Minimum volume of curtailed reinforcement in rectangular slabs
It is well recognized that the bottom reinforcement in rectangular slabs subjected to uniformly distributed load may be curtailed near the edges. Such reinforcement arrangements are naturally more economic than those in which the bottom reinforcement is continued to the supports. Most of the minimum reinforcement solutions for rectangular slabs deal with the latter type of reinforcement arrangement. In this paper, minimum reinforcement solutions for rectangular slabs having curtailed bottom reinforcement are presented. The solution is based on the theory of optimal plastic design for piecewise constant reinforcement. Solutions are presented for slabs with all edges fixed, and with two opposite edges fixed and the other two simply supported, for different aspect ratios of the slab. The minimum moment capacity volumes of the slab are found to be about 10-25% less than those of the slabs in which bottom reinforcement is not curtailed.
