Abstract

Fibre reinforced polymer (FRP) composite materials have become an important target for providing innovative structures in civil engineering applications. FRP composite structures have been used as a replacement for old degrading traditional structures or building new structures. This paper describes a methodology and results for an optimal design of innovative structural fibre composite sandwich floor panel by using Finite Element (FE) and multi-objective design optimization methods. The materials cost and the structural panel weight minimizations are regarded as two objective functions for the design target. The multi-objective simulated annealing (MOSA) algorithm was used to find the optimum design variables. The optimization results show that the skin orientation of ±45 degrees is the best design for two-way square floor panel design.
