| With the advances of technology and economic development, the growing popularity of high-rise structures. It is more and more types of material and structure began to diversify. Force features a variety of structures to resist seismic horizontal load on capacity, inter-layer lateral acceleration, speed and performance isolation,so this is a significant difference. With the continuous progress of human, social and environmental crisis pushed the limits of human technology to explore. Small footprint, superior mechanical properties of high-rise, high-rise building construction designers will increasingly become a favored target. Good built environment and the potential value of different forms of artistic and Structure, the senior has been widely applied in real life.Not only the rise or high-rise buildings are in need of social development currently, but also the product of scientific and technological progress. It has been customary to increase the number of high-rise buildings as a measure of the height of one of the important measure of a city’s economic development level and the extent of the application of science and technology. With the deepening of theoretical research and engineering application of continuous practice, has also been a test of the architect’s imagination, in the form of high-rise building structures are also increasingly rich, able to give direct visual experience.Diversified, high-rise structure is an inevitable product of the structure, and it is driven by the emergence of another system, mega-frame architecture. It has two main features: first, it’s integrity, stiffness, as well as unique seismic performance; Second, the giant frame, one can build different structures according to their wishes, the internal components can reasonably be arranged. Mega-frame architecture, has become increasingly recognized by society.Jumbo frame system is to assist the inevitable trend of high-rise buildings, and many of its features are accompanied by high-level requirements and a student representative significance of the new system. It will not only be able to meet the requirements of multi-purpose building, its unique mechanical characteristics one can enhance the integrity of its own. On the other hand the vertical layout of the different structures to meet the functional requirements of the building. And also has a structural seismic performance, power transmission clear, good integrity, construction speed, save material, reduce the project cost, the advantages of a variety of forms and can be a combination of structural materials and many other. Currently, fasting style mega-frame structure has been widely recognized for abdominal giant frame in real terms of the structure, which has superior mechanical performance, while effectively saving materials, reducing the project cost.This article itemized sequence introduces high-rise buildings, giant frame structure, the knowledge vierendeel mega-frame structure, and then use the software to simulate the creation SAP2000 related fasting style mega-frame model. Under the conditions of seismic fortification intensity of 7 degrees, under the category of Class Ⅱ site soil conditions, the input of two natural wave El-centro, Taft and an Lanzhou wave can create modal analysis and time history analysis. Through fasting giant main frame columns and seismic analysis and comparison of the mechanical properties of the main frame of solid abdominal giant columns of different cross-sectional area of research and study fasting column seismic impact on the overall framework of the giant, through structural analysis, we can get: Fasting style mega-frame than the real abdominal rectangular frame structure in terms of better performance seismic force; for fasting style mega-frame structure, a certain proportion of fasting seismic sway smaller. Through a variety of fasting section, study the structure of the earthquake that fasting is smaller, and ensure safe living. From the aspects of cost and save energy, fasting column is better. |
