Abstract

As a country prone to earthquake disasters, seismic-resistant building design in Indonesia is one of important key in minimizing the impact of losses due to the damage caused. In building construction, innovation using cold-formed steel material is currently growing rapidly because of its advantages, such as very light weight, low prices, and practicality in assembly. For this reason, this experimental research focuses on the utility of cold-formed steel as a building frame using a variety of sheathed wall panel materials. The purpose of the study is to observe the structural strength of cold-formed steel frames with void panel walls subjected to seismic lateral loads. Two types of panel materials are commonly used, namely plywood and fiber cement board (FCB) which are installed on one side with the same thickness on the column of the frame test specimens. From the test results, the usage of sheathed wall panels in the cold-formed steel frame structure can increase its maximum lateral load capacity. The larger the area of the wall panels used, the greater the maximum load that can be resisted. Both of tangent stiffness and secant stiffness, the greater area of sheathed walls used will increase the shear stiffness of frame specimens. For all specimens, the FCB specimens have higher structural strength than frame with plywood sheathed walls.
