1.	Which of the following angle should be ideally used in bolted plate girder flange?(a) bulb angle(b) equal angle(c) unequal angle with short leg horizontal(d) unequal angle with long leg horizontalThe question was posed to me during an interview.I need to ask this question from Proportioning of Web & Flanges topic in portion Gantry Girders, Design of Plate Girders & Industrial Buildings of Design of Steel Structures
Answer» Correct answer is (d) unequal ANGLE with LONG leg horizontal To elaborate: Unequal angles with long leg horizontal are PREFERRED. It is because the moment of INERTIA of the section will be more and a large length will be AVAILABLE for making the connection with the flange plate.
