Abstract:
Using a softened truss model, this paper presents a method for torsional design of multicell concrete bridges. Earlier researchers have successfully shown the development for solving single cell torsion by combining the equilibrium, compatibility, and the softened constitutive laws of concrete. By solving the simultaneous equations based on the membrane analogy, multicontinuous or separate cells can be solved.
