Self-resetting assembly type bamboo-joint-shaped round bar energy dissipation rod

Abstract

The invention discloses a self-resetting assembly type bamboo-joint-shaped round bar energy dissipation rod. The self-resetting assembly type bamboo-joint-shaped round bar energy dissipation rod comprises a core part (1), a restraining part (2) and a positioning bolt (3), wherein the core part is composed of an energy dissipation section (1-1), a self-resetting section (1-2), a connecting sleeve (1-3) and a clamping section (1-4), the inner diameter of the restraining part (2) is greater than the outer diameter of the connecting sleeve (1-3), so that a micro gap exists between the restraining part and the connecting sleeve, Under large and medium earthquakes, the uniform-section part (1-1-1) in the middle of an energy dissipation section generates plastic deformation to dissipate energy, the bamboo joint part (1-1-3) keeps elasticity and limits lateral displacement, the self-resetting section (1-2) can achieve the self-resetting function after the earthquakes, the restraining part (2) can prevent a core part from generating low-order buckling damage, the energy dissipation section and the self-resetting section are connected through a bolt, the purpose of replacement after the earthquakes can be achieved, and the cross sections and the length sizes of the energy dissipation section and the self-resetting section can be variously selected. The functions of energy dissipation and shock absorption, self-resetting after the earthquakes, replaceability after the earthquakes and flexible combination are achieved.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to an anti-buckling restraint support for reducing the seismic response of an engineering structure. Background technique [0002] China is an earthquake-prone area. Under the action of strong earthquakes, houses and buildings usually collapse, causing serious secondary disasters and causing huge losses of life and property to the people. In order to reduce the damage to structures caused by earthquakes, researchers The concept of energy dissipation and shock absorption is proposed. The idea is to install auxiliary energy dissipation devices in the building structure to consume the huge energy brought by the earthquake, so that the main structure of the building can be effectively protected and avoided. Serious damage. Among all kinds of energy-dissipating and shock-absorbing devices, metal dampers are favored by scholars and engineers for their excellent energy-dissipating capacity, ...
