Behaviour and design of composite walls under lateral loading and combined loading

Abstract

This study aims to investigate the behaviour of concrete filled composite walls (CF-CWs) without any boundary elements under lateral loading and combined axial and lateral loading. Under this objective, an experimental programme was set covering both compact and slender CF-CWs utilising different connector types and arrangements. Specimens were designed with the aspect ratio (height to width ratio) of 1.9 so that the in-plane flexural behaviour dominated the failure modes. Meanwhile, for the combined loading, different axial load ratios (n) were applied to the specimens in order to investigate the effects of axial load and the relative lateral load-displacement responses.
