Influence of the Fuse Sliding Stength on the Ultimate Capacity of the Engineered Fused Infills By Finite Element Method

Infills have considerable effects on seismic behavior of buildings and should be considered in the analysis or be isolated from the containing frames. Despite, most types of infills cannot be regarded as engineered elements, specially for the lack of sufficient ductility and normally ignored in the analysis phase. Recently a new type of infill is proposed, that has a frictional fuse at the mid-height. High ductility of such infill has been confirmed through experimental studies. In this paper finite element analysis results of the fused infills are presented to study the relation between their ultimate capacities and the fuse sliding strengths. For this ABAQUS 6.8-1 was applied after being confirmed by the experimental results. The obtained results show that the infill ultimate strength rises by increasing the fuse sliding strength, however will remains constant after a certain amount, depending on the infill propertie. Moreover, infills and frames will behave in their optimum capacities when such infills are applied in the frame.
