Self-resetting assembly type bamboo-joint-shaped round bar energy dissipation rod
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.
一种自复位装配式竹节形圆棒耗能杆，包括核心部件(1)、约束部件(2)和定位螺栓(3)；核心部件由耗能段(1‑1)、自复位段(1‑2)、连接套管(1‑3)和夹持段(1‑4)构成。约束构件(2)的内径大于连接套管(1‑3)的外径，使两者间存在微间隙。在大中震下，由耗能段中间等截面部分(1‑1‑1)产生塑性变形来耗能，其竹节部分(1‑1‑3)保持弹性并限制侧向位移。自复位段(1‑2)可实现震后自复位功能，约束部件(2)可防止核心部件发生低阶屈曲破坏，耗能段与自复位段间通过螺栓连接，可实现震后更换目的。耗能段与自复位段截面及长度尺寸可多样选择。实现了消能减震、震后自复位、震后可更换和灵活组合的功能。
