Abstract :

Composite walling system consisting of two skins of profiled steel sheeting and an infill of concrete is novel form of construction. Such walling system has great potential to be used as gravity and lateral load resisting elements in buildings. The strength, stiffness, ductility and energy absorbing capacity of composite walls subjected to axial, monotonic/cyclic shear and impact loadings will be described based on comprehensive experimental and theoretical investigations. The fire durability of the walls subjected to high temperatures will also be presented based on residual strength/stiffness/energy absorption capacity. The innovative feature of such walls is the use of new engineered high performance concretes (HPCs) with high strength, high ductility (strain hardening capacity) and micro-cracking characteristics developed at Ryerson University for the last few years. Such HPC composite walls have shown superior performance compared to those made with traditional concrete in terms of strength, ductility, energy absorbing capacity and durability as well as post-impact strength/stiffness/ energy absorbing capacity. Analytical models/design equations for the load resistance of composite walls are developed and their performance validated through experimental and finite element modeling.
