The previous chapter showed that plastic theory is usually rather difficult to apply to RC structures because of the limited plastic rotation capacity of concrete sections in bending. However, concrete slabs are almost always very under-reinforced. It is unusual to have sections with more than 1 per cent of reinforcement. Consequently slabs have considerable plastic rotation capacity and can be successfully analysed or designed by plastic methods.
