Ultimate shear capacity of bolt group.xls
This spreadsheet is using the instantaneous centre of rotation method to determine the ultimate shear capacity of bolt group. This method is described in LRFD Code (2nd Edition, Volume II, p. 8-28). In theory, the bolt group rotates around the instantaneous centre, and the displacements of each bolt is proportional to the distance to IC. Solving the system of three equilibrium equations we can find location of instantaneous centre and ultimate shear force of bolt group. Please, be aware of possibly wrong solution when instantaneous centre is too far from bolt group centre.
