Principle Of Suspension Bridge

The greatest force in a suspension bridge is the tension in the suspension cable and the pressure in the tower. Since the tower is basically free of lateral force, its structure can be made quite slender. In addition, the suspension cables have a certain stabilizing effect on the tower. If the weight of the suspension cable is ignored in the calculation, the suspension cable forms a parabola. In this way, the process of calculating the suspension bridge becomes very simple. The suspension cables of old suspension bridges are generally iron chains or iron bars connected together. Modern suspension cables are generally multi-strand high-strength steel wires.
