Proceedings from Seismic Response of Masonry Infills

Abstract

This volume offers the proceedings of a two-day workshop focused on the seismic response and performance of masonry infills. Researchers and engineers made a total of sixteen presentations, which are reproduced here, and a number of separate groups convened to discuss the mathematical modeling of masonry infills, overall system behavior, evaluation criteria, and the rehabilitation of existing buildings with masonry infill. Overall, the papers dealt with concrete or clay-unit masonry in concrete or steel frames subjected to static or dynamic, in-plane or out-of-plane seismic forces. Six papers present laboratory experiments. One paper describes field experiments. Five describe analytical studies and the remaining four papers present case studies. A number of general themes emerged from the workshop: lateral strength of infill frames could be represented with equivalent struts; standard guidelines for the evaluation of rehabilitated or repaired infill systems are needed; and standard relations for the assessment of infill strength are also necessary. Finally, one of the workshop's highlights was the joint participation and interaction of both researchers and practicing engineers.<BR>
