Abstract
3-D solid linear FEM analysis is now becoming a common method in design of large scale RC structures, however, there is no widely accepted design method available so far, in which 3-D solid linear FEM analysis is applied especially to determine appropriate amount of reinforcement. This paper proposes a new method to calculate the required amount of reinforcement using element stresses obtained in a 3-D solid linear FEM analysis. Several examples demonstrate a practical application of the method to a design. An investigation on a recently proposed design method for shearing force is also presented along with some other methods.
