Swing column-hybrid limb-connected wall structure capable of restoring after being damaged in earthquake and assembly method

Abstract

The invention discloses a swing column-hybrid limb-connected wall structure capable of restoring after being damaged in an earthquake and an assembly method. According to the swing column-hybrid limb-connected wall structure capable of restoring after being damaged in the earthquake and the assembly method, a reinforced concrete wall only generates a bending moment and shear force, axial force generated at the bottoms of wall limbs under the coupling effect is avoided, the energy dissipation requirement for a reinforcing region at the bottom of a shear wall is effectively lowered, damage to the wall limbs can be controlled more easily, the original axial force of the wall limbs is transferred to swing columns on the two sides, brittle shear damage to the wall limbs of the reinforced concrete wall under tension can be effectively avoided as long as the stability of the swing columns can be guaranteed under stress, and force transmission is simple and reliable. According to the swing column-hybrid limb-connected wall structure used as a first defense line for earthquake fortification, a steel coupling beam is good in ductility and high in energy dissipation capacity; a joint connection manner beneficial to replacement is adopted, so that disassembly is easy, and operation is simple; all fixing parts are of a detachable structure and can be re-spliced and re-connected after the energy-dissipation coupling beam is replaced, so that construction and post-earthquake consolidation are made very convenient.

Description

technical field [0001] The invention belongs to the field of structural engineering and structure anti-seismic, in particular to a swing column-mixed limb wall structure and an assembly method with recoverable earthquake damage. Background technique [0002] In the composite wall system, the steel coupling beam has sufficient ductility and plastic deformation capacity, and can provide a fuller hysteretic curve. Under the expected earthquake, the composite wall is a ductile failure form, which solves the problem of small span-to-height ratio coupling beams. The problem of insufficient ductility. However, due to the uncertainty and complexity of the earthquake action, the structure may suffer an earthquake action greater than the fortification intensity. When the earthquake action exceeds expectations, the coupling beam is the first line of defense of the combined wall structure, and damage is inevitable. And due to the influence of coupling, the bottom of the wall pier often...
