发布时间：2018-12-14 10:15
【摘要】：近些年来，我国经济快速发展，许多城市兴建了大量的超高层建筑，高度多在二百米以上。传统的钢筋混凝土结构逐渐暴露出其在超高层建筑中的缺点，如构件截面尺寸过大，结构自重较大等等。为解决这些问题，钢结构及钢-混凝土混合结构逐渐在超高层建筑中得到应用，尤其以钢-混凝土混合结构得到了快速的发展与应用。 本文以天津远洋大厦二期项目为工程实例，对钢-混凝土混合结构在超高层建筑中的应用进行了较为深入的分析与研究。文中对该工程的抗震设防标准和抗震性能目标做出了详细的分析，对结构体系选型和结构布置进行了详细的介绍，采用建筑结构空间有限元分析软件进行了多遇地震及设防地震作用下的结构分析，，并且采用EPDA动力弹塑性时程分析软件对结构进行了罕遇地震作用下的弹塑性验算。文中对该工程的抗风设计也做出了详细的阐述。
[Abstract]:In recent years, China's economy has developed rapidly, many cities have built a large number of super-tall buildings, most of which are over 200 meters high. The traditional reinforced concrete structure gradually exposes its shortcomings in the super high-rise building, such as the section size of the members is too large, the weight of the structure is large, and so on. In order to solve these problems, steel structures and steel-concrete composite structures have been gradually applied in super-tall buildings, especially steel-concrete composite structures have been rapidly developed and applied. Taking the second phase project of Tianjin Ocean Tower as an example, the application of steel-concrete hybrid structure in super high-rise building is analyzed and studied in this paper. In this paper, the seismic fortification standard and seismic performance target of the project are analyzed in detail, and the selection and arrangement of structure system are introduced in detail. The spatial finite element analysis software of building structure is used to analyze the structure under the action of frequent earthquake and seismic fortification, and the EPDA dynamic elastoplastic time-history analysis software is used to carry out the elastic-plastic checking calculation of the structure under rare earthquake. The wind resistance design of the project is also described in detail.
