基于需求刚度的高层双塔连体结构消能减震设计
首发时间:2017-06-07
摘要:以某一钢筋混凝土框架-剪力墙双塔连体结构为工程背景,对双塔连体结构消能减震设计方法进行研究。采用屈曲约束支撑进行消能减震设计,提出了基于需求刚度的参数设计方案。研究结果表明,消能减震结构在多遇和罕遇地震下,结构位移均满足规范要求。屈曲约束支撑耗散了大量地震能量,有效保护了主体结构,减少结构损伤。

Vibration energy dissipation design of a connected double-tower structure based on demand stiffness
Abstract:In this paper, the energy dissipation design method of a double-tower-connected structure was studied. Vibration energy dissipation design was carried out on a reinforced concrete frame-shear wall double-tower-connected structure and a parameter design method based on demand stiffness of the structure was proposed.The results show that the structure story drift meets the specification requirement in the case of frequent and rare earthquake.Buckling constraint support dissipates a large amount of seismic energy, thereby effectively protecting the main structure and reducing structural damage.
Keywords: structuralengineering energydissipation BRB parameter design method double-tower-connected structures
