Abstract

The research aimed to study the behavior of cold-formed steel (CFS) structures with different sheath materials and framed shear walls to improve their resistance to higher forces in mid-rise construction. The study involved constructing and evaluating twelve full-scale specimens with varying building parameters at Port Said University. The primary focus was to investigate the behavior of cold-formed section shear wall panels under monotonic lateral loads. For the experiment, the walls were covered with thermal board and fiber cement board. Different factors like lateral load capacity, failure modes, and the relationship between load and displacement were studied. Tests were conducted on CFS wall panels sheath with different thicknesses of boards with and without strap bracing. The aim was to analyze the behavior of the specimens under lateral loads. The thermal board type is a new type used in Egypt compared to other types of sheeting. The Thermal board and the fiber cement board (FCB) is suitable for climate in Egypt. As a result, the thermal board and fiber cement board (FCB) is suggested to be investigated in this research. The aspect ratio of all the walls was 2:1and 1.333:1. All the shear walls had a steel thickness of 0.95 mm and had hold-downs in order to transfer lateral load and uplift from the frame to the foundation.
