Description

Technical Field

The invention belongs to the technical field of loading test application equipment, and particularly relates to a constraint support for changing a test loading direction of a test component.

Background

The restraining support is an essential and important component in component or structural testing. Conventional test restraint mounts typically employ reinforced concrete piers and large steel beams to secure the test members together.
