Influence of Membrane Forces on Transverse‐Shear Reinforcement Design
Publication: Journal of Structural Engineering
Volume 120, Issue 4
Abstract
A procedure is presented for the design of transverse reinforcement in concrete slabs and walls subjected to combined transverse shear, membrane forces, and bending moments, such as what commonly occurs in ice walls of concrete offshore structures. The slab or wall is treated as an equivalent beam in the principal transverse‐shear direction, and a unified shear‐design procedure based on the modified compression field theory is used to design the reinforcement. The method includes a rational concrete contribution, making it suitable for members with little or no transverse reinforcement. The biaxial membrane strains at the level of the flexural tension reinforcement are estimated using a generalized truss (sandwich) model, assuming cracked‐linear response of concrete. The normal‐strain component in the principal transverse‐shear direction is assumed analogous to the longitudinal strain in a beam. Comparisons of the proposed design method with a complex three‐dimensional analysis model and some recent experimental results show very good agreement.
