Using the Pushover Analysis add-on for RSTAB 9, you can analyze the seismic actions on a particular building, and thus assess whether the building can withstand an earthquake. The Pushover Analysis add-on allows you to analyze the deformation behavior of buildings subjected to a seismic action.
The capacity curve, which represents the nonlinear structural properties of a building, is calculated by applying a horizontal load distributed over the height and increasing it gradually. This curve is then compared to the seismic action, based on extensive libraries and the method specified in Eurocode 8, to determine the target displacement. The add-on provides you with the intuitive input and allows you to consider nonlinearities in irder to achieve realistic design.
