摘要
钢筋混凝土框架—摩擦剪力墙是一种良好的减震结构。本文应用现代控制理论提出了小震时控制其所有摩擦剪力墙不滑动,框架和墙体处于弹性阶段,大震时控制其摩擦剪力墙滑动耗能(墙体仍为弹性),但框架变形不超过减震要求(如开裂,轻微破坏等)的减震控制设计方法。计算实例表明,由此所得的框架-摩擦剪力墙结构,其减震效果完全符合设计减震要求。
This paper presents a control design method for shock absorption of R.C. frame-friction shear wall structures. In which the frictioe shear walls do not slied and the structures are within the range of elasticity under small earthquake tremor, and the friction shear walls slide to dissipate energy and deformation of the satisfies design requiremint with shock absorption under large earthquake tremor condition.
