Abstract

Existing work on structural optimization do not consider all the constructability issues related to precast construction. This paper presents an optimization model for large span floor slabs and roof slabs constructed using precast technology. A case study is taken from an actual construction project of an indoor sports complex for illustrating the application of the approach. A stochastic global search algorithm called RANPAS is used for optimization. This study demonstrates the potential for optimizing large span roof and floor structures subject to the specific constraints imposed by precast construction technology. About 21% savings in the cost of material is obtained by the optimized design compared to a conventional beam and slab design.
