Steelwork

6.5.7Examples

1 Using information about the supported wall and Table 1:

  • load per metre run = 4.2kN/m

2 Using the load per metre run, the span of the beam and Table 2:

  • suitable section size = 178 x 102 x 19 UB

152 x 152 x 23 UC is not suitable as it is too wide for the inner padstone/wall.

3 Using information about the wall supporting the beam (100mm thick), the walls supported by the beam
(medium density block) and Table 6:

Notes

1 This is greater than the flange dimension of the steel section obtained in 2 above – 102mm – therefore a padstone is required to distribute the load.
2 The actual length and depth of a padstone could be greater to suit masonry coursing.
