Abstract

The invention provides an out-of-plane air bag loading test device for a structural member. The device comprises a movable reaction frame, a reaction plate and an air bag, wherein the reaction plate and the movable reaction frame are connected through a plurality of metal pull rods to form a self-balancing reaction system; and the air bag is clamped between the structural member under test and thereaction plate. Through adoption of the device, the whole plane uniform loading of the structural member under test out of the plane is realized, and the wind load and earthquake action are simulatedtruly. A force-displacement curve can be measured without additional constraints on the structural member under test. The out-of-plane air bag loading test device can be widely applied to various engineering structural components, and has remarkable economical efficiency.

Description

technical field [0001] The invention relates to civil engineering structures, in particular to a test device for testing the out-of-plane stress performance of structural members. Background technique [0002] The out-of-plane test device for structural members has important practical significance for the study of out-of-plane mechanical properties of structural members. Existing test devices for testing the out-of-plane mechanical performance of structural members mainly include pseudo-static test devices, jack loading devices and shaking table test devices. [0003] Pseudo-static test devices and jack loading devices can carry out point load loading on structural members, but cannot apply uniform loads to the entire plane of structural members, and cannot truly simulate the effects of wind loads and earthquakes. Therefore, it is difficult to truly and effectively study the out-of-plane mechanical performance of structural members with pseudo-static test devices and jack l...
