10B. DIMENSIONING PART 2/4

CHAPTER 10B 'DIMENSIONING' 75 5.2.1.1.1 Instructions for inserting support lines on flat slabs - Support lines should start from a support post and end at a support post (or free end). In all cases they must include at least one support post. - The support line should only reach the contour of the plate when it is free edge. Otherwise it may stop at the contour or at the node of the column. - When the boundary conditions (i.e. what lies to the right and left of the support line) change along its length, the line must break at these points. For example in the following case on support Line 27, its red right area was not formed correctly (it is the red sloping line). This happened because a support line was inserted that: At the top of the right side it is bordered by a beam, i.e. the boundary of the slab, so the program has defined the red outer area at the boundary of the slab (point 1).
