Review of Methodologies for Displacement Checks in Modern Seismic Design Codes

This review paper discusses the procedures for evaluating design displacement given in various codes from seismically prone countries around world (the United States, New Zealand, Chile, Japan, Greece, Italy, Iran, India, Turkey, and Romania). The limit displacements corresponding states are also presented analyzed this study besides importance class factors considered selected seismic codes. A presentation of behavior necessary value action is shown study.
