Abstract

A loading device applicable to a space specially-shaped column node test comprises a specially-shaped column structure of a test node, wherein the specially-shaped column structure of the test node is arranged in a loading device composed of a reaction force wall, a ground groove, a column top reaction force steel frame, a beam end reaction force steel frame and an electro-hydraulic servo actuator. A rolling shaft spherical hinge device is arranged below the column top reaction force steel frame, and a hydraulic jack is arranged on the lower portion of the rolling shaft spherical hinge device to be used for applying axial pressure to a specially-shaped column. A column bottom hinged support is arranged at the bottom of the specially-shaped column, and each beam end loading point of the beam end reaction force steel frame is provided with a beam end hinged support. The electro-hydraulic servo actuator is installed on the top of the specially-shaped column. According to the loading device applicable to the space specially-shaped column node test, a column end loading mode is adopted to coordinate with the whole set of loading device to form a bi-directional repeated loading force-bearing condition. A force-bearing mechanism coincides with an actual situation, and loading requirements of the space specially-shaped column structure node test with different sections such as T-shaped, L-shaped and cross-shaped can be met. Different-angle loading schemes can be achieved through adjustment of the position of the beam end reaction force steel frame.

Description

technical field [0001] The invention relates to a loading device suitable for joint tests of space special-shaped columns. Background technique [0002] The special-shaped column structure mainly replaces the traditional rectangular section column with T, L, Z, cross-shaped and other special-shaped columns. The usable area is increased, the architectural appearance is improved, and the use function is brought flexibility and convenience. It is a structural form that conforms to the development direction and trend of modern architecture. [0003] As the core part of the special-shaped column structure, the joint is very critical to ensure the good seismic performance of the frame as a whole; to make the overall structure have superior seismic performance, it is far from enough for the special-shaped column to have superior seismic performance. Therefore, the research on special-shaped column joints has become an urgent problem to be solved. [0004] At present, domestic and...
