Inelastic dynamic response of 3D reinforced concrete infilled frames

Abstract

An inelastic finite element model to simulate the behaviour of 3D reinforced concrete frames infilled with masonry panels subjected to static load and earthquake excitation has been presented. Under the loads the mortar may crack, causing sliding and separation at the interface between the frame and the infill. Furthermore, the infill may become cracked and/or crushed which then changes its structural behaviour. It may render the infill ineffective leaving the bare frame to take the entire load, which may lead to the failure of the framing system itself. In the present study, 3D reinforced concrete infilled frames have been analysed using the finite element method.
