Testing apparatus of dynamic response of filler wall under combustible gas explosion

Abstract

Disclosed in the invention is a testing apparatus of a dynamic response of a filler wall under combustible gas explosion. The testing apparatus comprises a reinforced concrete room (3) without rear side wall and a reinforced concrete frame (5) fixedly connected to the rear side wall of the room (3). A testing brick wall (8) is prefabricated on the frame (5). An explosion venting hole (1) is formed in a front side wall of the room (3) and is filled with an explosion venting material. A plurality of pressure sensors (2) are arranged at the inner side of the front side wall of the room (3). Besides, a displacement meter (16) is arranged at the outer side of the testing brick wall (8); and the pressure sensors (2) and the displacement meter (16) are in signal connection with a data acquisition unit (6). An igniting head (4) is arranged inside the room (3); and a combustible gas source connected with the room (3) is also arranged outside the room (3). According to the testing apparatus, a real combustible gas explosion load can be used for loading the filler wall.

Description

technical field [0001] The invention belongs to the technical field of anti-explosion test and research equipment for building structures, in particular to a test device capable of performing dynamic response of a filling wall under the action of combustible gas explosion. Background technique [0002] Masonry structures are prone to brittle fracture damage under the action of combustible gas explosion loads. Under the action of explosive impact loads, the fragments formed by the fracture will be projected at high speed, and these high-speed projected fragments will cause damage to personnel and facilities inside and outside the building. great harm. [0003] However, since the history of gas application in civil buildings in my country is not long, it has not attracted too much attention, and the development of related research is relatively late. At present, most of the researches on gas explosions in our country are aimed at the safety of factories that produce or come i...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the problems existing in the prior art are: the loading test of the infill wall cannot be carried out with the real combustible gas explosion load, and the accurate parameters such as the anti-explosion performance and failure mode of the infill wall cannot be obtained.
