The high-strength reinforcing bar comprises the longitudinal bar with the yield strength more than 500MPa such as rebar, steel wire, high-strength steel strand and fiber-reinforced composite (FRP); the high-strength reinforcing bar can be dispersed at the circumference of the edge component or arranged in the edge component in a concentration way. The self-recovery concrete shear wall can improve the antiroll stiffness of the shear wall, postpone the degradation of the antiroll stiffness, lead the structure to have the self-recovery capability and reduce the structural residual deformation after earthquake.
Description
Invention field
The concrete shear force wall that can reset certainly of configuration high-strength reinforcing bar belongs to the reinforced concrete shear wall technical field.
Background technology
Current, various countries' structural aseismatic design adopts the criterion of setting up defences of " not bad, the middle shake of little shake can be repaiied, no collapsing with strong earthquake " more, shake and big shake structure generation nonelastic deformation down in the permission.The building that designs in view of the above and build has guaranteed people's life security, along with The development in society and economy, is that the target of providing fortification against earthquakes can not satisfy and provides fortification against earthquakes now and the demand of social life with life security.
Early 1990s, American scholar takes the lead in proposing the Aseismic Design Theory based on displacement, and its core concept is control structure displacement on the whole and relative storey displacement level.This is the Aseismic Design Theory of target with control maximum distortion (structure total deformation or stratified deformation) mainly, when emphasizing structure ductility, ensureing structural performance, further guarantees structural safety, has constituted the important content based on the performance Aseismic Design Theory.Yet,, pay close attention to the maximum distortion of structure more and ignore shaking the control of back structure permanent set in research based on the existing Seismic Design Method under the performance framework.
Can permanent set be to weigh an important indicator that continue to satisfy instructions for use and recoverability after structure is shaken, the excessive structure of permanent set is often finally removed because can't repair, to the research of structure permanent set and control thereof, also be to have one of important content based on the research of performance Aseismic Design Theory now.
Along with development of modern science and technology, increasing high-strength and high performance material is applied to engineering structures, for the control structure permanent set provides possibility.Wherein, Materials with High Strength can be used for reducing to shake the permanent set of back structure with its higher elastic recovery properties, has been used to attempt building (Self-Centering) new structure that resets certainly that is intended to reduce shake back permanent set.
Summary of the invention
The purpose of this invention is to provide a kind of shear wall member that has from reset function.The concrete shear force wall of preparation high-strength reinforcing bar can reduce under the geological process because the permanent set that the longitudinal reinforcement surrender produces, and improves the functional performance behind the structural earthquake, improves recoverability.Described high-strength reinforcing bar is reinforcing bar, steel wire, high strength steel strand and fibre reinforced composites (FRP) muscle of yield strength more than 500MPa.
The invention is characterized in a part of muscle of the vertical distribution bar of a part of muscle or wall sheet middle part in the vertical muscle of the concrete shear force wall end edge member that can reset certainly of described configuration high-strength reinforcing bar, is high-strength reinforcing bar.
The present invention improves the anti-side rigidity of shear wall by the configuration high-strength reinforcing bar, delays the deterioration of anti-side rigidity, makes structure have runback potential energy power, the permanent set of structure after the minimizing earthquake.

The specific embodiment
The concrete shear force wall that the present invention proposes is on ordinary reinforced concrete shear wall basis, and the vertical muscle of the part of end edge member is replaced to high-strength reinforcing bar; Perhaps vertical muscle of the part of end edge member and the body of wall middle part vertical distribution bar of part are replaced to high-strength reinforcing bar.
High-strength reinforcing bar of the present invention comprises reinforcing bar, steel wire, high strength steel strand and fibre reinforced composites (FRP) muscle of yield strength more than 500MPa.
Can be to bond together between high-strength reinforcing bar of the present invention and the concrete, also can not have bonding.
High-strength reinforcing bar vertical reinforcement of the present invention can dispersed placement around edge member, also can be in the edge member centralized arrangement.
In building course, the concrete shear force wall and the common shear wall construction technology of preparation high-strength reinforcing bar are basic identical.When adopting the bonded prestress reinforcing bar and applying pretension, need be in shear wall reserving hole channel.
The concrete shear force wall of preparation high-strength reinforcing bar should guarantee the member shear strength greater than flexural strength, prevents that shear failure from taking place prior to bending failure.
