Description
technical field [0001] The invention belongs to the technical field of structural seismic design, in particular to a high-stability method and equipment for calibrating a design response spectrum based on an improved differential evolution algorithm. Background technique [0002] The elastic response spectrum theory is the basic theory of seismic design at this stage. The design response spectrum is used to evaluate the seismic action that the building structure may experience during its reference period. Regulation. The seismic design response spectrum is an important basis for seismic design, and it is characterized by the characteristic parameters of the design spectrum and plays a key role in determining the earthquake action. The calibration of the design response spectrum is to determine the characteristic parameters of the seismic response spectrum in a prescribed form, which is used to control the shape and platform value of the design spectrum. Therefore, the cali...
