How to calculate the axial force of steel support in subway construction
The cross section (in the building curtain wall, the special frame supporting curtain wall, also expressed as eccentric compression and eccentric tension). Usually: force with positive sign, pressure with a negative sign.
Axial force: in architecture, the internal force which coincides with the axis of the rod is called axial force, which is represented by the symbol FN. When the bar is pulled, the axial force is Tension, which points away from the cross section; when the member is pressed, the axial force is the pressure (Compression)
The design of pre axial force (force along the direction of the line per meter of straight brace under the action of the steel support) multiplied by the length of diagonal bracing axial force for the same spacing of straight brace 1/sin alpha times. The angle between the axis and the axis of the crown beam.
