Experiments with Concrete in Torsion

Abstract

Torsional stresses are developed in a structural member if it is subjected to the action of couples that lie in planes perpendicular to its axis. In the ordinary building frame, provision seldom is made for taking care of stresses of this nature, and current literature on the design of reinforced concrete structures contains little on the subject. The attitude of the designing engineer is to avoid torsional stresses rather than to take them into account; and as a rule they can be avoided quite successfully.
