Finite Element Analysis of Reinforced Concrete

Abstract

Cracking, crushing, and yielding of reinforced concrete beams is investigated by the finite element technique. Three-dimensional, 20-node isoparametric elements are used. The analysis incorporates the elasto-plastic behavior of concrete and reinforcing steel and the cracking of concrete stressed in tension beyond a limiting tensile stress. Shear retention in the cracking plane is also considered. The results obtained by this procedure compare well with those obtained experimentally and analytically.
