Abstract

With increasing demand for midrise buildings, automated prefabrication, design for manufacturing and assembly (DfMA), and sustainability, a novel material-efficient post-tensioned (PT) composite steel-timber (CST) stiffened wall system has been developed. As opposed to cross-laminated timber (CLT), this fully prefabricated panelized composite system consists of an engineered wood panel that is integrally stiffened by timber studs and steel square hollow sections (SHS). Each SHS additionally accommodates a PT rod and panel-to-panel connections, allowing for quick onsite assembly, permanent tie-down, and self-centering inverted pendulum rocking. This study presents and evaluates the structural..
