Abstract

The invention provides a device for out-of-plane stability bearing capacity testing of an arched steel structure. The device comprises a loading frame, a loading hemisphere, a U-shaped bidirectional hinge, a reinforcing beam, a ground beam and a jack. One end of the loading hemisphere is connected to the arched steel structure, the other end of the loading hemisphere is connected to the loading frame, one end of the U-shaped bidirectional hinge is connected with the lower end of the loading frame, the other end of the U-shaped bidirectional hinge is connected with one end of the reinforcing beam, the jack acts on the middle position of the reinforcing beam, and the other end of the reinforcing beam opposite to the U-shaped bidirectional hinge forms a hinged support together with the ground. The two ends of the arched steel structure are connected with the ground beam. The device not only has accuracy and reliability in testing, but also enables the tested arched steel structure to be freely subject to out-of-plane displacement, torsional deformation, in-plane displacement and in-plane rotation, and the out-of-plane instability characteristics of the arched steel structure are reflected genuinely.

Description

technical field [0001] The invention belongs to the technical field of arched steel structures, and in particular relates to an out-of-plane stability bearing capacity test device for arched steel structures used for testing the out-of-plane stability of arched steel structures. Background technique [0002] With the development of the national economy, there is a strong demand for building more and larger sports, leisure, exhibitions, airports, hangars and other large-space and super-large-space buildings. This kind of building form is generally a space arched steel structure, and the structure type can be divided into grid frame (light steel), space truss (heavy steel) and so on. These buildings usually have the characteristics of large span, unique shape, complex stress and regional symbolic significance after completion. [0003] At present, the research scope of the out-of-plane stability performance of this long-span arched steel structure mainly focuses on two aspect...
