The block shear strength at an end connection for shear fracture and t

1.	The block shear strength at an end connection for shear fracture and tension yield is given by :(a) (Avgfy/√3 γm0)+(0.9Atnfu/γm1)(b) (Atgfy/ γm0)+(0.9Avnfu/√3 γm1)(c) (0.9Avgfy/√3 γm0)+(Atnfu/γm1)(d) (0.9Atgfy/√3 γm0)+( Avnfu/γm1)The question was asked during an interview.The doubt is from Behavior and Design Strength of Tension Members topic in section Design of Tension Members of Design of Steel Structures
Answer» Right option is (b) (Atgfy/ γm0)+(0.9Avnfu/√3 γm1) The best explanation: The block shear strength at an end connection for shear fracture and TENSION YIELD is GIVEN by Tdb2 = (Atgfy/ γm0)+(0.9Avnfu/√3 γm1), where Avn = minimum net area in shear along line of action of force, Atg = minimum gross area in tension from hole to toe of angle or last row of bolts in plates perpendicular to line of force, fy and fu are yield and ultimate stress of material respectively, γm1 = 1.25, γm0 = 1.10.
