1: Can RCDC design RCC columns for torsion effect (torsional moment or moment about longitudinal axis) ?
2: As per which clause of Indian code used for the same, as Indian clause not clearly say for design of columns for torsion.
3: Does RCDC incorporate the effect of torsion in combined interaction ratio or utility ratio ?
Hi,
RCDC do not design column for torsion. As you rightly mentioned, there are no clear guidelines to design of column for torsion moment.
