The spreadsheet allows to verify bolted connection using standard technical literature and Eurocode norms. It gives some tools for a complete design of a bolted joint reported in different woorksheet sections: - Calculus of bolt distances from edges - Verification of the bolted joint at Eurocode EN 1933-8 both in shear and friction modes. It allows to verify up to 6 connected plates providing the results separated tables depending by the joint categories (A, B, C and D) as per EN 1933-8 - Complete dimensioning of bolted connections using standard and Eurocode norms taking into account the stiffness of the connected plates to evaluate the forces distribution between bolts and flanges and tightening torque parameters. Bolts in shear and friction modes with one or two shear sections. It allows also to design the case of bolt in threaded holes. - Calculation of tightening torques and bolts parameters in table format - Listing of the minimum clearances needed for practical screwing operations
