The effect of the nonuniform drying shrinkage on the deformational behavior of concrete is investigated by the finite element analysis with concrete elements. A concrete element is a kind of complex element made up of a number of finite elements to represent the inhomogeneous internal structure of concrete. From the numerical simulation for a num­ ber of model concrete specimens subjected to drying, the distributions of moisture and cracking are obtained. Then, the amount of cracks which indicates the damage of concrete is statistically analyzed.
