► A user-defined finite element for modelling bolted composites joints is presented. ► The element represents non-linear load-displacement behaviour of single-bolt joints. ► A combined analytical/numerical approach is used to formulate the element. ► The method is used to model the load distribution in twenty-bolt joints. ► The method was found to be robust, accurate and highly efficient.
