Description

technical field [0001] The invention relates to a dynamic and static multifunctional test servo loading system, which belongs to the technical field of civil engineering. Background technique [0002] In recent years, earthquakes have occurred frequently, and secondary disasters such as large earthquakes, intensive earthquakes, and accompanying or triggered tsunamis, debris flows, etc. will cause serious damage to sea and land infrastructure engineering structures; in addition, accidental events such as traffic accidents and terrorist attacks will also damage infrastructure structural components. Causes damage and destruction, and is difficult to repair, resulting in significant economic losses and threatening life safety. There is an urgent need for a simulation test platform that can truly simulate the mechanical behavior of the structural system and structural components under the action of earthquakes, tsunamis, vehicle and ship collisions, explosions, and impacts.

Problems solved by technology

However, the existing structural test system cannot simulate the nonlinear dynamic behavior of large structural members in a multi-hazard environment, especially for the multi-dimensional dynamic fast hysteretic loading of large structural members.

[0003] Most of the existing loading systems can perform static tests such as static reciprocating loading tests and pseudo-dynamic tests, but the installation and disassembly are complicated, and they cannot simulate various boundaries and loading conditions of structural components in the actual structure
