| Abstract: |
Bridge is such a structure, whose service life expectancy is more than 100 years. Any steel bridge may give such durability provided the factors influencing the durability are controlled properly. Experience shows that durability of steel bridges has substantially been extended by taking preventive measures to resist deterioration of structures during its service life. Case study of some durable steel bridges of India which have given service life beyond expectation, have been highlighted here. Development of steel as structural material as well as technology of steel bridge (construction and maintenance) has been taking place since the middle of 19th Century. The paper highlights how these developments related to selection of material, design technique, fabrication/erection methodology, maintenance approaches and authorities’ policy helped in achieving higher durability in case of steel bridges. It is concluded that though the durability of steel bridges is about 100 years, it can further be enhanced with the implementation of new technological concepts and knowledge. |
