Test device for service performance of reinforced column under load and environment coupled action

Abstract

The invention relates to a test device for service performance of a reinforced column, in particular to be suitable for occasions for researching mechanical property and residual bearing capacity of the reinforced column under a load and environment coupled action, belonging to the field of structure durability tests. The test device comprises the reinforced column, a prepared hole arranged on the reinforced column, a tensile rib, a fixing member, an anchoring member, a loading support, an environment simulation box and a test machine, wherein the tensile rib is penetrated and inserted into the prepared hole of the reinforced column, the fixing member is fixed at one end of the tensile rib, the anchoring member is fixed on the other end of the tensile rib, the middle of the loading support is provided with a through hole, the pore diameter of the through hole is more than the diameter of the fixing member and the anchoring member, and the fixing member and the anchoring member can be penetrated and inserted into the through hole of the loading support and are movably connected with the loading support relatively up and down.

Description

technical field [0001] The invention relates to a test device for the full-life service performance of a reinforced concrete column, which is especially suitable for studying the time-varying mechanical properties and residual bearing capacity of a reinforced concrete column under the coupled action of environment and load, and belongs to the field of structural durability tests. Background technique [0002] Concrete structures work under a certain load and are subjected to coupling effects of various factors such as hardening, penetration, freeze-thaw, and chemical erosion. A large number of concrete durability results under no load cannot reasonably reflect the actual state of the structure. . For half a century, accidents of premature failure and shortened service life of concrete structures due to insufficient durability have been increasing, especially when major projects such as dams, roads, bridges, ports, and high-rise buildings are destroyed before reaching the des...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the load effect cannot be considered in the current test device, the influence of the service environment cannot be considered due to its large volume, the remaining bearing capacity of the component cannot be measured without unloading, and the full life of the column under the coupled action of the environment and load cannot be tested. In view of the shortcomings of service performance, provide a test device for the service performance and residual bearing capacity of reinforced concrete columns with simple structure, convenient operation, small size, no test space, and consideration of environment and load coupling.
