Embodiment Construction

[0027] The present invention will be described in detail below in combination with specific embodiments.

[0028] The invention relates to an anti-seismic performance test device of a completely asymmetrical cross-shaped steel concrete joint. The test object is a cross joint component, which is suitable for the anti-seismic performance test device of the component and can effectively clamp the test object.

[0029] The device includes a reaction wall 1, which is "inner" close to the reaction wall 1 and "outer" far away from the reaction wall 1. The cross node components are arranged vertically perpendicular to the reaction wall 1 . The top side of the cross node member is connected to the reaction wall 1 through the No. 1 servo actuator 4 which is perpendicular to the reaction wall 1 and horizontal, and the top surface of the cross node member is connected to the No. 2 door type reaction frame 3 set above it The No. 1 sliding support 17; the bottom side of the cross node memb...

Abstract

The invention relates to a device for testing the seismic performance of a fully asymmetric cross-shaped steel concrete joint. The device includes a reaction wall. A cross-shaped joint member is perpendicular to the reaction wall and vertically arranged. The side of the top end of the cross-shaped joint member is connected to the reaction wall through a horizontal first servo actuator perpendicular to the reaction wall. The top surface of the top end of the cross-shaped joint member is connected to a first sliding support on a second gate-type reaction frame arranged above the cross-shaped joint member. The side of the bottom end of the cross-shaped joint member is connected to the reaction wall through a horizontal second servo actuator perpendicular to the reaction wall. The bottom surface of the bottom end of the cross-shaped joint member is connected to a second sliding support arranged on the ground. The bottom surface of the outer end of the cross-shaped joint member is connectedto the ground through a vertical connecting rod. The inner end of the cross-shaped joint member is fixed to a first gate-type reaction frame arranged on the inner side of the cross-shaped joint member. The cross-shaped joint member is constrained at multiple points. Boundary conditions required for test can be provided, and the support reaction of the member can be accurately measured.

Description

technical field [0001] The invention relates to an anti-seismic performance test device, in particular to a completely asymmetric cross-shaped steel concrete joint anti-seismic performance test device. Background technique [0002] The height of modern buildings is increasing, the building functions tend to be comprehensive and diverse, and the structure shapes are becoming more and more complex. Most high-rise and ultra-high-rise buildings mainly adopt composite structures and hybrid structural systems, and some new structural systems are constantly emerging. The composite structure of section steel and rod concrete is a structural form superior to steel structure and reinforced concrete structure. It not only inherits the respective advantages of steel structure and reinforced concrete structure, but also overcomes the shortcomings of both, and makes full use of the materials of steel and concrete. It not only has the technical advantages of steel structure but also has t...
