Framework - The Mixing Tube Experimental Study On Seismic Analysis

In recent years, large parts of the world frequent occurrence of an earthquake disaster, and now social development, high-rise buildings has become a mainstream, how to effectively improve the seismic performance of high-rise buildings has become a major subject of current research. After people continue to study and experiments, steel - concrete composite structure can be brought into full play the advantages of steel and between concrete has become the current high-rise buildings in particular, more than 100 meters high or even high-rise buildings form the main structure, and its advantages has been in the actual project has been effectively proven. Strip steel - concrete composite beams frame mixing tube is a new structure of strip-Concrete-mixing tube in under cyclic loading hysteretic behavior, ductility, seismic dissipation capacity, failure mechanism, equivalent stiffness of seismic performance, and for guiding the design, promotion framework - mixed tube system, the development of relevant regulations are of great significance. The main contents of this paper are the following:(1) The combination of the existing nodes, hybrid coupled shear wall based on the research, applied mechanics, concrete structures nonlinear theory, the proposed framework - mixing cylinder experimental program, and the proportion of a model for the combination of beams with 1:5 frame - tube were mixed Cyclic rats.(2) Analysis of experimental results and the experimental data, research framework - mixing tube in under cyclic loading the failure mechanism, hysteretic behavior, ductility, energy dissipation, stiffness, lateral displacement curves.(3) Using the finite element software ANSYS, specimens awakened nonlinear analysis, and results with the experimental data were compared to analyze the impact of the framework- mixing tube seismic performance factors.(4) Establishing a general framework - tube finite element model, and with the frame - mixed cylinder of the force - displacement curve, ductility, stiffness degradation, and other laws were compared to arrive at a clear framework - mixing tube than in the seismic performance General framework - the advantages and disadvantages of tube structure. And with the framework - cylinder test were compared.(5) With existing frameworks-a test tube tests results and the results of nonlinear finite element analysis, the framework-the seismic behavior and general mixing tube frame-tube seismic performance of good or bad.
