Repeated loading test device for combined shear wall test piece

Abstract

The invention discloses a repeated loading test device for a combined shear wall test piece, and belongs to the technical field of loading experimental apparatuses. The repeated loading test device of the combined shear wall test piece comprises a steel structure test bench, a horizontally fixed screw rod, a nut, a test piece backing plate and a vertically fixed screw rod, wherein the steel structure test bench is fixed on the ground through the vertically fixed screw rod, the combined shear wall test piece is installed on the steel structure test bench in an inverted mode, the test piece is fixed through the horizontally fixed screw rod, and the repeated loading is applied to the combined shear wall test piece along the horizontal direction. The device disclosed by the invention can fully stimulate a shear performance test of the test piece under the action of repeated loading, analyzes the shear deformation capability of the test piece, and can analyze the friction generated by the shift between concrete and steel and between the concrete and the concrete in the combined shear wall test piece. The device disclosed by the invention is easy to manufacture and convenient to use, is wholly connected by bolts and is convenient to assemble and disassemble, the space is saved and the storage is convenient.

Description

technical field [0001] The invention relates to a repeated loading test device and a manufacturing method of a combined shear wall test piece, which belong to the energy consumption shock absorption technology of building structures. Background technique [0002] Traditional shear wall tests apply low-cycle repeated loads to specimens through repeated loading test devices to simulate the stress and deformation characteristics of structures or components in reciprocating vibration during earthquakes, and study the bearing capacity, stiffness, ductility, hysteresis performance and energy dissipation capacity. [0003] However, traditional reloading devices have certain limitations. With the rapid development of large complex high-rise buildings, steel-concrete composite shear walls are widely used in high-rise buildings as a new type of composite shear walls with excellent seismic performance. With the deepening of the research, there are more and more studies on the perform...
