Dynamic Analysis of Reinforced Brick Masonry Infilled RC Frames Using 3D Elements under Seismic Loading

Masonry walls are provided basically for the purpose of partitioning and covering but they impart considerable strength and stiffness to the building frame for resisting loads. The strength and stiffness contribution of infill masonry is generally ignored in the design. Due to the uncertainty in the strength properties of masonry, separation of infill from frame, low tensile strength, brittle characteristics of masonry walls, less out of plane strength and stiffness etc. Reinforced brick masonry as infill in RC frames provide better contact at the interface. Their out of plane strength and stiffness is also higher. In this study an attempt has been made to carry out dynamic simulation of multistoried reinforced rat trap clay brick masonry infilled RC frames by finite element analysis.
