The nonlinear static analysis algorithm of SeismoStruct has been implemented in the popular Italian structural design package: IperSpace v11.0. The developers of this program asked SeismoSoft to implement its accurate and very stable pushover algorithm inside their own software, in order to render the latter compatible with the requirements of modern seismic codes, where nonlinear analysis is explicitely foreseen and prescribed. Further details are available from the website of SoftLab (, the distributor of IperSpace.
