Abstract

The technical scheme of the invention provides a brand-new elastic-plastic time-history analysis and displacement based seismic design method for a framework structure. Floor shear force calculated with a traditional inelastic displacement response spectrum and displacement based design method considering multiple vibration modes and earthquake action universality is taken as a check reference, thereby maximally reducing unsafe factors possibly caused by individual difference of earthquake waves. The invention aims to solve the technical problem in an existing displacement design method and is necessary to provide a design method capable of directly and effectively considering factors with important influences on displacement response of the framework structure and effectively controlling the displacement response of the framework structure under the specific earthquake action.

Description

technical field [0001] The invention belongs to the technical field of civil engineering construction, relates to an anti-seismic design method of a frame structure, and more particularly relates to an anti-seismic design method of a frame structure based on displacement. Background technique [0002] Displacement-based design method: A structural design method that can effectively control the displacement response of a structure under earthquake action. That is, the target limit of the displacement response of the structure under a specific earthquake is proposed, and the structure is designed according to a certain method based on the displacement target value, so that the displacement response of the structure under this specific earthquake, such as a large earthquake and a moderate earthquake, is close to the target displacement. [0003] Elastic-plastic time-history analysis method: Although there are still many problems to be further studied in the current elastic-pla...
