Q.4 A doubly reinforced concrete beam is 400 mm wide and 600 mm deep to the centre of tensile reinforcement. The compression reinforcement consists of 4 bars of 16 mm diameter, and is placed with its centre at a depth of 40 mm from the top. The tensile reinforcement consists of 4 bars of 20 mm diameter. The section is subjected to a bending moment of 100 kN-m. Determine the stresses in concrete and steel. Take m = 16.

(b) Discuss the role of engineer, architects, user and builder in building planning design and construction.
Q.6 (a) Design a circular column with helical reinforcement subjected to a working load of 1500 kN. Diameter of the column is 450 mm. the column has unsupported length of 3.5 m and is effectively held in position at both ends but not restrained against rotation. Use limit state design method. Use M25 concrete and HYSD Fe415 steel.
(Q.7 (a) If maximum strain at a highly compressed zone is considered as 0.0025 then the depth of neutral axis for the balanced section will be?
Use following data:
Width of beam = 250 mm
Overall depth of beam = 400 mm
Effective cover = 50 mm Area of steel in tension = 500 mm²
Grade of concrete and steel are M20 and Fe250 respectively.
(b) A reinforced concrete beam of rectangular cross section of breadth 230 mm and effective depth of 400 mm is subjected to a factored shear force of 120 kN. The grade of concrete, main steel and stirrup steel are M20, Fe415 and Fe250 respectively.
Area of main steel provided gives, design shear strength of concrete (Tc) as 0.48 N/mm². For a limited state of collapse in shear, design shear reinforcement.
Q.8 A hall has clear dimension 3 m x 9 m, with wall thickness 230 mm. The live load on the slab is 3 KN/m² and finishing load of 1 KN/m² may be assumed. Use M20 concrete and Fe415 grade steel. Design the slab.
