EXAMPLE 3: 'DESIGN OF A METAL STRUCTURE' 32 3.1.6 Matching members The next step is to define the zones. This is to determine the distribution of pressure (wind and snow) on the structural elements of each facade and roof. Select for the wall and roof members the influence zones, i.e. the width of the pressure surface, Left and Right of the member and make on the members of the member you want to assign. The Left and Right widths are referenced to the local x-axis (the longitudinal) of the member. We are assumed to be at the member's start node (i) and looking at the end node (j). In detail : For example, if you want to set the zone of influence of a Wall Left pole: First you need to know the width of the zone that the two successive poles will share. With the help of the Tools and the "Length-Angle" command, measure the distance between the two poles (dZ=190cm):
