For design purposes it has been common to consider that seismic excitations act in one direction at a time. Analytical studies over the past decade have indicated that this may not be an adequate assumption in certain circumstances. In particular, coupled torsional lateral response and response due to multiple components of base excitation can in some cases lead to significantly increased response. Many of these analyses have assumed linear elastic structural behavior. Studies that have used inelastic models indicate that such structures may behave much differently than structures that respond elastically. To help clarify this difference a series of experimental and analytical studies have been initiated focusing on both torsional response and response to multicomponent base excitation.
