Structural Characteristic Study On Mega-frame Structure With A Large Bay

Modern high-rise structures have emerged many new forms,mega-frame structure is a typical form. Mega-frame structure has two significant force characteristics, giant beams and giant columns and into the main frame as a major force system, sub-frame beams and sub-frame columns composed of the sub-frame force for the secondary system. Mega-frame structure, power transmission due to its clear, easy-to-building function deployment, saving materials, easy-to-to play a variety of mechanical properties of building materials, etc., has been developed rapidly. With a large bay of the mega-frame structure as a special kind of giant structure, mechanical behavior has a huge framework and rules of the same features, but also has its own characteristics. The article first describes the characteristics of high-rise building, classification, development and vertical structure, system, and so on, explained the definition of mega-frame structure, characteristics, classification, and so the development of the status quo. Then the article Comparative analysis of the two three-layer main frame, on each floor within the main frame, including 6-level framework of the mega-frame structure, mechanical properties of some. One of the rule of mega-frame structure; the other in one big layer of the framework of capitals to remove the fifth floor with the main frame beam connected to the sub-frame columns, forming a large bay with a mega-frame structure. By comparing the analysis of the vertical loads of the bending moment diagram and shaft trying, in the horizontal loads and lateral bending moment diagram under the curves, obtained a number of mega-frame structure with a large bay in the static loads is different from Rules of mega-frame structure features. The article also compared and analyzed with a large bay mega-frame structure under load in a hierarchical order of the construction and simulation, simulation framework of alternating primary and secondary construction, simulation, after the first full-time framework of the three kinds of main frame construction process simulation in case of bending moment diagram shaft trying to explore the construction process of the mega-frame structure with a large bay of the internal forces and deformation effects. End, the article briefly reviewed the development history of earthquake-resistant high-rise building, and a comparative analysis of two kinds of mega-frame structure from the vibration cycle and mode shapes to explore the large hall of structural seismic performance.
