Post-earthquake function recoverable coupling beam with bending shear sub-control energy consumption mechanism

Abstract

The invention discloses a post-earthquake function recoverable coupling beam with a bending shear sub-control energy consumption mechanism. The post-earthquake function recoverable coupling beam comprises a first elastic coupling beam, a second elastic coupling beam, a connecting bolt and an anchoring part, wherein one end of the first elastic coupling beam and one end of the second elastic coupling beam are connected with an inserting convex block through a connecting inserting groove in an inserting mode and are connected through the connecting bolt, the contact surface of the connecting inserting groove and the inserting convex block is a friction surface, the other end of the first elastic coupling beam and the other end of the second elastic coupling beam are anchored on a wall limb of a shear wall through a shape memory alloy lengthened screw rod and the anchoring part respectively, an n-shaped anti-shearing inserting key is arranged on the wall limb of the shear wall, and the shapes of the other end surface of the first elastic coupling beam and the other end surface of the second elastic coupling beam are n-shaped inserting surfaces matched with the n-shaped anti-shearing inserting key. During an earthquake, the first elastic coupling beam and the second elastic coupling beam shear up and down and move in a staggered mode to drive the friction surface to consume energy, the end parts of the coupling beams rotate with the wall limb, the shape memory alloy lengthened screw rod is driven to generate plastic deformation to participate in energy consumption, and the use function can be quickly recovered after the earthquake.

Description

technical field [0001] The invention relates to the technical field of structure damping, and more specifically relates to a post-earthquake functionally recoverable coupling beam with a bending-shear separate control energy consumption mechanism. Background technique [0002] Shear wall structures are widely used in high-rise buildings due to their good seismic performance. According to the requirements of function and ductility, holes are often opened in the middle of the shear walls to form connected shear walls. The actual earthquake damage shows that the damage of the building is often concentrated on the coupling beam of the shear wall. When the coupling beam is completely destroyed, the damage of the building further extends to the pier of the shear wall. However, it is relatively difficult to repair the traditionally constructed coupling beams and shear wall pier, and the repair costs are high, which is not conducive to restoring the building's use after the earthqua...
