| Several high-rise building through the bottom one-floor or various-floor base of large site connected to the overall structure, called the "multi-tower structure", also called "big base and multi-tower structure". Along with the rapid development of the science, technology, the economy, and the increasing growth of population, the land of the city becomes more and more treasure, the high-rise and small high residential building of large basement gradually become a trend in the residential area design.There are green area and road between high-rise buildings. There is the single basement or multi-layer basement under the ground, the whole basement use regardless of structural joint approach, as a whole with the high-rise buildings on the ground, which makes the analysis and calculation of the structure becoming more complicated. We makes use of series software of the PKPM to build model, revisit the models, with an example of the project of Anhui Langxi Dongcheng internation, and to analyze and calculate the seismic resistance and stability of the structure, and finally finish the structure design of the projectAnhui LangXi Dongcheng internation is a high-level residential area, including one layer of underground garage,5high-rise residences and3commercial buildings of two floors on the ground. Five high-rise residences are shear wall structure, and the business part is the frame structure. Due to the structure size of the business part being very small, relatively speaking, stiffness is also small, so we can take out it to analyze and calculate separately. In fact, the project is big base and five-tower structure.Through participating in analysis and calculation of this engineering structure, I have a deeper understanding to the complicated structure such as the big base and multi-tower structure, and win a lot of practical design ideas and solutions. At the same time, I integrate theory with practice and put it into the structure design, Finally, improving myself more and more. |
