Consequently,instead of considering this from a theoretical standpointalone, safe values for the bending moments may be selected,based on general principles of mechanics and qualified byactual tests. Let li = distance between lines of inflection. This dis-tance will be about 3/5 of the net span between columnheads April 4, 1912. THE CANADIAN ENGINEER 495 For the rectangular reinforcement, if the slabs betweenthe points of inflection were simply suipported, we shouldhave a moment of wliV<^- However, the bending momentin the Minneapolis tests, based on the maximum stressesunder uniform working load is about wliVsS- It wouldappear amply safe, therefore, t
