concentrated load of 15 kN at the free end in addition to its self weight. Design
the beam using M25 concrete and Fe 415 grade steel.

Discuss the IS code provisions for the design of RC beams subjected to
combined shear and torsion.

An isolated simply supported T beam has a flange width of 2400 mm and flange
thickness of 120mm.The span of the beam is 3.6m. The effective depth of the
beam is 580 mm and its width of the web is 300 mm. It is Reinforced with 8
Numbers 20mm diameter bars of 415 grade. Determine the Moment of
Resistance of the section. Use M20 concrete.

Design and detail a simply supported RCC slab 4m x 10m. Assume a live load of
4kN/m’. The slab is supported with 230 mm thick walls around. Use M20
concrete and Fe415 grade steel.

PART C
Answer any two full questions, each carries 20 marks.
Design an interior panel of a continuous slab system with effective dimensions

4m x 5m subjected to a live load of 4 kN/m?. A floor finishing of 120 mm water
proofing is applied having a unit weight of 18 kN/m? over the slab. Use M25
concrete and Fe415 steel. Detail the slab with top and bottom plan showing
typical sections.

Explain long column and short column.

Why does the code require all columns to able to resist minimum eccentricity of
loading?

Design a circular column of diameter 500 mm and effective length 3 m to carry
an axial load of 3000 KN. Provide helical reinforcement as transverse
reinforcement. Use M30 concrete and Fe415 steel.

Explain the procedure for estimation of flexural crack width in reinforced
concrete members as per IS456.

Sketch the reinforcement details of a straight flight stair supported on landing
slab.

Determine the area of longitudinal steel to be provided in a column of size 500
mm x 700 mm subjected to a axial load of 2500 KN. The unsupported length of
the column is 4.10 m. The column is held in position and restrained against

rotation at both the ends. Use M25 concrete and Fe500 steel.
