Analytical modelling of podium interference on tower walls in buildings

Abstract

In regions of low-to-moderate seismicity like Australia, a common form of building construction is the one featuring a podium structure that supports a tower with smaller floor plan. This building layout is particularly favoured in metropolitan regions as it can cater for a mix of commercial and residential functionalities. This paper investigates the undesirable effects of podium interferences on the shear demands on the structural walls at and above the interface zone. Shear force redistributions between the connected structural walls were found to be the direct consequence of the differential restraints imposed by the podium structure. The generation of in-plane strutting forces in the sl..
