Title: Multi-modal performance-based anti-seismic design method based on performance bispectrum
Inventor: LIU WENFENG
IPC: G06F17/50
Filed: 2018-10-27
Abstract: The present invention relates to the technical field of anti-seismic design, and in particular relates to a multi-modal performance-based anti-seismic design method based on a performance bispectrum. The method is used for anti-seismic design directly based on a quantified performance level. First, a single-degree-of-freedom elastic-plastic structural system of a performance bispectrum is artificially assumed and is enabled to be equivalent to a standard single-degree-of-freedom elastic-plastic structural system by adjusting a performance displacement angle ρ obj-m (d) of a structure top layer and second stiffness of a double-broken-line elastic-plastic model, thus obtaining a structural anti-seismic response effect at an anti-seismic performance level. The performance level based anti-seismic design method of the present invention takes a final damage state as a basis of anti-seismic design; therefore, whether an earthquake exceeding the seismic fortification intensity (a ground motion parameter) occurs, the anti-seismic performance of a structure can be controlled. Obviously, the patent for invention of the present application is more scientific than traditional performance-based anti-seismic design based on the seismic fortification intensity (a ground motion parameter), and can control the anti-seismic behavior of the structure.
