Behaviour of Seven-Storey Reinforced Concrete Frames with Infill and Interfaces Under Static Load

Abstract

AbstractConstruction of tall buildings is most common in this twentieth century. Technological development and the modern equipment have reduced the complications in design, analysis and construction of these structures. The seismic damages in these structures are unavoidable unless they are technically designed to be stable or isolated from seismic actions. The energy absorption and energy dissipation in these buildings change based on infill type, openings in infill and interface type used under different loading actions. It is essential to study the combined behaviour of RC main frame and the non-load-carrying structural elements under static and cyclic loading conditions. In this study, an analytical work is carried out using finite element modelling software to understand the performance of multi-storey reinforced concrete (RC) frame, RC frame with infill and infill frame with pneumatic interface pressures (in psi). The structural parameters like load-carrying capacity, maximum displacement, stresses and stiffness under static loading conditions are compared with the RC bare frame.KeywordsRC frameMasonry infillPneumatic interfaceLateral load
