Study On Mechanical Behavior Of Steel Reinforced Concrete Special-shaped Columns Reinforced By Steel Plate

Steel reinforced concrete special-shaped column reinforced by steel plate is a new type of reinforced member which is composed of two parts: steel plate and reinforced concrete special-shaped column.Specially shaped column is a popular form of the column,and is widely used in new buildings.Steel plate and special-shaped columns are combined to give full play to their respective advantages.The steel plate reinforced concrete columns in the tensile zone can improve the mechanical properties of the concrete,improve the bearing capacity of members,and enhance the seismic performance.Relatively,the research on the mechanical properties of reinforced concrete special-shaped columns is scarce.In this paper,the finite element model of reinforced concrete special-shaped columns is established.As a kind of reinforced concrete special-shaped column,it is necessary to study the effect of cooperation between the steel plate and the concrete in the tension zone.Study on mechanical behavior of reinforced concrete special-shaped column reinforced plate,no prior research in related experiments and finite element simulation,this paper studies and describes the basic performance of reinforced concrete special-shaped columns are basic mechanical properties,the main research work includes:1.cross section design of reinforced concrete special-shaped columns.2.the finite element model of reinforced concrete special-shaped column is established by ABAUS,and the correctness of the model is verified.3.discuss the study and formulate the parameter effects on the mechanical properties of the component by changing the eccentricity,the ratio of the length of the limb,the thickness of the steel plate and the concrete strength of four factors,the bearing capacity of the special-shaped column is obtained.4.based on the results of ABAQUS analysis,and ultimately determine the eccentricity;limb length ratio;the thickness of the steel plate;the concrete strength of the four factors that influence the bearing capacity of steel reinforcement ultimate compressive mechanical properties of eccentric special-shaped columns of reinforced concrete.5.determine the reasonable eccentricity,the ratio of length to limb,the thickness of the steel plate,concrete strength.Suggestions for engineering design are put forward.
