Transcribed Image Text:

The concrete composite post in Figure 2 is 1.5 m long with a 0.3 x 0.3 m square cross- section. The post is reinforced by four vertical steel rods of the same length having a cross-sectional area of As = 0.00135 m2 each and is loaded by a single vertical load P = 600 kN applied on the rigid cover plate as shown below. The modulus of elasticity for concrete is Ec = 17 GPa, whereas the modulus of elasticity of steel is Es = 200 GPa. Determine the stresses in the steel rods and concrete.
