Embodiment Construction
[0027] like Figure 1-3 As shown, the device for imposing lateral constraints on the test member includes a loading device 1 and a restraint device 2; the loading device 1 has at least one set, which is arranged on one of the longitudinal sides of the test member 3; wherein, each set The loading devices 1 are vertically arranged in parallel at intervals, and each loading device 1 is set correspondingly to the nodes of the test member 3; the free ends of the loading devices 1 are fixedly connected to the test member 3 to apply lateral loads to the nodes; There is one group of restraining devices 2, which are arranged at intervals on the lateral side of the test member 3; and the free ends of the restraining devices 2 are fixedly connected to the test member 3 to restrain the longitudinal displacement of the nodes.
[0028] In this embodiment, the test member 3 is a reinforced concrete frame structure member, including a column 3.1 and a frame beam 3.2 connected between adjacent...

The invention provides a device applying lateral restraint to a test member and a test method. The device applying lateral restraint to the test member comprises at least one group of loading devicesand one group of restraint devices, wherein the at least one group of loading devices are arranged on one longitudinal side surface of the test member; each group of loading devices are arranged in parallel at intervals in a vertical direction; each loading device corresponds to nodes of the test member; the free ends of the loading devices are fixedly connected to the test member and are used forapplying transverse loads to the nodes; the one group of restraint devices are arranged on one transverse side surface of the test member at intervals in a transverse direction; and the free ends ofthe restraint devices are fixedly connected to the test member and are used for restraining the longitudinal displacement of the nodes. The device and test method solve the technical problems that theaccurate reappearance of boundary conditions are impossible in the traditional experiment, and the accuracy and credibility of test results are low.
Description
technical field [0001] The invention relates to the field of experimental mechanics, and specifically relates to a device and a test method for imposing lateral constraints on test components. Background technique [0002] Due to the huge size of building structures, it is difficult to carry out full-scale structural tests due to the constraints of economy and test environment. Generally, the key parts of the structure or the parts with complex and concentrated forces are selected for research. In this way, selecting components in the structure for mechanical performance research inevitably needs to restore the real force state of the component boundary, that is, the reproduction of component boundary conditions. [0003] There are 6 degrees of freedom in the actual boundary of the structural member, but the current technical limitations cannot guarantee that the 6 degrees of freedom are constrained and loaded at the same time; the current conventional method is to consolida...
