| Abstract: | The conventional integral bridges have some structural problems which limited its applications.In this paper,a new type semi-integral bridge is developed which combine the advantages of traditional joint-bridges and integral bridges.The successful operation of five semi-integral bridges in China proves that this new type semi-integral bridges is easier to design and construct,and all have good operation,therefore the bridge is recommended to be constructed in large scale. |
