Abstract

The invention discloses a viscosity energy consumption self-reset shear wall structure with a replaceable bottom. The viscosity energy consumption self-reset shear wall structure with the replaceable bottom comprises at least one structural unit. The structural unit comprises ordinary prefabricated wall sections, a spiral stirrup densification prefabricated wall section, a replaceable wall section arranged on the lower side of the spiral stirrup densification prefabricated wall section, viscous dampers arranged on the two sides of the replaceable wall section, and unbonded prestressed ribs arranged inside a wall body. The spiral stirrup densification prefabricated wall section comprises interior spiral stirrups, embedded plates and vertical connecting plates, wherein the embedded plates are embedded into the interior spiral stirrups, and the vertical connecting plates are connected with the replaceable wall section at the bottom. The replaceable wall section comprises two slotted spiral stirrup densification wall blocks and horizontal connecting plates, wherein the two wall blocks are connected through the horizontal connecting plates. Each viscous damper comprises an upper side support and a lower side support. According to the viscosity energy consumption self-reset shear wall structure with the replaceable bottom, plastic deformation of a prefabricated concrete shear wall can be effectively eliminated, a self-reset shear wall replacement method is simplified, and the cost and the difficulty of replacement conducted after engineering structure earthquakes are substantially reduced.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a viscous energy-consuming self-resetting shear wall structure with a replaceable non-bonded bottom for reducing earthquake disasters of engineering structures. Background technique [0002] Earthquakes bring extremely serious disasters to human beings. The traditional seismic design adopts the ductility design method, that is, under the action of an earthquake, through the early yield and failure of some structural components, but the overall function will not be lost, relying on the plastic deformation of the components to dissipate most of the seismic energy, so as to achieve The purpose of ensuring the safety of the main structure. [0003] Self-resetting concrete shear walls, as a typical energy-dissipating shock-absorbing technology, have been widely used in recent years because of their advantages such as large lateral stiffness, small residual deformation, good shock-absor...
