For stiffeners PQ (running along the beam axis) and RS (running between the top and bottom flanges), which of the following pairs of statements will be TRUE?

  1. (i) RS should be provided under the concentrated load only.
    (ii) PQ should be placed in the tension side of the flange.
  2. (i) RS helps to prevent local buckling of the web.
    (ii) PQ should be placed in the compression side of the flange.
  3. (i) RS should be provided at supports.
    (ii) PQ should be placed along the neutral axis.
  4. (i) RS should be provided away from points of action of concentrated loads.
    (ii) PQ should be provided on the compression side of the flange.
