Slotted energy-consuming steel pipe shear wall with hybrid dampers

Abstract

The invention relates to the technical field of building structures, and discloses a slotted energy-consuming steel pipe shear wall with hybrid dampers. The slotted energy-consuming steel pipe shear wall comprises steel plate concrete, steel pipe concrete and the hybrid dampers, wherein the steel plate concrete is fixed to the outer side of the steel pipe concrete to form a section of wall limb; each hybrid damper comprises an E-shaped steel plate, a pi-shaped steel plate and a soft steel damping piece; at least one part of each pi-shaped steel plate is inserted into the corresponding E-shaped steel plate, so that a cross part is formed between each E-shaped steel plate and the corresponding pi-shaped steel plate; each soft steel damping piece penetrates through the corresponding cross part and is connected with the cross part; the two ends of each soft steel damping piece are fixedly connected with the corresponding E-shaped steel plate; the outer side walls of each E-shaped steel plate and the corresponding pi-shaped steel plate are fixedly connected with the corresponding steel plate concrete, so that a section of wall limb is connected into the shear wall; and a plurality of sets of hybrid dampers are arranged between every two adjacent sections of wall limbs. The slotted energy-consuming steel pipe shear wall has the beneficial effects that the hybrid dampers can be directly welded to steel plates, the steel plates do not need to be pre-buried, anchoring steel bars do not need to be arranged, and the joint construction difficulty is lowered.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a slotted energy-dissipating steel pipe shear wall with a hybrid damper. Background technique [0002] In recent years, high-rise and super high-rise buildings have emerged in an endless stream. In high-rise buildings, shear walls are mainly used as lateral members to resist the horizontal action of earthquakes and strong winds. However, due to the functional requirements of the building, in some structural layers with small heights such as transfer floors and staggered floors, low walls with small heights and poor ductility will be formed. Under the action of earthquakes, the failure mode of such low walls is mainly It is a shear failure under low shear-span ratio, which belongs to brittle failure and is not conducive to earthquake resistance. [0003] In this context, a slotted energy-dissipating shear wall came into being. [0004] Slotted energy-dissipating she...

AI Technical Summary

Problems solved by technology

Most of the existing slotted energy-dissipating shear walls require on-site pouring, steel bar binding, and the connection with the wall requires pre-embedded many steel plates and anchoring steel bars, etc., which has problems such as cumbersome construction and difficult node connection.
