| Abstrait: |
The effect of the new Eurocodes on the design of prestressed concrete box-girder bridges is investigated. The Moment/Stress plot is introduced to display the combined effect of many different clauses. Its use together with economic data from current projects leads to a surprising result. Even for quite long span structures it will be more economic to use reinforced concrete instead of prestressed concrete as currently used. The subject is discussed. |
