摘要

针对框架—核心筒并设置加强层结构的特点,提出了在加强层伸臂中设置耗能构件,并对设置耗能构件和不设耗能构件两种伸臂形式进行静力弹塑性分析,主要对设置加强层结构的静力弹塑性分析中模型的建立、水平加载方式的影响、设置加强层结构塑性铰出现的次序和位置、结构侧移进行了分析。结果表明,设耗能构件可以保证结构在罕遇地震作用下,加强层伸臂首先达到屈服,即能满足"强筒体弱伸臂"的抗震设计要求。
We discuss about the characteristics of frame-core wall structures as well as strengthened story and advance setting energy dissipation member in strengthened stories in detail.The static push-over analysis is conducted for 2 cantilever-type structures with energy dissipation member and without energy dissipation member.The research is mainly about model establishment,effects of different horizontal loading methods,the appearance sequence and position of plastic hinge in the strengthened stories,lateral displacement of the frame-core wall structure in static push-over analysis.The results indicate that strengthened stories with energy dissipation member cantilever yield first and it can guarantee the safety of structure under rare earthquake,which meet the requirements of seismic design.
