Abstract: A new analytical method of pin load computation for joints with multi-rivets or multi-bolts is presented by means of mathematical theory of elasticity and classical principle of structural mechanics.A system of linear algebraic equations of the unknown pin loads is estab- lished and several numerical examples are given. In this method, the connected plates are consid- ered as elastic bodies and not rigid ones,then the accuracy weakness of traditional method used in machine design can be overcome. Furthermore,the complicated finite element analysis due to the logrithmic singularity of displacements caused by pin loads can be avoided.This method has not only the advantage of computational convenience but also the availability for engineering application.

Key words: joint with multi-fasteners, pin load, analytical method of solution
