Seismic Behavior of Confined Masonry With Various Connection Details
Abstract eng: Test of confined wall panels under in-plane cyclic shear loading were performed to provide some insight into the effect of alternating the details of connection between tie-columns and masonry. Three different types of wall specimens (without any connection between masonry and tie-columns, tooth-linked and connecting by U-shaped stirrups in bed joints) built at a scale 1:1,5 were subjected to in-plane quasi-static tests. Mixed displacement-force control was used. Based on experimental test data we obtained: the interstory drift associated to damage grade according to EMS-98 [1], ductility, energy dissipation and failure mechanism. The average resistance envelope curves were obtained for three specimen groups and then simplified by bilinear curves. The behaviour factor q was evaluated for each investigated wall group.
