A perfect truss satisfies the relation m = (2j – 3) where, j= number of joints and m=number of members (ii) Imperfect Truss An imperfect truss is one which does not satisfy the relation given by the equation m = (2j – 3) This means that the number of members in an imperfect truss will either be more or less than (2j-3).
