Shearing of Rivet: Thus shear strength is:

                       π
           P =  n( d )    for lap joint, single strap butt joint
                            2
             s
                   s
                       4
                         π
           P = 2  n( d ) for double strap butt joint
                               2
             s
                      s

       where,

           = allowable shear stress of the rivet material (S );
         s                                                                       s

       n = Number of rivets.





       Crushing of the Plate (or) Rivets: The

       crushing strength is:               P = s d t n
                                                   c
                                             c



       where,
                                                                                                       Maximum Shear Stress
       s = allowable bearing stress between the rivet and
         c
       plate material.                                                                                        =  1        2       2
                                                                                                             s   2      t   +    s
       n = No. of rivets under crushing;

       d = Diameter of rivet                                                                                                        147
