Description

technical field [0001] The present application relates to the technical field of architectural structure design, in particular to a structural stability analysis method, system, terminal and medium under vertical earthquake action. Background technique [0002] According to code design requirements, vertical seismic analysis is usually required for long-span structures or structures with overhangs. [0003] In related technologies, the vertical seismic analysis method mainly includes: method 1, performing vertical seismic analysis on the overall structural model of the building. Method 2: Establish a local structural model separately for the long-span structure and overhanging structure in the building, and conduct vertical seismic analysis on the local structural model. [0004] Among them, method one is difficult to meet the standard that the participation quality coefficient is greater than 90%, and it is difficult to meet the calculation requirements. The second method...
