Acolumn of rainforced concrete has steel reinforcing rods running through its entire length and parallel to the column axis. If concrete has (E) of 15GPa and tensile strength of 2.8 MPa and the steel rods has (E) of (210) GPa and tensile strength of(400) GPa Determine the modulus of elasticity and tensile strength of composite if the steel rods occupy 10% of cross-sectional area of the column

Determine the bulk modulus for each of the following materials: (a) rubber, Er = 0.4 ksi, nr = 0.48, and (b) glass, Eg = 8(103) ksi, ng = 0.24.

Column AB is made from high strength pre-cast concrete and reinforced with four in. diameter A-36 steel rods. The allowable normal stress for the high strength concrete and the steel are (allow)con = 2.4 ksi and (allow)st = 24 ksi, respectively. The modulus of elasticity for high strength concrete is 4.2 × 10³ ksi and for A-36 steel is 29 x 10³ ksi, (Figure 1) Figure 10 ft H 9 in. 9 in.
