A reinforced concrete beam with b=300mm, h=670mm,and d=600 mm, having
a span of 7.3 m, can be considered as a fully fixed at the left support and simply
supported at the right end. It is reinforced for positive bending with 8-16 and for
negative bending with 4816 plus 418. Calculate the collapse load using the plastic
hinge method. (20%)
