Yield displacement charts for performance-based seismic design

Abstract A new tool for seismic design is presented, called Yield Displacement Charts (YDC). As with its predecessors, the Point Spectra (YPS) and Frequency (YFS), YDC concept takes advantage of simple features yield displacement ( u y ), to use in a performance-based instead force-based period-dependent approach. self-contained comprehensive approach YPS YFS enabling novel aspect be introduced: multi-performance objective that only depends on location structure designed. Once chart has been calculated particular place, it can used preliminary any structure. For given value displacement, are obtained from Chart. The suitability methodology proposed illustrated by means case study concrete bridge pier.
