Problems solved by technology

The disadvantage of the replaceable coupling beam is that it can only satisfy the effect of the additional damping ratio when the coupling beam yields under frequent earthquakes. Or under rare earthquakes, the energy consumption effect cannot be further exerted

Abstract

The invention provides a double-step yield energy-consumption connecting beam. The double-step yield energy-consumption connecting beam comprises a web, a flange, a stiffening plate, a connecting plate and a reserved part installed on a shear wall. The two ends of the web are both fixed to the connecting plate, the connecting plate is connected with the reserved part through detachable high-strength bolts, the web sequentially comprises a first web section, a second web section and a third web section, and the first web section, the second web section and the third web section are sequentiallyand fixedly connected. According to the double-step yield energy-consumption connecting beam, under a frequent earthquake, the function that consumed energy provides an additional damping ratio can be developed, the coupling effect of the connecting beam can further be developed, under the design earthquake and the rare occurrence earthquake, a larger energy consumption effect can be developed through the good strain strengthening capability of the stainless steel web sections and yield of common metal web sections, replacement can further be achieved as well in the post-earthquake repairingprocess, and the rapid repairing capability is improved after a strong earthquake occurs on a building.

Description

technical field [0001] The invention relates to an energy-dissipating component of a building structure, in particular to a double-stage yield energy-dissipating connecting beam, which is widely applicable to energy-dissipating and shock-absorbing of high-rise and super-high-rise shear walls. Background technique [0002] Traditional coupling beams generally use reinforced concrete coupling beams, but due to construction requirements, reinforced concrete coupling beams are often designed with relatively small span heights, which can easily cause shear failure of reinforced concrete coupling beams, affect the ductility and energy dissipation capacity of coupling beams, and cause excessive Early damage makes the coupling beam unable to play the role of the first line of defense against earthquakes according to the pre-design goal. Improving the reinforcement method and setting horizontal joints in reinforced concrete coupling beams is not conducive to engineering applications ...
