Abstract |
Both shear and torsional moments apply shear stresses on cross-section of a member, which need to be considered in the design. But in the current Korean Building Code, the design equations for shear and torsional moments are expressed in terms of the sectional strength with different units, causing figures to be drawn separately in two axes. If the design equations are expressed in terms of stresses, then the stresses of shear and torsional moments can be added, allowing figures to be drawn in one axis for easy recognition of the design procedure and the final design results. Moreover, the current code’s design equations for shear and torsional moments are considered separately with the intention of summing the area of stirrups with respect to unit length for shear moment (Av / s) and torsional moment (2At / s). Since the size or type of vertical stirrups are predetermined in the design process, the design equations are expressed in terms of the spacing of stirrups rather than the Av / s and 2At / s terms, clarifying various design steps and a design process.
