1. Prestressed members can be either pretensioned,i. e. the tendons are stressed before the concrete is cast around them and the force transferred to the concrete when it has obtained sufficient strength,or post-tensioned,i. e. ducts are cast into the concrete through which the tendons are ...

in China started late. Before the 1950s, many bridges were invested, designed, and constructed by foreigners. Most highway bridges were made up of wood. After the 1950s, China’s bridge construction entered a new era. In 1956,the first prestressed concrete highw 正在翻译,请等待...[...
Need of Pre-stressing To offset the deficiency of tensile strength in concrete, steel reinforcement is provided near the bottom of simple beams to carry the tensile stresses. ADVANTAGES OF PRESTRESSED CONCRETE 1. Durability As this technique eliminates weakness of concrete in tension, such members re...
