This paper presents the results of the out-of-plane testing phase of the National Science Foundation Grant BCS 9102347. This project addresses the out-of-plane response to lateral loading of unreinforced, unanchored brick infill panels. The program consisted of the destructive testing of infill panels in two buildings and included three configurations of unreinforced masonry walls and one hollow clay tile wall partition. In all cases the loads were applied as point loads distributed by a bearing plate. The loads were generated using hydraulic jacks which were alternately loaded, unloaded, and reloaded in a manner which allowed the load deflection characteristics to be monitored under successive load cycles. Basic load deflection results are presented and correlated with a linear three hinged arch theory. The goal of this phase of the test program was to generate full scale test data from actual buildings which could be used to formulate requirements for retrofit standards.
