The W= 5 kN/m uniformly distributed loaded composite steel beam is shown in Figure (a). The steel composite section consists of two steel plates, each with dimensions of 229 x 30mm and a universal beam section Section1 (See Table 1) are bolted together to form the composite section as shown in Figure (b). The 16 mm diameter bolts are spaced longitudinally every 150 mm. The sectional properties are given in Figure (c) and Table 1. The modulus of elasticity for steel is 200 GPa. a a P Steel plate I UB Section 10 m Figure (a) Simply supported beam w kN/m Steel plate (b) Section a-a (dimensions not to scale) d X E y.
