fck- 30N/mm and fy 41 N/mm.

6. a. Explain the principle of shear wall analysis. 3
