ABSTRACT

The infilled frame structure has advantages compared to the open frame structure which provides stiffness and strength to withstand lateral forces. The infill-walls that are installed between the beam and column contribute to the lateral stiffness. Infill-walls placed between beam and column provide lateral stiffness and better behavioral resistance and performance. Based on numerical analysis, the infill-walls are usually modeled using shell elements or strut elements. Modeling with a strut is simpler than shells for the linear or nonlinear analysis. However, an equation is needed to determine the strut width that is used for each wall panel opening condition (wall with and without openings). The method of determining the strut width equation is to approach the experimental results with element shell models. Certain number of the strut width is determined to get the same deformation value as the shell models. Research on infill-wall structures is mostly carried out on reinforced concrete (RC) frames but rarely carried out on steel frame structures. This study shows how strut width equation obtained from RC-infilled frame affects steel-infilled frame. RC structures and steel structures have different characteristics so there will be also differences in behavior due to the addition of infill walls. The strut width equation for modeling infill-walls in RC frames cannot be fully applied to steel frame structures, especially for walls with openings. Modifications are needed to the strut width equation of RC-infilled frame by multiplying with coefficient 0.4 so that the results can be suitable for steel-infilled frame structures. Comparison of behavior and performance are also presented in this paper.
