Investigating the use of autoclaved aerated concrete as an infill in reinforced concrete sandwich panels
Abstract Reinforced concrete composite sandwich panels are typically made of two concrete wythes separated by an insulating core of rigid polystyrene foam. The strength of the panels relies mostly on the efficiency of the shear connectors between the two concrete wythes. The rigid foam is too weak in shear and provides no contribution to the shear resistance of the connectors. In this paper, autoclaved aerated concrete (AAC) is used as an insulating core in place of foam and its efficiency to transfer shear between the sandwich panel layers is investigated. A total of nine full scale specimens made of rigid foam and AAC are tested under flexural load with varying types of shear connectors. Their ultimate load capacities are compared and their respective modes of failure are discussed. A detailed analysis of the stiffness of the shear connectors is done and used to predict the deflection of the panels under the applied load.
