with a beam span of 4 meters and end bearings of 200mm each when calculating the shear on the padstones from loads do i use the span of 4 meters or the 4.4 meters for calculations.
What is a padstone? Is that the same as a footing?
For purposes of calculation, the span of the beam is the distance from center to center of bearing. If the clear span is 4m and the bearing at each end is 200mm, then the effective span is 4.2m.
