Q.

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
Answer» B. horizontal component of diagonal compression is supported by flanges
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.
