Study Of Column In High Strength Steel Reinforced Concrete

Steel Reinforced Concrete structure is composite structure which Reinforced Concrete embraces steel. High strengthen Steel Reinforced Concrete structure adapts low alloy and high strengthen steel. High strengthen steel yield strength is defined up Q400 present. High strengthen Steel Reinforced Concrete structure not only has a lot of merits of Steel Reinforced Concrete structure such as: high load-bearing, big stiffness, good resisting seismic, good ductility, good fire resistance but also effectively reduces member cross-section to improve load-bearing.This paper systemically does experimental analysis theoretical analysis to High Steel Reinforced Concrete Column. First, the compression force of High Steel Reinforced Concrete Column is axially analyzed. The results shows the destructive process of it is different to the common Steel Reinforced Concrete Column, whose of ultimate bearing pressure formula isn't fit to High Steel Reinforced Concrete Column, This paper improves an new theory regressive formula. secondly High Steel Reinforced Concrete Column are eccentrically analyzed, The results show the destructive characteristics are different to the common, but its ultimate bearing pressure is calculated by plane assumed. This paper regresses the formula of High strengthen Steel Reinforced Concrete eccentrical column according to the formula of even material eccentrical column. Third, the shear property of High Steel Reinforced Concrete Column is analysed and get the destructive mechanism similar to the common, however, carrying capacity is improved high lightly, and code formula is too conservative. This paper deduces the resisting shear carry capacity as Steel Reinforced Concrete is occurring bonding destruction according to its destructive mechanism. Finally, theaseismatic properties of High Steel Reinforced Concrete are analysed, The results show its ultimate elastic-plastic deformation displacement angle, looping ring area, the stabilization of carrying capacity after bending, bonding and sliding property, rheostriction et are not largely different to the common members of Steel Reinforced Concrete, but whose of absorbing engentic capacity is better than the common members, since High Steel Reinforced Concrete increase the carrying capacity ,while its deformation is similar to the latter ,resulting in its PA increasing.This paper analyzes the properties of High strengthen Steel Reinforced Concrete column by ANSYS.
