【摘要】：随着我国经济持续快速发展,城市化的进度也不断加快。大量人潮涌入城市,为城市的建设、发展带来了源源不断的动力的同时也为城市的发展带来了挑战。为了能够充分利用有限的城市用地,为人们提供充足的居住、办公以及休闲娱乐场所,高层、超高层建筑变成了不二之选。超高层建筑虽然在我国已经有三十年的发展历程,并且我国的超高层建筑拥有数量已经在世界范围内名列前茅,但是我国目前只对高层建筑编著了设计规范,而对那些超高层建筑并未编著相应的设计规范。因此每一座超高层建筑都需要针对其本身的特性进行超限分析,并对结构的安全性、抗震性、可靠性等性能进行评估。本文主要叙述大连一超高层建筑的设计与超限分析过程。本工程为大连市某地一实际工程。总建筑面积63500m2,地下部分三层地下室,地上部分：裙房四层总高17.5m；塔楼三十三层,结构总高136m。结构整体为框架剪力墙结构,塔楼及下部延伸至基础的框架柱以及小部分框架梁采用型钢混凝土结构,其余大部分框架梁以及所有剪力墙和楼板均采用钢筋混凝土结构。结构塔楼采用“新月”形平面布局,结合其建筑功能区的划分,结构的平面布置不完全对称。综合工程所有设计信息,结构主体在高度、平面规则性、以及高宽比等方面均超过了现行《高规》的要求。因此本工程在设计阶段除了进行常规设计以外还应进行超限分析。对于超高层建筑来说,超限分析主要工作就是对结构进行抗震性能分析。本文采用Satwe和Etabs两种结构设计、计算软件对结构分别进行多遇地震作用下弹性性能分析和罕遇地震作用下弹塑性性能分析。将计算所得主要的数据与图像截取收录文中,并进行对比分析。最后按照两种计算软件的计算结果对结构进行包络设计。
[Abstract]:With China's sustained and rapid economic development, city of progress is accelerating. A large number of people into the city, for the city's construction, development has brought Everfount power and challenges for the development of the city. In order to make full use of the city land, provide adequate housing for people, office and entertainment places, high-rise, high-rise building has become the best choice. Although the high-rise building in our country has developed for thirty years, and China has a number of high-rise building has been among the best in the world, but China is only for high-rise building, design specifications, and for those who did not compile the relevant design of high-rise building specification. So every super high-rise buildings need to be overrun according to the analysis of its own characteristics, and the safety of the structure, earthquake resistance, reliable performance. For evaluation. This paper mainly describes the design and analysis of a high-rise building in Dalian overrun process. This project is a practical project in Dalian city. The total construction area of 63500m2, the underground part three basement, ground part of annex four: 17.5m high tower; the thirty-three layer, the whole structure of 136m. high structure for frame shear wall the structure, the frame column and the lower tower extends to the base and a small part of the frame beam with steel reinforced concrete structure, most of the rest of the frame beam and all shear wall and slab adopts reinforced concrete structure. The structure of the tower of "new moon" shaped layout, combined with the division of the functional areas of the building, the layout of the structure is not completely symmetrical. All the comprehensive engineering design information, the main structure in height, rule of plane, and the ratio of height to width were more than the current "high regulation > requirements. This project in the design stage except Beyond the conventional design should also be overrun. Analysis for super high-rise buildings, the main work is to limit analysis of structure seismic performance analysis. This paper uses Satwe and Etabs two kinds of structural design, calculation software of structure were under frequent earthquake and elastic analysis under the rare earthquake elastic-plastic performance analysis. The calculated main data and image capture included in this paper were compared and analyzed. Finally, the structural design of the envelope is calculated in accordance with the two calculation results of the software.
