Title:
METHOD FOR CALCULATING ANTI-SEISMIC BEARING CAPACITY OF STRUCTURAL COMPONENT ON BASIS OF PERFORMANCE LEVEL
Document Type and Number:
WIPO Patent Application WO/2020/073364
Kind Code:
A1
Abstract:
A method for calculating the anti-seismic bearing capacity of a structural component on the basis of performance level, comprising: setting different performance levels by using the maximum interlayer displacement angle of a structure, and calculating structure vertex displacement at different performance levels; determining first mode of vibration displacement according to a first mode of vibration mass participation factor and the structure vertex displacement at different performance levels; obtaining the displacement of an equivalent single-degree of freedom system according to the first mode of vibration displacement; selecting ground motion suitable for a site to obtain a first mode of vibration earthquake impact factor at different performance levels; obtaining an earthquake impact factor according to a design response spectrum stipulated by anti-seismic specifications on the basis of the peak acceleration average of a plurality of ground motion at different performance levels; synthesizing structure earthquake actions at different performance levels under multiple modes of vibration; calculating bearing capacity. The anti-seismic bearing capacity of a structural component is calculated on the basis of performance level such that a method for anti-seismic design is more scientific.
