Calculation Example – Cantilever Beam with point loads. Featured

Draw the shear and moment diagrams for the cantilever beam (units KN,m).

Calculate the internal forces for the cantilever beam with the uniform loading q=10KN/m.

A rectangular column (400mmX400mm) is constructed of concrete and four steel reinforcing rebars. An axial force of 1000KN is subjected on the column. What is the diameter of the steel bars if the ¼ of the load is transferred to the steel bars and ¾ is transferred to the concrete? ( EST=200GPa, Ec=25GPa)
