Abstract

The invention discloses a joint loading method of a cantilever structure. The joint loading method specifically comprises the following steps: step 1, manufacturing a loading joint; step 2, manufacturing a loading device; step 3, mounting the loading device in the cantilever structure: placing the loading device on a horizontal hardened concrete floor, adjusting the thickness of a sole plate or the quantity of a base plate to adjust the height of the loading device, enabling a rolling column to be in exact contact with the lower part of a member necessary to be applied with a force, and thereby supporting the loading device in the cantilever structure. By virtue of the method, when the component is displaced, the component is still in the tangential direction of the joint, only the position of the contact surface but not the area of the contact surface is changed, so that the contact surface is guaranteed to be invariant, and the force application direction is still perpendicular to the component. The applied force is completely exerted on the component, and the force stressed by the component can be simply, conveniently and accurately measured.

Description

technical field

[0001] The invention relates to the field of experimental monitoring, and relates to a loading method for nodes in a cantilever structure. Background technique

[0002] When the load is applied to the end of the cantilever structure, when the load increases and the member deforms, the end of the cantilever member will displace around the fixed end, and the loading device is fixed, so it cannot keep the loading node and the member at all times during the loading process. Vertical, which will cause the position of the loading point to shift. Existing loading procedures such as figure 2 As shown, when the component changes from position a to position b, c or d under the action of force, the contact position between the loading point and the component changes due to the displacement of the component. The loading point and component contact point at position a are different from the contact point at position d, that is, the position of the action point of the lo...
