CHAPTER 5 "TOOLS" 5 1.2 Fixed points Command to change the fixed top in the columns and the fixed span in the beams. How to use : Select the command and then point to the top of the pole you want to remain fixed. The fixed apex defines the point that remains constant in the case of massive dimensional changes in cross-section, material, etc. The initial position of the fixed point in columns is at their center of gravity. In the rafters you select the command and a small triangle marks the fixed axis which is the centrifugal axis. You select with the mouse the perpendicular that you want to remain constant. OBSERVATION: This command is very useful in the IMPROVEMENT of structures and allows to keep the points of the columns and the passages of the beams stable during the variations of the cross-sections. 1.3 Beam segmentation When you enter a continuous beam, the program automatically breaks it into individual beams where it meets columns or walls. This is because by default the switch is active. OBSERVATION: The command "Partition beam" has meaning only when is inactive. It is applied to the physical elements of the beams, i.e. before the mathematical model is created . In this case select the command and then the beam. EXAMPLE Suppose you have a row of five (5) columns as shown in the picture
