The invention discloses a novel test supporting seat used for beam-column joint testing. The supporting seat includes a horizontal slide supporting seat, a fixing supporting seat and a detachable column hinge; the fixing supporting seat includes a base plate fixed on a counterforce foundation, a horizontal force bearing plate is arranged on the top of the base plate, and a linear guide rail arranged on the top of the base plate; the horizontal slide supporting seat includes a sliding plate in vertical arrangement and slide blocks fixed at the bottom of the sliding plate; the slide blocks are slidingly connected to the linear guide rail; one side of the sliding plate is detachably connected to the column hinge, and a load dowel bar is arranged between the other side of the sliding plate andthe horizontal force bearing plate; and one end of the load dowel bar is fixedly connected to the sliding plate, and the other end of the load dowel bar passes through the horizontal force bearing plate and is connected to a load sensor. The supporting seat can be used for accurately determining horizontal axial force generated when a beam-column joint sample is under vertical load, and can alsobe used for accurately determining arch effects and cable effects when the beam-column joint sample is fixedly connected to a beam end.
Description
technical field [0001] The invention relates to the technical field of civil engineering structure tests, in particular to a novel test support for column-beam joint tests. Background technique [0002] In the prefabricated frame structure, the beam-column joint connects the prefabricated beam-column into a whole, and the joint joint plays the role of load transmission and seismic energy dissipation. The connection part of the stressed member occupies a pivotal position in the fabricated frame structure. Prefabricated concrete joints can improve the overall stability of the structure. At present, in the mechanical performance test of column-beam joints, it is impossible to accurately measure the horizontal axial force generated by the column-beam joint specimens under the vertical load, and it is also impossible to accurately measure the arch of the column-beam joint specimens when the beam ends are fixed. effect and cable effect.
