Abstract

The invention belongs to the technical field of civil engineering test devices, discloses a structure multi-dimensional loading test system considering real and complex boundary conditions, and solves the problem that the stress state of existing quasi-static and quasi-dynamic loading equipment in a model test of a civil engineering structure is significantly different from the actual situation. The structure multi-dimensional dynamic loading test system considering the real and complex boundary conditions comprises a main machine part, a base part, a hydraulic power source and a control system. The system can better and more accurately simulate the load borne by the structure in a real working environment, realizes spatial six-degree-of-freedom multi-dimensional load loading, can provide more real experimental data with higher practical value for the damage research of reinforced concrete materials, components and structures under the action of earthquakes, the research result is helpful for researchers to further reveal the failure mechanism of the reinforced concrete structure, put forward corresponding failure criteria and develop a corresponding anti-seismic design method.

Description

technical field [0001] The invention relates to a structural multi-dimensional loading test system considering real complex boundary conditions, and belongs to the technical field of civil engineering test devices. Background technique [0002] The damage and collapse of engineering structures in earthquakes is the main cause of economic losses and casualties. It is of great significance to reveal the earthquake damage mechanism of engineering structures and propose effective seismic design methods to reduce the seismic response of structures and ensure the safety of people's lives and property. Due to the complexity of the seismic mechanism and the seismic performance of structures, people have to carry out seismic model tests to supplement the insufficiency of theoretical analysis. However, in the existing seismic model tests, there are significant differences between the stress state of structures or components and the actual situation. In the structural model seismic t...

However, in the existing seismic model tests, there are significant differences between the stress state of structures or components and the actual situation

In the structural model seismic test method, there are serious size effects caused by model scaling; and the component test that people want to study and describe the failure form and mechanism in detail cannot simulate multi-dimensional loading and real complex boundary conditions in earthquakes
