Abstract

![CDATA[The purpose of this study is to complete the previous research publication of the third author on the subject of cold-formed steel structures. This research aims to evaluate the lateral response of cold-formed steel walls in order to improve the lateral load capacity. Coldformed steel walls were tested with different wall configurations braced particularly with steel sheathing. The conducted experiments were based on cyclic loading in lieu of actual earthquake loading. Within a specially made testing rig cyclic loading method comprised load exertion on the positive displacement followed by a reverse direction reaching towards the negative displacement. For each wall, the cycles would keep repeating as the displacements increased further until both negative and positive maximum displacements were reached while the progress of load capacity was recorded and plotted into a hysteresis graph. From the conducted tests, the structural elements such as double noggings, double end studs and additional reinforcement of screws at corners were found to be the dominant factors that improved the lateral strength of the walls. Despite the slight contribution to the lateral load capacity value, the wall with the smallest size of fastener spacing seemed to sustain the lateral load capacity throughout the cycles until the damage was reached. The understanding obtained from this research of the function and the impact of individual elements on the behaviour of the cold-formed steel walls can help improving the capacity and the ductility of the system.]]
