延性折板式钢板剪力墙

DUCTILITY STEEL FOLDED PLATE SHEAR WALL

多高层建筑结构长期存在的问题之一是:框架容易做成延性结构,而抗侧力结构如剪力墙却延性很差。探讨折板式钢板剪力墙,就是对延性抗侧力结构的尝试,其基本思路是利用折板式的几何形状,使钢板先达到材料屈服极限,避免钢板剪力墙出平面的弹性失稳,充分发挥材料的强度和延性。

One of the main problems of high and multiple stories buildings is that the ductility behavior can be realized in frames,but very difficult to make it in shear walls.In the paper,the authors developed a new form to use ductility steel folded plate as shear wall.The geometric form of the folded plate let the steel reaches yielding limit before reaches its elastic buckling limit.The buckling of steel could be avoided.The ductility and load-carrying capacity of steel can be developed fully.The hysteretic property is also good.
