Abstract
The purpose of this paper is to clarify the torsional properties of reinforced concrete members subjected to bending, shear and torsion. Firstly, theoretical expressions based on a space truss model are described.
This theory can predict not only the strength but also the angle of twist, the steel strains and the concrete strains throughout the loading history. Second, rectangular solid and hollow sectional reinforced concrete beams were tested in order to grasp the mechanical behaviours, that is, strengths, cracking patterns and deformations of such members. The presented analysis can predict very well the tested torsional behaviours.
