Analysis Of Mechanical Properties Of L Reinforced Concrete Columns

L-shaped reinforced concrete column means a column whose section geometric shape is L and ratio of limb-length to thickness is lower than 4.It has been utilized extensively since 70 s of 20 c with its advantages of improving constructions' function,lightening structural gravity,increasing area of structure.It has broad prospects and research significance.This essay builds analytic module of L-shaped reinforced concrete column,compares with experimental conclusion and matches well,and have verified the rationality of the module built,which is based on previous experimental research of reinforced concrete compression column.At first,this essay builds analytic module of L-shaped reinforced concrete column,aiming at the mechanical property of reinforced concrete compression column,and discusses the influence of parameter to mechanical property through changing the concret e strength,the slenderness ratio,the reinforcement ratio and stirrup ratio.Then,this essay builds analytic module of L-shaped reinforced concrete column,aiming at the mechanical property of reinforced concrete compression column,and determines the decision condition of small eccentricity or big eccentricity;This essay also discusses the influences from the load loading angle,eccentric distance,the slenderness ratio,the reinforcement ratio and the volume-stirrup ratio to the lower bound eccentricity under the condition of small eccentricity,big eccentricity and L-shaped reinforced concrete column,aiming at the mechanical property.
