How this node works
The tendon is not straight: it is draped in a gentle curve, low at mid-span and high over the supports, held to that exact profile by bar chairs. The shape is the whole point — its upward pull «lifts» the slab against the load and counters the deflection. Ordinary reinforcement still runs top and bottom.
