An experimental study of buckling-restrained steel plate shear walls with inclined slots

摘要：

　　This paper presents a novel buckling-restrained steel plate shear wall with inclined slots(simply referred as “slotted SPSW,as shown in Figure 1)that can be one of the most cost-effective devices in seismic-prone regions to improve the structural energy dissipation capability and provide higher resistance and stiffness against lateral forces.The slotted SPSW consists of boundary members and an inner steel plate with inclined slots sandwiched between two external concrete panels.The inclined slots create steel strips in one direction only,but with the restraint provided by the precast concrete panels on both sides,these inclined strips behave like a series of buckling re-strained braces to dissipate the energy through inelastic axial deformation during reversal loading.A half-scale slotted SPSW quasistatic cyclic test was carried out to provide the data about the general behavior of the slotted SPSWs.When a slotted SPSW is properly de-tailed and fabricated,bucking failure of the steel strips can be avoided and the slotted SPSW can sustain a roughly 2.8%lateral drift ratio without a reduction of the shear force and energy dissipation ratio.
