Performance of Cable Supported Bridges During Earthquakes

Cable supported bridges perform better during earthquakes compared to other types of bridges. There are seismic weak points in cable supported bridges which are likely to become source of damages when the structure experiences an earthquake. It is thought by most bridge ...

BALANCED CANTILEVER METHOD OF BRIDGE CONSTRUCTION

Balanced Cantilever method of Bridge Construction: Balanced cantilever method of bridge construction is chosen where a bridge has few spans which range from 50 to 250m. Construction begins at each bridge pier. Special formwork is positioned and cast-in-situ pier segment is ...

METHODS OF BRIDGE CONSTRUCTION

METHODS OF BRIDGE CONSTRUCTION: Before a bridge can be built an appropriate method of construction must be chosen. The decision is made by the design team. The principle factors considered by the design team when chosing a suitable method of construction ...

ADVANTAGE OF CONTINUOUS OVER SIMPLY SUPPORTED MULTI-SPAN DECK

Advantages of continuous multiple-span deck over simply supported multiple-span deck Movement joints are normally added to bridge structures to accommodate movements due to dimensional changes arising from temperature variation, shrinkage, creep and effect  of prestress. However, the provision of excessive ...

INSPECTION OF A BRIDGE STRUCTURE

INSPECTION OF A BRIDGE STRUCTURE: Once a bridge is opened for use, management begins and carries on for the life of the bridge. Hence, the bridge must be regularly inspected and maintained for the benefit of its users. There are three levels ...
