Finite Element Modelling for Lateral Behaviour of Infilled RC Frames with Openings

Abstract

Masonry infills are commonly used in reinforced concrete (RC) frame structures. In this paper a separate finite element modelling method is proposed and used to study the lateral behaviour of single-storey one-bay masonry infilled frames with openings under monotonic horizontal loading. The interface friction model and the surface-based cohesive model are combined to simulate masonry interface and the interface between masonry wall and RC frame. Damage plastic model of material property is adapted to capture the brittle behaviour of concrete and bricks. Appropriate experimental data available from the literature are utilized to verify the model. The comparison between the numerical analysis and test results indicates that the proposed FE modelling method can predict the masonry infill wall’s crack patterns and the lateral strength and stiffness of the structure with window or door opening successfully.
