Abstract

The theory of composite slabs with profiled steel sheet and subjected to different imposed loading cases and conditions has been reviewed and dis-cussed with the ultimate objective of formulating design optimization procedures that would eventually form the basis for establishing a multi-dimensional design optimization procedure towards manufacturing prefabricated composite slab systems. The Method of Feasible Directions as implemented in VisualDOC has been used to formulate the design optimization problem and to subsequently obtain optimal values of the various selected design variables under flexural- and transverse-shear strength and deflection constraints for this purpose. Design charts and tables have been produced for different spans, materials and imposed loadings. The developed procedure can be extended to cover other parameters, design variables and a variety of requirements and the process can be used to establish a variety of composite slabs sizes. Numerical experience has been provided to demonstrate the proposed method.
