Hilton Hotel Building Seismic Performance Research For Lanzhou Center

In the late 80 s, with the development of our economy and the improvement of our comprehensive national strength, super high-rise building has been developed rapidly. These buildings can improve the image of the city and they can be taken as landmark of a city, which will play a positive role in promoting the city. City’s architecture are built toward high altitude, especially in large cities with million of people. Therefore, design and construction of super high-rise building are still what people should focus on. However, more and more super high-rise buildings are beyond the scope of rules and regulations of China’s building structure design in many aspects, such as, height and plane layout, and have formed transfinite structure with the features of high height, complicated graphic design and irregular vertical design. But the structure, which is beyond the scope of rules, has negative influence on the anti-seismic performance of the structure. Therefore, it is significant to discuss the anti-seismic performance of the structure.The paper mainly expounds the research status and importance of the following aspects, namely, the general situation of super high-rise building, the judging standard of transfinite structure, Seismic design theory Based on the performance as well as Elastic-plastic analysis method. The thesis take Hilton Hotel, which locate in Lan Zhou, as research object, and mainly introduces its engineering situation, prominent design condition and standard, and make a judgment to the building. According to the related specifications, the author sets seismic performance goals which functions in the following situations, like, severe earthquake, earthquake resistance, the rarely met earthquake. It is found that the Hilton Hotel belongs to B building and hold that target D is goal of the building in the seismic performance.By using SATWE calculation software, the author calculates the anti-seismic performance under the situation of earthquake of the Hilton Hotel buildings, then the time history analysis method is applied to make a complement calculation for seismic performance of structure under the action of minor earthquakes, finally the author make a comprehensive analysis on the anti-seismic performance and structure features of the hotel in more severe earthquake. It is found that the maximum interlayer displacement angle of Hilton Hotel is 1/836 in more severe earthquake. In addition, coupling beam structure as a whole is in elastic state, which meets the requirement that it functions well in severe earthquake.The thesis introduces the static elastoplastic analysis method and the principle of elastic-plastic time history analysis method. By using the finite element calculation program PUSH&EPDA, the author analyzes the action of static elasto-plastic analysis and dynamic elastic-plastic time history analysis to Hilton Hotel towers. Comprehensive study the earthquake response of structure under severe earthquake to judge whether the building exists obvious weak layer and has good seismic performance in Elastoplastic state. And the research found that the maximum interlayer displacement Angle is 1/122, the largest displacement of the vertices of 1.009 m, Structures of plastic deformation and the damage location and order is complied with the design exception, and meet the requirement that the builing will not collapse in big earthquake. Finally, the author makes a comparison between the two kinds of elastic-plastic calculation data, and draws a conclusion on the similarities and disparities of these two kinds of methods. By studying the anti-seismic performance and the analysis methods, it is hoped that the research can provide certain reference to the similar engineering.
