Abstract: A structure multi-dimensional loading test system considering real complex boundary conditions considering real complex boundary conditions comprises a main part of machine, a base part, a hydraulic power supply and a control system. The system can simulate the load borne by a structure in a real working environment better and more accurately, realize multi-dimensional loading of the structure with six degrees of freedom in space and provide more real and valuable experimental data for the research on damage of reinforced concrete materials, components and structures under the action of an earthquake, and the research results will help researchers further reveal the damage mechanism of reinforced concrete structures, put forward the corresponding damage criteria and develop the corresponding seismic design methods.

Abstract: The present invention belongs to the technical fields of civil engineering, smart material and health monitoring, and provides a viscous damper fluid viscosity monitoring device and method based on piezoceramic transducers, comprising piezoceramic transducers, wires, corks, a baffle and a viscous damper. When the fluid viscosity of the viscous damper changes, the energy dissipation of pressure waves during propagation in a fluid will change, and signals received by the piezoceramic transducers will change, so that the viscosity of the fluid in the viscous damper can be calculated by the amplitude change of the signals received. The device of the present invention has a simple structure and accurate monitoring results, and provides a simple and feasible method for real-time monitoring of fluid viscosity of viscous dampers in engineering.
