竹材双层楼板摩擦减振与顶部TLD联合减振体系的理论推导

Deduction to joint vibration reduction formula to double slab friction damping and the top TLD through bamboo model

结合第五届全国大学生结构设计竞赛赛题对竹材结构模型提出了双层楼板减震与顶层TLD联合减振的方案,并进行了理论推导,得到了双层楼板的分离加速度公式,并得到了相应结构体系在楼板层加速度小于和大于分离加速度情况下的运动微分方程。

According to the examination questions in the Fifth College Structure Design Competition,we put forward a plan of joint vibration reduction to double slab friction damping and the top TLD through bamboo model.By the theoretical deductions,we achieve the formula to double slab separation acceleration,and the kinematics differential equation of responding building system under the circumstances of slab acceleration less or more than the separation acceleration.
