Dear Chayma El Mtili

Pushover analysis is a static procedure that uses a simplified nonlinear technique to estimate seismic structural deformations. The structure is “pushed” again until the second weak link is discovered. This process continues until a yield pattern for the whole structure under seismic loading is identified.

Nonlinear time history analysis is known for simulating a structured behavior under severe earthquakes more properly than other methods. To ensure valid results comparison, a ground acceleration time history is used for both linear and nonlinear time history analysis.

Pushover analysis allows for direct evaluation of the performance of the structure at each limit state. Time history analysis is the most reliable analysis method among all the nonlinear analysis methodologies.

To check the structure under earthquakes you need to use Nonlinear time history analysis, there are many software's to do this. SAP2000, Abaqus, Etabs, Opensees, OpenseesPy, etc. It depends on your ability in each software, but from my experience, Opensees is the accurate one while SAP is the easiest one to use.

SeismoStruct is excellent at pushover analysis and educational licenses are free.

Dear Timothy Huff

SeismoStruct is also available, but you need to know that educational licenses are limited. As I know T is limited. It is better to prepare a license or at least you can use a license from your institute.

You can refer pushover definitions under load & definition category in StaadPro.The help manual can be referred for assigning hinges and application of loads to the hinges of the building.

dear Timothy Huff

do you know which model is used in the FE program (SeismoStruct) for the pushover calculation? do they use the Aurucchio model?

Dear Chayma El Mtili

There are several material models and element types available in SeismoStruct. Indeed, one of the 20 material models available is the superelastic shape-memory alloy model proposed by:

Auricchio F., Sacco E. [1997] "A superelastic shape-memory-alloy beam," Journal of Intelligent Materials and Structures, Vol. 8, pp. 489-501.

Element types include force-based and displacement-based inelastic fiber-based elements, plastic hinge elements, Bouc-Wen bearing elements, friction-pendulum system elements, etc.
