What are the sign conventions for forces/moments in beams ?
The sign conventions are as follows:
Axial (FX) : Positive = Along local X axis, Negative = Opposite to local XaxisShear-Y (FY) : Positive = Along local Y axis, Negative = Opposite to local YaxisShear-Z (FZ) : Positive = Along local Z axis, Negative = Opposite to local Zaxis
Torsion (MX) : Positive = Vector along local X axis, Negative = Vector opposite to local XaxisMoment-Y (MY) : Positive = Vector along local Y axis, Negative = Vector opposite to localY axisMoment-Z (MZ) : Positive = Vector along local Z axis, Negative = Vector opposite to localZ axis
For axial forces,
Positive at the start node indicates compression at the start node.Positive at the end node indicates tension at the end node.
Negative at the start node indicates tension at the start node.Negative at the end node indicates compression at the end node.
