Abstract:
Capacity spectrum method is the primary method for nonlinear static analysis and the basic principles of this
method are introduced in this paper.The displacement-pattern-based pushover method is proposed and the capacity curve
of structure is obtained by this method.The equivalent single-degree-of-freedom method and equivalent linearization method
 is analyzed and MDOF system is converted into equivalent SDOF system.Based on the reciprocating pushover,equivalent
 system parameters are obtained and the seismic performance of the structure is evaluated.The displacement response
of structure can be determinate by elastic demand spectrum.A practical example of frame structure is used to validate this
methodology.The results can reflect the nonlinear behavior of the structure.
