Function-restorable coupled shear wall with replaceable component

Abstract

The invention relates to a function-restorable coupled shear wall with a replaceable component. The function-restorable coupled shear wall comprises a shear wall body, a replaceable beam, a replaceable wall foot component and a foundation. The replaceable beam and the replaceable wall foot component are reasonably matched, the replaceable component and a non-replaceable part cooperatively work, and the coupled shear wall with multiple anti-seismic defense lines is formed and has higher function recovery capacity after an earthquake. A coupling beam damper is composed of a viscoelastic damper and a metal damper, and the functions of resisting wind and earthquakes are achieved. The replaceable wall foot component is composed of an upper connecting end plate, a lower connecting end plate, a soft steel inner core and steel pipe concrete. Under the action of tension, the soft steel inner core is pulled to stretch, and the concrete does not bear force. Under the action of pressure, the softsteel inner core and the concrete in a steel pipe bear pressure together, the steel pipe does not bear force, and only a restraint function is achieved on the concrete. Damage of the coupled shear wall is focused on the coupling beam damper and the replaceable wall foot component, replacement is convenient, a non-replaceable section in the shear wall is kept good, and the structure function can berestored.

Description

technical field [0001] The invention belongs to the field of recoverable functional structure systems, and in particular relates to a recoverable function coupled shear wall structure with replaceable parts. Background technique [0002] Reinforced concrete shear walls are currently one of the most widely used lateral force-resisting components in high-rise and super high-rise buildings. Shear walls often bear most of the seismic shear force of the entire structure. very important. However, in the Wenchuan earthquake and the Chilean earthquake, it was found that many coupling beams and wall piers were seriously damaged, the coupling beams were brittle, forming X-shaped cross cracks, the concrete at the foot of the shear wall was severely crushed, and the longitudinal steel bars were buckled. The damage of connecting beams and wall piers after the earthquake is difficult to repair, resulting in huge economic losses. A combined shear wall with multiple anti-seismic defense l...

Problems solved by technology

Replaceable coupling beam dampers or replaceable wall foot parts also have problems such as stiffness or bearing capacity that do not match the shear wall

[0004] Chinese patent CN207032555U discloses a building anti-seismic structure based on a recoverable function combined shear wall, which includes a recoverable function combined shear wall with replaceable coupling beams and steel tube concrete bearings, and through connecting pieces and combined limbs For the floor slab connected with the shear wall, replaceable components are installed in the middle of the replaceable connecting beam. Tension-compression and weak-shear-torsion connectors are connected to the joint shear wall, but this structure has the defect that the concrete-filled steel tube support cannot be replaced after it is damaged
