Response and Design for Shear and Torsion

Abstract

The behavior and design of cross-sections for shear and torsion in the focus of this chapter, with emphasis on reinforced concrete sections. The elastic response of cross-section is first demonstrated through equations, as well as graphical representation of stresses in concrete, steel, and composite section. This is followed by the postcracking response of concrete sections for shear and torsion. Equation is developed and described to demonstrate the basic behavior, leading to the development of simplified procedures used in various design loads, specially ACI. Several detailed flowcharts are included to demonstrate the procedures used in ACI, BS, and Euro codes for design of cross-section subjected to shear and torsion, followed by solved examples.
