Mechanical Performance And Design Method Of Steel Reinforced Concrete Column

Steel reinforced concrete structure is in the concrete configuration solid-web or hollow section steel, and is equipped with stirrups and longitudinal reinforcement of structure,referred to as SRC structure, SRC structure makes the compressive performance of concrete and steel tensile performance can be very good play, can effectively solve the shortage problem of the tensile performance of concrete, due to compression of concrete can take the place of some steel under pressure, and can save steel to achieve good economic benefit.Because the steel reinforced concrete structure has many advantages, is better than that of ordinary concrete structure and steel structure, in recent years more and more get the attention of the countries all over the world.Steel reinforced concrete structure has become more and more widely used in large-span structure, the structure of the high-rise buildings and towering structure, especially in seismic zone, building structure.This paper on the characteristics of the steel reinforced concrete structure and the research and development situation at home and abroad are introduced briefly, and then studies the axial compression ratio for steel reinforced concrete column precscribed,reinforced concrete column and steel reinforced concrete column were analyzed the relationship between the axial compression ratio, with large and small eccentric limit balance condition, on the basis of deriving the axial compression ratio of steel reinforced concrete column precscribed formula.On the bearing capacity of normal section and inclined section steel reinforced concrete column are studied, and the calculation method of contrast for the domestic and foreign relevant code and summarized.Second, the eccentric loading the second-order effect of steel reinforced concrete column were analyzed, and study its effect on the bearing capacity of SRC column, and the increase of eccentricity coefficient of SRC column theory analysis, summed up the research achievements of domestic and foreign scholars in this area.And using the finite element analysis software ANSYS to two groups of coaxial compression ratio and stirrup ratio of steel reinforced concrete column under low reversed cyclic loading is finite element analysis.Finally, the numerical simulation results are in no axial compression ratio and stirrup ratio different cases, the load - displacement curve of steel reinforced concrete column, the hysteretic curve and skeleton curve, and analysis of axial compression ratio and stirrup ratio on the mechanical performance of steel reinforced concrete column.
