The distribution of load among fasteners in a butt type wood joint, in which the main member is loaded perpendicular to its grain has been studied analytically. Using a computer mathematical model, the effect that the joint variables of load-slip modulus of bolts, spacing of bolts in a row and relative member stiffness has on the distribution of load to the bolts in a row has been studied for joints with steel and wood side plates. The results show that the load is not equally distributed among bolts in a row for joints with both wood and steel side plates. In all cases studied, the bolt nearest the unloaded edge of the joint (first bolt in the row) carried the largest force and the last bolt in the row carried the smallest force. This phenomenon is probably primarily due to the stiffness of the main member being considered less than that of the two side plates. However, changes in bolt spacing and the load-slip modulus for the bolts also contribute to make the distribution of load among bolts uneven.
