Torsion

Abstract

This chapter presents the design methods of RC elements subjected to torsion. After an introductory note on the stress distribution in beam elements as deduced from the basic structural mechanics, the peripheral truss model is described, with its more recent improvements, for the torsional resistance calculations of RC beams. The interaction of torsion with the other internal force components of bending moment, shear and axial action is treated for the actual design applications. In the final section, with reference to the overall stability of the building examined in the previous chapters, the calculation of the corewall system is developed under the pertinent horizontal actions.
