Problems solved by technology

[0003] The prototype of high-rise RC frame structure has the disadvantages of large size, high cost, and long time consumption, and it is difficult to carry out experimental research on the original size. At this time, it is particularly important to establish a scaled-down model of high-rise RC (Reinforced Concrete) frame structure

Embodiment Construction

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention. .

[0044] The design method of the scale model has the following steps:

[0045]Step 1. Before establishing a scale model of the prototype of the high-rise RC frame structure under the action of the far-field explosion load, analyze the mechanism of the far-field explosion and simplify the high-rise RC frame structure:

[0046] Such as figure 1 Among them, the explosion of explosives in the air can cause different degrees of damage and damage to the surrounding targets. The destructive effect of air explosion is not only related to the equivalent, but also related to the distance between the target and t...

Abstract

The invention provides a reduced-scale model design method of a high-rise RC frame structure. The reduced-scale model design method is used for predicting the far-field explosion damage effect of thehigh-rise RC frame structure; a high-rise RC frame structure similarity model under the action of a far-field blast load is established by adopting a similarity theory so as to judge the damage effectof the prototype; when destructive tests such as damage research of a high-rise RC frame structure under the action of a far-field blast load are carried out, the introduction of model tests can reduce the experiment cost, and the method has the advantages of easiness in development, high feasibility and the like.

Description

technical field [0001] The invention belongs to the field of civil engineering structural engineering explosions, and in particular relates to a design method for a scale model of a high-rise RC frame structure, which is used for predicting the damage effect of the high-rise RC frame structure in a far-field explosion. Background technique [0002] With the continuous development of human society, the requirements for high-rise buildings are developing in the direction of larger volume, higher height and newer shapes, so various new high-rise building structural systems are born. In recent years, a large number of explosion accidents have occurred and caused serious damage to high-rise buildings, such as: the oil tank truck explosion in Wenling, Zhejiang on June 13, 2020, the explosion in Tianjin Binhai New Area in 2015, and the explosion in a chemical plant in Changzhou, Jiangsu. The explosion, and the shock wave of the explosion caused serious damage to the surrounding hig...
