CHAPTER 2 "MODELLING" 14 2. Beams Η team command team "Beams" includes the commands for to model beams from: - Concrete - Metal (Hot & Cold Rolled) and - Wood Each command includes the corresponding sub-commands that define the type and shape of the cross-section. Define the parameters of the beam. More specifically: 2.1 Concrete beams • " Cross-section ": select the type of material (Concrete / Steel / Wood) and the quality. Then, from the standard cross-sections displayed according to the type of material, select the type of cross- section • " Geometry ": enter the dimensions of the cross-section based on the graph showing the shape of the beam. In the window, the cross-section of the beam is formed based on the geometry you have selected and the dimensions you have entered. Here you can also see the local yy and zz axes of the cross-section The four buttons set the angle of the beam in degrees, changing its orientation by 90°, 180° and 270°. • " Angle ": enter the value of the angle of rotation of the beam for angles other 0, 90, 180 or 270°. The angle of rotation refers to the local axis xx of the beam angle Beta). For example, if the angle of rotation is 45º, the beam is placed based on the figure:
