Energy-consumption shear wall made of composite material

Abstract

The invention discloses an energy-consumption shear wall made of a composite material, which comprises an upper steel plate, a lower steel plate, a middle steel plate, a constraining steel plate, a viscoelastic material, lead cores and bolt holes, wherein prepared holes are formed in the middle steel plate and the constraining steel plate; the viscoelastic material is arranged between the middle steel plate and the constraining steel plate; after the steel plates and the viscoelastic material are vulcanized together, lead is poured into the prepared holes to form the lead cores through curing; the bolt holes are formed in the upper steel plate and the lower steel plate; the upper steel plate and the lower steel plate can be connected with an upper frame beam and a lower frame beam through bolts to form the energy-consumption shear wall. Under vertical load, wind load and small earthquakes, the energy-consumption shear wall only provides rigidity to resist vertical load, lower horizontal load and bending moment; under middle and large earthquakes, the energy-consumption shear wall can consume earthquake energy due to the viscoelastic material and the lead cores; when the viscoelastic material and the lead cores deform greatly, the energy-consumption shear wall can provide not only rigidity but also damping to reduce various earthquake response of the energy-consumption shear wall; the numbers of the viscoelastic material layers and the lead cores can be changed as required. The energy-consumption shear wall is clear in seismic concept design, simple in structure, low in material cost, and convenient to construct and replace.

Description

technical field [0001] The invention relates to a composite material energy-dissipating shear wall, which belongs to the field of anti-seismic structural systems. Background technique [0002] Shear wall, also known as seismic wall, mainly bears the horizontal load caused by earthquake in the building structure, effectively improves the lateral stiffness of the structure, and reduces the lateral movement of the structure under the horizontal load. Under moderate and severe earthquakes, the structure consumes seismic energy through elastic-plastic deformation and damage, which causes large deformation of the structure. In order to achieve a good seismic effect, it is necessary to increase the cross-section and reinforcement of the shear wall, which is economical. poor. That is to say, it is difficult to balance the seismic performance and economic performance of traditional shear walls. At the same time, due to the emergence of complex, irregular, conjoined and super high-r...

Problems solved by technology

However, energy-dissipating and shock-absorbing devices are generally arranged in places where the relative displacement between floors is relatively large through supports. Whether it is in the form of diagonal braces, herringbone braces or interstory columns, it will affect building functions and architectural design.
