A simple approximate step-by-step method is proposed for the nonlinear analysis of fastener groups subject to eccentric shear. The procedure replaces the traditional trial and error solution by a series of incremental linear elastic analyses. Rigid plate-piecewise linear bolt model is assumed. Conservative, yet sufficiently accurate results may generally be expected. With this approach it is possible to trace the development of plastification and the migration of the incremental instantaneous center of rotation with increasing loading.
