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...

Embodiment Construction

[0027] See attached figure 1 , the present invention carries out the security analysis of vertical component and strengthens the design according to the following steps:

[0028] (1) Determine weak parts and key vertical components

[0029] According to the conventional structural design of high-rise buildings, a simplified spatial bar system model is established by using general structural finite element software, and the structural design of high-rise buildings is analyzed as a whole by using the bar system model to determine the weak parts of the structure and determine the key vertical according to the structural system member.

[0030] (2) Establish a numerical model

[0031] According to the conventional structural design of high-rise buildings, the beam and shell elements in the explicit finite element software are used to establish the overall structural model, and then a certain weak part or key vertical component determined above is removed, and the entity in the e...
