1.	What is the expression for Ψ in the fv for nominal shear strength according to tension field method is given by(a) 1.5 τb sin2φ(b) sin2φ(c) 1.5 τb(d) 1.5 τb /sin2φThe question was asked during an interview.The question is from Web Panel Subjected to Shear in division Gantry Girders, Design of Plate Girders & Industrial Buildings of Design of Steel Structures
Answer» The correct answer is (a) 1.5 τb sin2φ The EXPLANATION: The VALUE of Ψ in the FV for nominal shear strength according to tension field method is given by Ψ =1.5 τb sin2φ, where τb is buckling strength or shear stress corresponding to web buckling, φ is inclination of tension field which DEPENDS on DEPTH of web and spacing of stiffeners.
