Abstract

A new computation procedure is developed to predict the overall behaviour of reinforced concrete beams under torsion. This procedure is based on a modification of the classic Variable Angle Truss-Model in order to make it capable of predicting the behaviour of the beams under torsion for all loading states. The theoretical predictions are compared with the results from reported tests. Conclusions are presented. The main conclusion is that the new procedure described in this paper gives very good predictions when compared with the actual overall behaviour of the beams.
