Which of the following equation is correct for bolt subjected to combined shear and tension?(a) (Vsb/Vdb)2 + (Tsb/Tdb)2 ≤ 1(b) (Vsb/Vdb)2 + (Tsb/Tdb)2 ≥ 1(c) (Vsb/Vdb) + (Tsb/Tdb) ≤ 1(d) (Vsb/Vdb) + (Tsb/Tdb) ≥ 1This question was posed to me during an interview.The above asked question is from Bolted Connections in portion Bolted Connections of Design of Steel Structures

Answer»

Right ANSWER is (a) (Vsb/Vdb)2 + (Tsb/Tdb)2 ≤ 1

To elaborate: Bolt required to SATISFY both shear and tension at the same time should satisfy (Vsb/Vdb)2 + (Tsb/Tdb)2 ≤ 1 , where Vsb= FACTORED shear force, Vdb = design shear CAPACITY, Tsb = factored tensile force, Tdb= design tensile capacity.
