Cable stayed solution

The solution of cable-stayed bridge by OVM – is based on the application of steel strand cable, steel wire cable and the whole bunch of extruded cable. OVM has provided products and special construction service for over 100 cable-stayed bridges in the world.

The main structural elements of a cable stayed bridges are the bridge deck, piers, towers and the stays. The deck supports the loads and transfers them to the stays and to the piers through bending and compression. The stays transfer the forces to the towers, which transmit them by compression to the foundations.

Features of Cable Stayed System

➤ Different requirements, bar/galvanized/epoxy coated strand, or galvanized/epoxy coated steel wire can be selected as the material for cables.

➤ High performance of anti-fatigue with 250Mpa stress amplitude.

➤ Good anchorage safety performance under low stress.

➤ High anticorrosion performance by use of epoxy coated steel strand or steel wire cable.

➤ Excellent multilayer anticorrosion protection ensure the system to meet requirements of CIP, fib.

➤ Simple structure and easy installation, engineering service is available.

Components of Cable stayed

The suspension system is usually one of two main types, with the stays anchored to the top of the tower (Fan) or the anchors are distributed along the length of the tower (Semi-Fan and Harp). This system directly affects the level of axial load and the elastic support given to the deck and to the tower.

The static system of a cable-stayed bridge can vary due to the conditions of support of the deck at the abutments and the whether there are piers in the side spans. The connection between the deck and the tower is also of great importance. This system primarily affects how effectively the structure carries live loads.
