Cyclic Loading Tests of Masonry Single Piers. Volume 1: Height to Width Ratio of 2
A multistory masonry building research program was initiated in September 1972, and has continued for the past six years. After an extensive review of the literature dealing with resistance of masonry to earthquakes, it was concluded that shear walls penetrated by numerous window openings were the components of multistory masonry buildings most frequently damaged in past earthquakes, and it was decided that an experimental study of the seismic behavior of such components was necessary. This report presents the results of fourteen cyclic, in-plane shear tests on fixed ended masonry piers having a height to width ratio of 2. These fourteen tests form part of a test program consisting of eighty single pier tests. The test setup was designed to simulate insofar as possible the boundary conditions the piers would experience in a perforated shear wall of a complete building. Each test specimen was a full scale pier 80 inches high and 40 inches wide. Two types of masonry construction were used; a hollow clay brick type, that used an 8 inch wide unit, and a double wythe grouted core clay brick, 10 inch thick wall, that consisted of two wythes 3 1/2 inches thick and a 3 inch grouted core. The variables included in the investigation were the quantity of reinforcement and the type of grouting. The results are presented in the form of hysteresis envelopes, graphs of stiffness degradation, energy dissipation and shear distortion, and tabulated data on the ultimate strength and hysteresis indicators. A discussion of these test results is presented but no definitive conclusions are offered. These will be included in a final report at the completion of the eighty tests.
