| Abstract: | In order to overcome the shortcomings of simply supported girder bridges constructed with continuous pavement, the structure of simply supported-continuous system is applied in bridges with multiple medium-spans. The styles of its structural system, the lateral effect of prestress and the creep effect are studied. Results of model tests and engineering practice are also analyzed. |
