The determination of loads and displacement demands for seismic design of reinforced concrete walls is typically accomplished in practice using elastic shell-element models and response-spectrum analysis methods. Here, the results of a series of shake-table tests of reinforced concrete wall specimens are used to evaluate commonly used and newly proposed methods for determining the effective stiffness used in these analyses. These methods are evaluated on the basis of how accurately the initial period, building displacements, story accelerations and load distribution are simulated. The results of this study include recommended methods for application of elastic, response-spectrum analysis for seismic design of concrete walls. |
