Analysis Of Tall Buildings With The Beam Transfer Layer Performance

In recent decades, the construction of tall buildings around the world increasing height, the span increases, the structure toward the system of modern high-rise building complex, feature-rich comprehensive direction to meet the industrial development and people's increasing material cultural needs, and thus building more and more complex and diverse structure.In the high-rise building structure, to meet the functional requirements of building use, often set in the structure conversion layer. Beam conversion layer due to its power transmission direct, clear, easy calculations have been widely used. Transfer story high-rise building structure set uniform vertical stiffness of the structure after damage, power transmission means has changed dramatically, so it is necessary to analyze the seismic behavior of structures. Therefore, this paper combined with previous studies in the conversion layer, based on the finite element analysis, design software SAP2000 to establish a three-dimensional model, based on conversion layer set height on seismic performance of tall buildings response Spectrum Analysis carried out, including the natural period of structure, floor displacement, story drift angle of impact and the equivalent lateral stiffness ratio on the seismic performance. Paper further analyzes the structure of the earthquake zone transfer beam high-rise building set to change the flexibility of a high Dynamic Response, for its dynamic response characteristics, the setting of the conversion layer in the seismic design should pay attention to the problem, summarizes the appropriate and effective measures and solutions, and propose a framework of earthquake zone wall structure of the design point. After analysis the following conclusions: As the height increases conversion layer set, building the bottom of the box support layers increased, a corresponding reduction in the upper part of wall layers, resulting in lateral stiffness decreases, the structure of the natural cycle of increases; the first few vibration modes seismic effect the level of control, higher modes of the structure With the set of transition layer will gradually increase the height increases; conversion layer on layer to set the displacement curve of height had a significant effect, when the conversion layer location gradually increased, the structural model of the story drift curves of the changes tend to significantly affect, the structure of the top displacement increases; in the conversion layer location and structure of the lateral stiffness of a mutation causing the displacement of parts of the layer near the mutation; and with the conversion layer elevated position, this mutation increased gradually; upper and lower compared to the equivalent lateral stiffness ratio, lower than the equivalent shear rigidity, a more accurate measure of the structural response to earthquake in the conversion layer of upper and lower level of mutation ; conversion layer structure of the space position of integrity, in the same position under the higher conversion level, the conversion layer, the lower lateral stiffness than the equivalent structure, the greater the seismic performance of the worse, the worse the overall space.This paper studied the wall structure of reinforced concrete frame under earthquake response performance, the impact of the seismic response calculation of the main factors analyzed, the species of Results Configuration system has a better understanding of the similar high-level and high-rise building is provided in the seismic design of reference.
