Risk-oriented aseismic design spectrum construction method based on single-point anchoring and multi-point anchoring

The invention relates to a risk-oriented aseismic design spectrum construction method based on single-point anchoring and multi-point anchoring, belongs to the technical field of earthquake engineering and disaster prevention and reduction engineering, and aims to solve the problems that an existing consistent danger aseismic design spectrum only considers the earthquake risk of a site, does not consider the earthquake vulnerability of a structure, and does not consider the earthquake risk of the site. According to the risk-oriented aseismic design spectrum construction method based on single-point anchoring and multi-point anchoring, the problems that in the prior art, the risk-oriented aseismic design spectrum is difficult to obtain consistent and socially acceptable target collapse risks are solved, the earthquake risk of a site and the earthquake vulnerability of a structure are considered at the same time, and the risk-oriented aseismic design spectrum is constructed through single-point anchoring and mu
