| Abstract: | On the basis of construction practice,the project of erecting a prefabricated highway steel bridge on an existing bridge to temporarily strengthen the dangerous bridge to ensure the safe passage of special vehicles is proposed in the paper,with the specific structural forms of the steel bridge,and its inlet and outlet designed.The bearing capacities and rigidities of different structural styles are calculated,analyzed and compared by the software ANSYS,the result of the numerical simulation of which is comp... |
