span of 17 m is resting ag dder if it is about to slip.

A post consists of concrete with 15-20 mm diameter of steel rods. The post is 30 cm in diameter. The limiting stress of the steel is 140 MPa and that of concrete is 15 MPa. What maximum axial load that can be safely carried by the post if Es=200 Gpa and Ec-12 Gpa?

a triangular beam having a base 400mm and a height of 500mm. if fc'=25MPA and the subjected maximum moment is 15 kN- m. considering uncracked analysis. what is the actual tensile stress?

A lightweight reinforced concrete beam is 400 mm and 630 mm deep.The beam is simplysupported over a span of 7.7 m and carries a uniform dead load of 12 kN/m excluding its ownweight and a uniform live load of 12 kN/m. The beam is reinforced for tension only with six-28mm diameter bars with an effective depth to tension bars of 570 mm. fc’=20.7 Mpa, fy=344.8Mpa. Modulus of Elasticity of Concrete, Ec = 21,750 Mpa and Es = 200 GPa a. Calculate the maximum instantaneous deflection due to service loads. b. Calculate the deflection for the same loads after five years assuming that 50% of thelive load is sustained.
