Shear strength of bolt is given by ____(a) fu(nnAnb+ nsAsb)/(√3 x 1.

1.	Shear strength of bolt is given by ____(a) fu(nnAnb+ nsAsb)/(√3 x 1.1)(b) fy(nnAnb+ nsAsb)/(√3 x 1.1)(c) fu(nnAnb+ nsAsb)/(√3 x 1.25)(d) fy(nnAnb+ nsAsb)/(√3 x 1.25)I had been asked this question in an interview.Question is taken from Bolted Connections in division Bolted Connections of Design of Steel Structures
Answer» The CORRECT choice is (c) fu(nnAnb+ nsAsb)/(√3 X 1.25) Explanation: Shear strength of BOLT = fu(nnAnb+ nsAsb)/(√3 x 1.25), where fu=ultimate strength of bolt, nn=number of shear PLANES with thread intercepting shear plane, ns=number of shear planes without thread intercepting shear plane, Anb=nominal PLAIN shank area of bolt, Asb=net shear area of bolt at threads.
