The difficulties in assessing the probable deformation and force states of structural wall buildings under lateral earthquake forces were evaluated by means of laboratory test results from a five-story full-scale reinforced masonry structural wall research building tested to failure at the University of California, San Diego, under simulated seismic loads. The individual structural components and actions which contribute predominantly to the seismic response characteristics of a structural wall building, such as axial loads on walls, coupling between structural walls, lintel beam force, and deformation capacities, as well as floor and wall-flange participation were evaluated based on individual component tests, the full-scale prototype test, and parallel diagnostic analyses. The importance of a realistic assessment of these parameters in a capacity design approach for structural wall buildings was evaluated. The outline for rational design models which allow a prediction of the complex behavior characteristics of structural wall buildings for all design limit states is presented in this paper.
