high-s位ength hoop stress ∞mpetence of muscle. On the basis that the high-由ength
∞ponent is shear mechanism analyzed,the existing armored concrete
∞mponent of survey is shωr the strength of bearing the weight of analyze tbe model, according to the theory of the press町e field of revision,consider the high-strength Stirrup
restrains this position model of the high-由ength concrete,have proposed 也e short column based on field theory of the revision pressure is shear the strength of bearing
the weight of calculate the formula, compared with test result,indicate calculation
formulae put forward are partial to the security. Based on test result of this text, study the
∞,ncrete intensi凯 it shear it step until,血le pigeonhole th钮,Stirrup intensity,and Stirrup
岛rm,etc. restrain ∞ncrete columns shorts high-s位ength from shearting into influence ω
bear the weight of s位engthωStirrups high-strength rate of hoop mixed ,indicate,shear, step than and to influence high-strength Stirrup restrain high咄ength concrete short column from shear into performance main two factor in grade in intensity in concrete.
Uti1ize the high-streng也 Stirrup to restrain the test data of the high-strength ∞ncrete short
column,puting technology bining currently and normally,the short column is shear the strength of bearing the weight of calculate formulae practically to adopt the statistical method of mathematic s and physics and 缸, identical better with the
1est result. Fina11y,formulae and structural design specification of ∞ncrete of our ∞m町
that the high-strength Stirrup putting forw缸d this text restrains high-strength concrete short column from being calculated ,computing technologies such as .'s norm, Japan's norm,etc. have pared,puting technology that the structural design specification of concrete of our coun'町 provides is p甜ial to unsafely. The research results
ofthe thesis can be for project reality's reference.
