Experiment by authors showed that lateral strain at the center in a real size column using ultra high-strength concrete was larger than longitudinal one. This phenomenon indicates that stress, which may cause longitudinal crack, is produced in the RC column when the isotropic autogenous shrinkage is assumed. Based on this experimental facts, 3-dimensional finite element method which takes account of temperature dependent autogenous shrinkage is conducted for evaluating stress in the RC column. As a result, it is numerically confirmed that temperature history and autogenous shrinkage produces self-induced stress in cross-section which is vertical to longitudinal direction of RC column.
