One-way clamp force transmission low-prestress self-resetting support

A one-way clamp force transmission low-prestress self-resetting support is characterized in that the one-way clamp force transmission low-prestress self-resetting support is composed of an energy consumption outer cylinder and a self-resetting system which are only subjected to tensile yielding, and the energy consumption outer cylinder is formed by connecting a high-strength steel bar clamp one-way force transmission system, an energy consumption soft steel bar and a right end plate in series. The self-resetting system comprises an inner cylinder, a middle cylinder and a pre-stress resettingelement, wherein the pre-stress resetting element is formed by connecting a post-tensioned pre-stress tendon and an elastic spring arranged at the anchoring end of the post-tensioned pre-stress tendonin series. Complete restoration after the supporting earthquake can be realized only by applying a small amount of prestress; a stable and reliable key component one-way force transmission mechanismcan be realized without com
