摘　　要：利用模型试验研究了分离式外套框架和结合式外套框架增层结构的抗震性能 ,探讨了在外套框架与原结构之间设置连接件后 ,整个增层结构刚度受到的影响以及动力特性和动力响应的变化 ;验证了一种在保证原结构可靠性的基础上 ,降低整体结构地震响应的方向和方法 ,也为采用外套框架增层结构的未来设计和优化控制提供了一定的依据。本试验研究是在理论分析计算的基础上完成的。In this dissertation, the experimental model was used to study the aseismic properties of separated external frame or combined external frame storey increasing structures. The effects and changes on stiffness, dynamic properties and dynamic response of the storey increasing structure were studied on condition that the special connections between the original structure and external frame were placed. The tendency and method to decrease the seismic response of the total structure on the basis of keeping the reliability of the original structure has been proved. Some experimental evidence for future design and optimizing control of the external frame storey increasing structure is provided. Our experimental study has its theoretical foundation.
