Abstract

After the 1995 Kobe earthquake, Japanese design codes were changed from elastic to plastic design. However, due to the lack of sufficient researches, concrete design specifications for beam-to-column connections of steel frames commonly used in overpasses, were not clearly outlined. The beam-to-column connections determine the strength and ductility of steel frames and therefore it is important to investigate the mechanical behavior of the connections under cyclic loading. Experimental researches into the effects of varying various parameters have been undertaken. However, the data obtained from the experiments has been insufficient due to high costs, extensive manpower and time needed to undertake experiments. Therefore, finite element analysis methods have successfully been used to accurately simulate the structural responses of beam-to-column connections. In this paper, using FEM, the effects of width-thickness ratio parameters on the ultimate strength and ductility of connections are investigated.
