Technical design
Technical design
Features
Schematization of the stability principle
Position of the supports on the frame
Application of the solicitations
Reaction on first oblique support
Positioning of the grating
Reaction on second oblique support and plane support
Positioning of the grating
Reaction on second plane support = equilibrium
Legend:
Blue arrow: Solicitations generated by the traffic.
Red arrow: Reaction force of the supports.
Green arrow: Resultant of the reaction forces.
Grey arrow: Positioning of the grating [Weak displacements to find stable supports].
The spring bar is not in permanent tension (passive bar) because it must not be opposed to the light displacement of the grating so that this one finds its supports.
