Vertical component safety analysis method based on catenary

Abstract

The invention discloses a vertical component safety analysis method based on the catenary. The method is characterized in that a refined model and an overall model of a structure are coupled to obtain a numerical model, visual and dynamic numerical simulation can be provided for the collapse type of a high-rise structure, and the development condition of a horizontal component catenary mechanism in the component detaching position is analyzed under a certain accidental condition and disaster condition to carry out anti-continuous-collapse design. Compared with the prior art, the method has the advantages that the structure analysis process is simple, working efficiency is high, full and reliable parameters are provided for anti-collapse design of a key component, visual, quantitative and accurate component safety redundancy is obtained, and the method is particularly applicable to safety analysis of anti-collapsing design of the high-rise structure.

Description

technical field [0001] The invention relates to the technical field of structure anti-collapse design, in particular to a catenary-based safety analysis method for vertical components. Background technique [0002] The safety of structures is the primary problem of structural design, and the collapse of buildings has always been the main source of casualties and equipment damage. With the deepening of urban modernization, there are more and more high-rise office buildings and landmark buildings, and their safety and collapse resistance are also highly valued. In many earthquake damage investigations, it is also found that the main performance of high-rise building structure damage and even collapse under the action of a large earthquake is brittle shear failure or buckling failure of columns and walls. Once the vertical components are damaged, it is very likely to cause the structure to overturn, and eventually lead to its overall collapse, resulting in a large loss of life...

AI Technical Summary

Problems solved by technology

However, the enhanced ductility of horizontal members may cause insufficient safety of vertical members, leading to a further expansion of the scope of structural collapse

[0004] The evaluation of the anti-collapse ability of the structure in the prior art is mainly aimed at the whole structure, but for the structure, especially the structure that has been designed for anti-collapse, whether the relative strength and safety of the vertical and horizontal components are reasonable has not been paid attention to and considered.
