Abstract:

This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting with an infill of concrete. The steel sheeting acts as a permanent form obviating the need for temporary shuttering and false work and acts as reinforcement once the concrete has hardened. In tall buildings the in-plane loads are transmitted via the structural floors and frame to the walls. The behaviour of the wall under in-plane loading is, therefore, important for the analysis of building sway. Analytical models for the shear stiffness of the composite wall are presented and compared with the finite element analysis.
