【摘要】 随着建筑技术的发展，建筑形势日趋多样化。连体建筑由于其宏伟的气势、现代化的气息而被建筑师们所喜爱。连体建筑是指在两个或多个建筑由设置在一定高度处的连体相连而组成的建筑物。由于连体的存在，使得原来彼此独立的各单体结构分别变成了一个系统中的一部分，其静力特性、受力机理等与单体结构相比均发生了变化，值得进一步研究。连体结构的研究对该类结构形式今后的发展具有重要的理论意义。 首先，针对“东方之门”的工程特点对其进行了弹性阶段的静力分析。考虑连体的位置、层数、连体的刚度等因素进行了整体参数分析。 其次，对“东方之门”进行了静力弹塑性pushover分析。首先介绍了pushover方法的基本原理和应用范围，详细叙述了能力谱方法的基本理论及实现手段。对于本工程，本文进行了两个方向的静力弹塑性分析，得到结构在多遇及罕遇地震下的性能点、结构的倒塌机制。在此基础上，结合我国规范，给出了本结构的抗震性能水准。 最后，本文在上述分析的基础上得出了一系列针对本工程的结论及一些针对门式高层结构具有一定普遍意义的结论。这些结论对本工程的设计具有指导意义，对类似结构的分析具有一定的参考价值。更多还原

【Abstract】 With the development of technology, the types of architecture become more and more diversified. The architects like to design the connected architectures because of their magnificent figuration and modern feeling. When one or more corridors were setting between two or more buildings at some height, the all system was called the connected architecture. Because of the joining of the corridor, the two monomer structures become one part of the whole structure, so compared with the monomer structures, their static property, stress mechanism varied and they are worth making further studies. It is important to do some research for the development of the connected structures.Firstly, combining the characteristics of "East Gate", the static analysis of the project in elastic stage is performed. In this paper, considering the position of the corridor, the stories of the corridor, the stiffness of the corridor and so on, the parameter analyses are done.Secondly, the static elastoplastic pushover analysis of "East Gate" is performed. First of all, the basic principle and applying range of pushover is introduced, and a detailed description of the capacity spectra theory and realization is presented. For this structure, static elastoplastic pushover analysis in two-direction is carried out. Finally, the structural behavior and the rule of collapse under serviceability and maximal earthquake are concluded. Based on the analysis and combining with national code, the seismic performance level of "East Gate" is presented.Finally, on the basis of the above analysis, some conclusions for "East Gate" are put forward. These conclusions are directly meaningful for this project and could be used as a reference for similar portal super high-rise buildings.更多还原
