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 lambda <= 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 lambda <= 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.
