Subject: Definition of Global and Local Coordinate System and Element End Force Directions Coordinate System 1- Axes according to the Global coordinate system 2- Axes and end force directions according to the local coordinate system a) Beams b) Columns and curtains Coordinate System[/ size] Axes According to the global coordinate system, the plus (+) direction is upwards, with the Z axis being the vertical axis (axis perpendicular to the paper plane). If the constant weight is G, then Z is downwards in the negative (-) direction. The X axis is the left to right direction on the paper plane, plus (+) direction. The Y axis is the other axis perpendicular to the X axis in the paper plane and the positive direction is determined according to the right hand rule. The project (build base) can be at any point on the pivot assembly. Axes and end force directions Beams When looking at a beam in the plan, axis 1 parallel to the beam, axis 3 axis perpendicular to it in the plan, and vertical axis 2 axis perpendicular to the working plane should be considered. Left end is i, right end is j. Columns and walls In columns and walls, similarly, the 2 axis showing the strong direction of the column, the 3 axis showing the weak direction, and the vertical axis 1 perpendicular to the working plane should be considered. The lower end is i and the upper end is j. The subject has also been added to the message as a pdf document.
