Consider a three$-$span continuous steel I$-$beam carrying the transverse loads as shown in Figure

The dimensions of the I$-$beam are given in Figure $2.$ Assume the Young's modulus $E=200$

GPa and the yield stress ${}_y=250$MPa for steel. By using iSA for the bending analysis of the

continuous beam, check whether the following design criteria are violated:

Deflection should not exceed $\frac{L}{360}$ where $L$ is the span length between supports

Shear stress should not exceed the maximum allowable shear stress given by $0\mathrm{.}4{}_y$

Bending stress should not exceed the maximum allowable stress of $0\mathrm{.}66{}_y.$
