As the Developing countries move towards the implementation of Performance Based engineering philosophies in seismic design of civil structures, new seismic design provisions will require structural engineers to perform nonlinear analyses of the structures they are designing. These analyses can take the form of a full nonlinear dynamic analysis, or static nonlinear Pushover Analysis. Because of the computational time required to perform a full nonlinear dynamic analysis, the Pushover Analysis, if deemed applicable to the structure at hand, For this reason, there is a need for easy to use and accurate, nonlinear Pushover Analysis. The loads are increased until the peak response of the structure is obtained on a base shear Vs. roof displacement plot. From this plot, and other parameters representing the expected or design earthquake the maximum deformations the structure is likely to undergo during the design seismic event can be estimated.
