MASONRY INFILL PANELS SUBJECTED TO CYCLIC IN-PLANE LOADING.

Abstract

A test program of three frames, one unfilled, one filled with reinforced but grouted hollow bricks and one filled with reinforced grouted hollow bricks is reported. The panels, in nominal 4 in. reinforcing bricks, were 3 ft-10 in. high by 5 ft-11 in. long within a reinforced concrete frame of 8 in. by 6 in. section. An in-plane horizontal load was applied to the top of the single-storey single-bay structure. The test results confirm existing analysis methods for stiffness calculation but the strengths of the infill panel frames were not well predicted by these methods. In particular, the behavior of the panels under large static cyclic loading is studied.
