Study the Interaction Behaviour of Integrated Infilled Frames with Interface Materials

Abstract

High-rise or multi-storey buildings are more prevalent in urban regions because of industrialisation and population concentration. Multi-storey concrete buildings always have infill masonry walls in framed constructions, using masonry or concrete brickwork as infills, partition walls typically come with frames for practical reasons. Because they absorb and disperse greater seismic forces. Although a stiffer structure attracts greater seismic loads, the presence of infills has significantly contributed to building collapse brought on by intense ground shaking brought on by an earthquake. In earthquake-prone areas, infill walls have an impact on the ductility, stiffness, and strength of framed structures. In regions with greater seismic zones, infill frames perform better. Because of the composite action between the frame and the infill, infill frames are more resistant. In this study, the analysis is conducted using an RCC square frame model with a single bay and one storey, along with masonry infilling. In this model, the frame's opposing corners are used to apply the loading, in which the behaviours are similar to the RC structure prototype under lateral loading. In this infilled frame, brick masonry is used as infill materials and different interface materials are used (cement mortar, foam rubber, cork, bitumen, recycled plastic), and applying the cyclic loading on the frame. These are analysed by FEM software (Abaqus).
