A composite precast slab will be an economical alternative in case of constructing on a extremely cold region like antarctic. Side ratio optimization of the slab should be performed to solve the difficulties of using construction equipments and moving materials. Optimized side ratios by FEM and orthotropic plate theory are calculated and the results can be used to design the composite precast slabs.
