The Analysis of Judging Criterion and the Influence of Shear-Span Ratio to the Failure Model in Frame Short Column

In architectural design, the discrimination to the frame short column has two judging criteria: the judging criterion with the shear-span ratio λ«2 and the judging criterion with the height-width ratio H/h«4 . Whether they have consistency has been raised attention by the engineering personnel. Through the analysis of two judging criteria, We get that: the judging criterion λ«2 has extensive applicability; the judging criterion H/h«4 is the simple calculation method, and needs certain limitations. Meanwhile, by the analysis of the relationship between the shear-span ratio and the mechanical properties in frame short column, it is concluded that the shear-span ratio has the directly affect to the failure model, and the circular cross-section frame column has better mechanical properties.
