The block shear strength of connection is ________(a) block shear strength at an end connection for shear fracture and tension yield(b) block shear strength at an end connection for shear yield and tension fracture(c) larger of block shear strength at an end connection for (shear fracture, tension yield) and (shear yield, tension fracture)(d) smaller of block shear strength at an end connection for (shear fracture, tension yield) and (shear yield, tension fracture)I got this question in unit test.My doubt is from Behavior and Design Strength of Tension Members topic in division Design of Tension Members of Design of Steel Structures

Answer»

Right choice is (d) smaller of BLOCK shear STRENGTH at an END connection for (shear fracture, tension yield) and (shear yield, tension fracture)

EXPLANATION: The block shear strength of connection is smaller of block shear strength at an end connection for shear yield, tension fracture Tdb1 = (Avgfy/√3 γm0)+(0.9Atnfu/γm1) and block shear strength at an end connection for shear fracture, tension yield Tdb2 = (Atgfy/ γm0)+(0.9Avnfu/√3 γvm1).
