平面双向多功能加载试验装置研制与应用
Development and application of planar bi-directional multi-functional element tester
摘要
Abstract
This study presents an experimental investigation on two-dimensional basic elements with panel testers.Accurate nonlinear constitutive laws of new materials and new structures were proposed,so that popularization and application of new materials and new structures in engineering can be accelerated.Based on the investigation and analysis of the relevant testers in America,Japan,Germany and other countries,a simple panel tester-planar bi-directional element tester(PBET),has been developed,which is composed of a self-balancing reaction frame system,a loading system that can effectively weaken the edge constraints,a control system that can realize complex loading conditions and paths,and a multi-functional measurement system.By using PBET,one-directional tensile test of reinforced UHPC element,two-directional tensile test of non-reinforced UHPC element,a series of tests,including combined tension-compression test of non-reinforced UHPC element,combined tension-compression test of single steel plate concrete element and combined tension-compression test of double steel plate concrete element,were completed.The test results show that tests can be conducted by PBET on various structural elements such as UHPC,reinforced UHPC,single steel plate-concrete and double steel plate-concrete structure,with loading conditions including uniaxial tension,biaxial tension,and biaxial tension-compression coupling.The sequential loading,proportional loading and loading path conversion functions can be realized.Thus,PBET can provide support for the research on the 1D/2D basic mechanical properties and constitutive relationship of new materials such as UHPC and ECC,as well as new structures such as steel plate-concrete structures.关键词
