A two-dimensional composite element is developed in this study that is capable of predicting the out-of-plane interlaminar shearing stresses between the brick and block wythes without using a three-dimensional finite element model. This composite element is utilized in two-dimensional analyses in a plane-strain condition. The results of these analyses are compared with those using the plane-strain finite element models. These comparisons indicate that the two-dimensional composite element models predict interlaminar shearing stresses in the collar joint that are in good agreement with those obtained from the plane-strain models. Although the composite element is initially developed for only elastic conditions in an unreinforced collar joint without any consideration to fracture and failure, these criteria can be easily incorporated in the proposed model.
