【摘要】：随着经济的快速发展,我国的建筑行业发展迅速,特别是超高层建筑适应潮流而得以高速发展。超高层建筑对其所在的城市的发展具有重要的影响,以它绝对的规模和建筑数量,就对城市街区的集中化、对街上的行人以及街景本身都具有明显的重要性。无论是独立的超高层建筑,还是融入在城市环境里的建筑,建筑物的体量越大,影响也就越大,同时一栋超高层建筑从前期调研到设计再到施工建成,将花费巨大的人力和财力,超高层建筑一旦出现问题,将导致无法挽回的经济损失和巨大的人员伤亡。因此,对超高层建筑进行详细的分析和研究,显得尤为必要。对于超高层建筑而言,随着建筑物层数的增大,各种结构问题更加明显,风荷载和地震作用将在结构上产生更大的反应,而结构在荷载作用下的内力计算也会更加复杂。超高层建筑的设计理论、设计方法、施工技术等在新的形势下需要有更好的发展。超高层建筑需要不断寻求理论创新和思想创新。本文对某典型的超高层建筑结构,采用理论分析和数值模拟相结合的方法,进行了结构整体受力性能的分析。钢板剪力墙由于其独特的结构特点,具有优越的抗震性能,被越来越多的运用于超高层建筑。本文重点对工程中运用的钢板剪力墙进行了分析,提出了钢板剪力墙结构的建模方法,从而实现了对含有钢板剪力墙的超高层建筑的数值分析。对于本文,我是在现有计算理论的基础上,结合有限元分析软件,建立超高层结构的计算模型进行数值模拟分析,得出准确的计算结果,最终完成对结构力学性能的计算。通过相应荷载的计算,将计算荷载施加到结构模型上,通过软件自动进行计算,最终得出结构水平位移、竖向位移和结构应力的计算结果,及其它需要的计算结果。在模拟计算过程中,我提出了不同的结构建模方法,对钢板剪力墙建模的思路进行了理论探讨,通过对不同的建模方法的探讨分析,认为两种钢板剪力墙的建模方法都具有实际运用的价值。
[Abstract]:With the rapid development of economy, the construction industry of our country has developed rapidly, especially the super high-rise building has been developed rapidly in accordance with the trend of development. Super high-rise building has an important influence on the development of the city in which it is located. With its absolute scale and the number of buildings, it is of great importance to the centralization of the city block, to the pedestrian on the street and to the street view itself. Whether it is an independent super-tall building or a building that is integrated into an urban environment, the larger the volume of the building, the greater the impact. At the same time, a super-high-rise building will be built from early research to design to construction. It will cost huge human and financial resources. Once problems occur in super high-rise buildings, it will lead to irreparable economic losses and huge casualties. Therefore, it is particularly necessary to analyze and study the super-high-rise buildings in detail. For super-tall buildings, with the increase of the building floor, the structural problems become more obvious, the wind load and earthquake action will produce a greater response on the structure, and the calculation of the internal force of the structure under the load will be more complex. The design theory, design method and construction technology of super-high-rise building need better development in the new situation. The super-high-rise building needs to seek the theory innovation and the thought innovation unceasingly. In this paper, a typical super-tall building structure is analyzed by the combination of theoretical analysis and numerical simulation. Because of its unique structural characteristics, steel plate shear wall has excellent seismic performance, and is used more and more in super high-rise buildings. This paper focuses on the analysis of steel plate shear wall used in engineering, and puts forward the modeling method of steel plate shear wall structure, thus realizing the numerical analysis of super high-rise building with steel plate shear wall. In this paper, on the basis of the existing calculation theory and combined with the finite element analysis software, I set up the calculation model of super tall structure to carry on the numerical simulation analysis, get the accurate calculation result, and finally finish the calculation of the structural mechanical performance. Through the calculation of the corresponding load, the calculated load is applied to the structural model, and the calculation results of the horizontal displacement, vertical displacement and structural stress of the structure are obtained by the software automatically, as well as other necessary calculation results. In the process of simulation and calculation, I put forward different structural modeling methods, discussed the train of thought of steel plate shear wall modeling, and analyzed different modeling methods. It is considered that the two modeling methods of steel plate shear wall have practical application value.
