摘要(Abstract):

以一高空柔性连接的钢结构连廊为例,阐述了该类结构抗震性能设计的关键技术。首先通过比较分析建立考虑连廊与主体结构相互作用的连廊计算模型;通过提取连廊支座处的地震加速度和支座沉降,得到连廊抗震分析的外部作用;然后基于准确的计算模型和外部作用,对连廊进行分析计算,评估其抗震性能,并得到满足抗震性能目标的支座反力和安全滑动距离;最后对连廊支撑体系的抗震性能进行评估。
A steel structure connecting corridor with flexible connection was taken as example to illustrate the key technique of seismic performance design of this kind of structure. Firstly,through the comparative analysis,the calculation model of connecting corridor was established considering the interaction between corridor and the main structure. External action for connecting corridor seismic analysis was obtained by extracting the earthquake acceleration and support settlement at the support of the connecting corridor. Then based on accurate calculation model and the external action,the connecting corridor was analyzed and calculated to evaluate its seismic performance and obtain the support force and safety sliding distance which meet the seismic design objectives. Finally the seismic performance of the support system of the connecting corridor was evaluated.
