Assembled special-shaped-column-structured loading device and test method thereof

Abstract

The invention relates to an assembled special-shaped-column-structured loading device and a test method thereof. The assembled special-shaped-column-structured loading device comprises a left-side door frame, a right-side door frame, a pressure beam, a column support seat, a lateral support, an actuator loading head, a rolling friction support seat, a displacement meter and a beam end fixing device for a special-shaped column body, wherein the displacement meter is used for collecting displacement of the special-shaped column body; the left-side door frame is parallel with the right-side door frame; a door frame comprises a door frame beam and a door frame column; two ends of the pressure beam are connected with the door frame beam through bolts; one end of the actuator loading head is connected with an actuator, and the other end of the actuator loading head is connected with the special-shaped column body; the displacement meter is fixed a vertical upright pillar connected with a table seat; the door frame beam is fixedly arranged on the table seat; the column support seat is fixedly arranged on the table seat. The assembled special-shaped-column-structured loading device and the test method have the beneficial effects that the operation is simple and convenient, the mounting is easy, and the loading test can be carried out on L-shaped, T-shaped and cross-shaped assembled special-shaped columns with different cross sections; the test data is accurate, and the measurement precision is high.

Description

technical field [0001] The invention relates to a loading test of a prefabricated steel pipe concrete special-shaped column, in particular to a loading device for a prefabricated special-shaped column structure and a test method thereof. Background technique [0002] In the prefabricated concrete-filled steel tube special-shaped column structure, the mechanical performance of the joints and column joints directly determines the overall performance of the structure. Therefore, joints and joints with reasonable stress and convenient construction are the key to the design of prefabricated concrete structures and determine the structural form. An important factor affecting the promotion and application. The prefabricated special-shaped column structure refers to the structural form in which the special-shaped column is prefabricated in a factory and transported to the construction site for assembly. The prefabrication rate of this structural system is high, but the connection s...

AI Technical Summary

Problems solved by technology

The prefabrication rate of this structural system is high, but the connection structure of the joints is relatively complicated and the construction is difficult. It is difficult to ensure that it is completely equivalent to the cast-in-place special-shaped column structure. More structural seismic tests are needed to verify the reliability of its structure.
