Finite Element Analysis Of The Steel Reinforced High Strength Concrete Column

Steel reinforced high-strength concrete is a combination of steel and high- strength concrete. It is a new way for development of steel structures and concrete structures.The columns in the basement of the high rise building and the super tall building bear huge axial compression, if the high-strength reinforced concrete columns are still applied in the high-rise building, it will not only affect the columns'function, but will also shape short columns whose seismic behavior is poor, for limits of axial compression ratio will increase the size of columns section. It is well known trough lots of experiments that steel reinforced concrete columns can effectively reduce the axial compression ratio of columns concrete part and improve the seismic behavior of the columns because the steel skeletons in the columns can take part of the axial compression.As a result, reinforced high concrete columns, especially for the steel high-strength reinforced concrete columns, are applied widely in modern construction. But now we have very few research data in column seismic ductility, for it will cost a lot of money and continue a long time to derivative the seismic behavior of the columns through experiments.As one of the general structure analysis methods, the finite element method can imitate performance of the composite beams with a lot of changing influence factors, and provide lots of analysis data to found a basis for design. In order to seek a more economic and reasonable method to investigate the seismic behavior of high-strength reinforced concrete columns, I had a part in the experiment and analyzed the data by finite element analysis software ANSYS build up mathematical model to analyze the failure patterns, strength, seismic behavior in contrast with the result of experiment, and finally discuss the limits of axial compression ratio apply to engineering.
