REVIEW OF THE DEVELOPMENT OF THE CAPACITY SPECTRUM METHOD

摘要: The Capacity Spectrum Method (CSM), a performance-based seismic analysis technique, can be used for variety of purposes such as rapid evaluation large inventory buildings, design verification new construction individual an existing structure to identify damage states, and correlation states buildings various amplitudes ground motion. procedure compares the capacity (in form pushover curve) with demands on response spectra). graphical intersection two curves approximates structure. In order account non-linear inelastic behavior structural system, effective viscous damping values are applied linear-elastic spectra similar spectra. paper summarizes development CSM from 1970s present includes discussions modifications presented by other researchers, well recommendations author.
