Vertical rib corrugated web steel-concrete combined coupling beam

Abstract

The invention provides a vertical rib corrugated web steel-concrete combined coupling beam which at least comprises a plurality of steel flanges, steel corrugated webs, high-damping concrete, butt weld joints and reinforcing plates, wherein the steel flanges and the steel corrugated webs are assembled in a factory to form a coupling beam steel box which is used as a mold plate into which the high-damping concrete is cast on site. The steel corrugated webs have relatively large out-of plane stiffness, so that out-of plane deformation of a coupling beam outer steel plate can be effectively inhibited; the steel flanges and the steel corrugated webs are connected through the butt weld joints, so that connection strength can be ensured; due to adoption of the high-damping concrete, the couplingbeam has remarkable advantages in bearing capacities, energy consumption and rigidity; due to the structure of vertical rib corrugated webs, completeness of connection nodes of beams and walls can beensured. The coupling beam is applicable to connection of steel-concrete combined shearing walls in a high-rise hybrid structure system, is capable of meeting requirements of overall structures on deformation and energy consumption of coupling beams when being compared with a steel reinforced concrete coupling beam, and in addition is good in construction convenience, and the engineering manufacturing cost can be reduced while the construction progress is accelerated.

Description

technical field [0001] The invention relates to the technical field of super high-rise hybrid structures, belongs to the category of steel-concrete composite structures, and specifically relates to a steel-concrete composite connecting beam, which can match the outer-wrapped steel plate-concrete composite wall in terms of rigidity, bearing capacity and deformation capacity. Improve the mechanical performance of the combined shear wall and reduce the damage of the main structural components under the earthquake. Background technique [0002] In the high-rise composite structure system, the shear wall or the cylinder composed of the shear wall is the main lateral force-resisting member. With the development of society and economy, the function of buildings has been continuously improved, and the height of buildings has been continuously increased, so the performance of shear walls in high-rise structures has been put forward higher requirements. So the steel-concrete composit...

AI Technical Summary

Problems solved by technology

Among the existing coupling beam forms, the bearing capacity and deformation capacity of reinforced concrete coupling beams are low, and it is difficult to match with the wall pier; the structural form of the built-in steel plate-concrete coupling beam is quite different from that of the composite wall pier. It is difficult to realize the connection with the wall; the cost of the steel connecting beam is relatively high
