Test method and test device of anti-seismic support hangers for building electromechanical pipeline facility

Abstract

The invention provides a test method and test device of anti-seismic support hangers for a building electromechanical pipeline facility. According to the method, a low-cycle reciprocating cyclic loading mode controlled by a displacement index is adopted to carry out loading test on a single set of anti-seismic support hanger, and a specific displacement loading system is determined by a monotonous horizontal pushing test result of the anti-seismic support hangers of the same specification; anti-seismic performance evaluation indexes such as the ultimate bearing capacity, the ultimate displacement, the yield displacement, the rigidity degradation coefficient and the ductility coefficient of the anti-seismic support hanger and a determination method of the anti-seismic performance evaluation indexes are provided. According to the test method and test device of the invention, the requirements of different types of anti-seismic support hangers in the current domestic market on test methods can be met, the technical blank of testing the anti-seismic performance of door-shaped support hangers is filled up, the defects of two fixed test loads (2.25 kN and 9kN) in the prior art are made up, the adverse effects of simultaneously testing four sets of anti-seismic support hangers on test results are avoided, the test installation procedure is simplified, the test efficiency is improved, and the accuracy and scientificity of the anti-seismic performance test method of the support hangers are effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic performance testing of non-structural components used in building electromechanical pipeline facilities, and in particular relates to a test method and test device for antiseismic supports and hangers used in building electromechanical pipeline facilities. Background technique [0002] The anti-seismic support and hanger is an anti-seismic support facility firmly connected with the building structure composed of anchors, reinforced suspenders, anti-seismic connecting members and anti-seismic bracing. The displacement and vibration of the auxiliary mechanical and electrical facilities can reduce or prevent the occurrence of secondary disasters as much as possible, so as to make the auxiliary facilities available after the earthquake and reduce casualties and property losses. is of great significance. The existing domestic standard "General Technical Conditions for Building Seismic Supports an...
