Abstract:In developing a design procedure for earthquake-resistant structures, information on demand as well as capacity has to be obtained. Data on demand are most conveniently obtained through dynamic inelastic analysis. Capacity values are generally deter-mined by tests of large-size specimens subjected to slowly reversed loads. In correlating demand with capacity, an important consideration is the degree to which the laboratory loading represents earthquake response conditions. A valid correlation is possible only if it can be shown, among other considerations, that the loading program used in tests is comparable to, or more severe than, conditions that can be expected under earthquake excitation. This paper presents the results of an investigation to determine appropriate loading programs for use in quasi-static tests to simulate response to earthquakes. The study is part of a combined analytical and experimental project to develop design procedures for earthquake-resistant structural walls and wall systems. In the first phase of the project, the structure considered is an isolated wall. Frame-wall systems are considered in later phases of the project.
