The aim of this study is to improve the seismic performance of framed buildings with masonry infill walls (MIWs) by providing practical recommendations for their design. Finite element models validated against experimental data are used to investigate the effects of different factors, such as the aspect ratio, gap size and location, and steel plate connectors, on the in-plane (IP) and out-of-plane (OOP) behaviour of MIWs. Optimal gap configurations for MIWs are proposed to reduce their interaction with steel frames until large deformations occur. A simple method of stiffening MIWs with steel plate connectors is suggested to ensure their stability despite the gaps. Furthermore, MIWs effect on the fundamental period of the structures is examined, and a 20% reduction in the period for buildings with MIWs is recommended. Additionally, it is shown that the OOP stability of MIWs can be enhanced by adding small angle sections on the perimeter of MIWs. |
