| 摘 要： | 针对地震中震损严重的含薄弱层结构,计算分析了薄弱层对结构抗震性能的影响及其变化规律.基于"补偿刚度"概念,根据阻尼器和附加体系的力学特征,提出了控制薄弱层层间位移的阻尼支撑简化设计方法.通过时程分析验证,该简化设计方法能精准控制薄弱层层间位移到目标值,具有良好的经济性和实用性.

| Abstract: | The structure with weak story will be seriously damaged in earthquake,calculation and analysis of the weak story on the seismic performance and its variation of the structure are progressed.Based on the concept of Compensation Stiffness,according to the mechanical behavior of dampers and added component of the system,the simplified design methods are proposed to control the story drift of the structure with weak story by damped bracings.The time-history analysis shows that the simplified design method can p... |
