| The results of 92 in-plane earthquake simulation tests carried out using a shake table on six reinforced concrete masonry walls at the University of Calgary are presented in this thesis. Four of the walls were heavily-reinforced concrete masonry shear walls, built to the specifications of the Canadian masonry code, CSA S304.1-04, and were tested to investigate their seismic performance. The testing program was developed to assess the effect of loading history, grouting and aspect ratio on the seismic performance of heavily-reinforced concrete masonry walls. Two of the walls were designed to fail in diagonal shear and were tested as a preliminary study of the shear strength of partially-grouted reinforced concrete masonry shear walls. The walls are cantilevered, single-storey walls with no openings and were loaded until major damage was observed and beyond major damage for some walls. A thorough description of the test set-up and results is provided, together with a discussion of the cracking patterns, displacements and the force-displacement responses of the walls. Ten free vibration tests were carried out on the walls to assess and report their viscous damping behaviour. |
