Question

Which of the following is correct during tension field action?

(a) web can resist diagonal compression

(b) horizontal component of diagonal compression is supported by flanges

(c) vertical component of diagonal compression is supported by flanges

(d) vertical component of diagonal compression is supported by stiffeners

I had been asked this question by my college director while I was bunking the class.

My question is from Plate Girders & General Considerations in portion Gantry Girders, Design of Plate Girders & Industrial Buildings of Design of Steel Structures

Answer 1

Correct option is (b) horizontal component of diagonal compression is supported by flanges

For explanation: As web begins to buckle , the web loses its ability to resist diagonal compression. The diagonal compression is transferred to transverse stiffeners and flanges. The vertical component of diagonal compression is supported by stiffeners and horizontal component is resisted by flanges. The web resists only diagonal tension and this behaviour of web is called tension field action.
