Abstract

The invention discloses an adjustable and detachable type large eccentric compression column testing device and method. The device comprises a concrete column test piece, disassembly steel plates, loading steel plates, a pressure loading unit, a displacement testing unit, a strain gage, a static signal analysis system and a computer, wherein the concrete column test piece is positioned between theupper and lower loading steel plates of the pressure loading unit, the disassembly steel plates are mounted at two ends of the concrete column test piece, and the loading steel plates are mounted atthe other ends of the disassembly steel plates. The disassembly steel plates and the loading steel plates are mounted at two ends, the fixation effect of a bracket loading end is realized, the steel plates are detachably recycled, the testing device has the testing benefits of energy conservation, emission reduction and costing saving, and tested test pieces come from real working conditions, so that the testing data are reliable and true, and the range of application is wide.

Description

technical field [0001] The invention belongs to the field of concrete construction, in particular to an adjustable and detachable large eccentric compression column testing device and method. Background technique [0002] When carrying out tests on the bearing capacity of eccentric compression columns in the laboratory, cast corbels are used to provide eccentricity by increasing the loading surface. The corbel plays the role of providing loading eccentricity, and the steel bars in the corbel are more dense, and the concrete column specimen loses its use value after being damaged, which causes waste of both steel bars and concrete. Since most of the real frame columns in the project are not loaded with corbels, with the increasing number of demolition projects, rational use of the demolished components for testing can achieve energy saving and emission reduction, because the demolished components are components under real working conditions , rather than the components maint...
