Traditional shear wall is all thinner, so distribution bar all adopted the linearity layout, separately establishes lacing wire between the steel mesh reinforcement of both sides.Because high-rise, super highrise building in recent years emerges in an endless stream, in corresponding building, shear wall thickness is also more and more thicker, and concrete grade is more and more higher, structural seismic performance is required also more and more higher, needs member to possess higher ductility.The precondition that the thickening of shear wall thickness provides distribution bar to adopt other form, and higher ductility demand has proposed to adopt the demand of other distribution bar form.
Main relevant to limit compressive strain and the concrete restraint condition of concrete material through the ductility that experiment showed, shear wall.At present, use strong concrete in shear wall, although the bearing capacity of high-strength concrete is higher, deformability is relatively poor.Shear wall is joined hoop district and only is positioned at shear wall end edge member, only depends on whether strengthen district and antidetonation grade, and irrelevant with the stress of wall, this can cause pressure than the large part constraint not, causes concrete to damage by pressure too early.Retrain good compressive reinforcement and can help the concrete pressure-bearing, reduce the actual depth of compression zone of concrete, just can consider during such as checking computations beam-ends concrete compression district height that pressurized indulges the advantageous effect of muscle.But because the lacing wire of original shear wall reinforcement manner and transverse reinforcement are not enough to the longitudinal reinforcement constraint, the pressurized longitudinal reinforcement will flexing during initial the loading in experimentation, can't play the effect that improves ductility of sheer wall.Further after research, the ductility of sheer wall measure that improves of employing is mainly to add shaped steel or steel plate, increase horizontal distribution muscle reinforcement ratio or adopt high tensile reinforcement, employing segmentation constraint to join the measures such as hoop form, but binding effect is still undesirable.
