Terenez bridge cable-stayed bridges actually are very different from suspension bridges in principles and method of construction. In a suspension bridge, the long cables are the primary load-bearing structures that are mainly responsible for the function of the bridge; for a cable-stayed bridge, the pylons form the primary load-bearing structures. For a bridge span of medium length, like that of Terenez Bridge, a cable-stayed design is optimal from both structural and economic perspectives. Since the cables of Terenez Bridge will not be exerting large horizontal tensile forces on the anchorages, construction of the bridge does not require excellent soil conditions. The deck
Pontoon effect Pontoon effect The pontoon effect refers to the tendency of a vessel whose flotation depends on lateral pontoons to capsize without warning when a lateral force is applied. The effect can be sudden and dramatic because pontoon boats usually cannot rely on the righting effect of a keel (which contains ballast). The vessel is stable and self-righting up to the point that the centre of gravity shifts past the centre of buoyancy of the ship and the vessel rapidly capsizes. The pontoon effect is theoretically possible whenever the vessel's entire weight exceeds the buoyancy of the pontoon(s) on either side.
