Formatted abstract
In this research, cold-formed steel walls were tested with different wall configurations braced particularly with steel sheathing. The purpose of this research is to evaluate the lateral response of cold-formed steel wall subject in order to improve the lateral load capacity. The conducted experiment on was based on cyclic loading which simulates earthquake loading. With the aid of rig machinery, cyclic loading method comprises load exertion on the positive displacement followed 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 noggins, double end studs and additional reinforcement of screws at corners were found out 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 significance acquired from this research is that by understanding the function and the impact that structural elements have on cold-formed
steel walls, the lateral load capacity and overall lateral performance of cold-formed steel walls can be further improved and modified with newer concepts in the future research. After all, cold-formed materials are economical and advantageous in many aspects for today’s construction application.
