Collapse Mechanism and Full-Range Analysis of Overturning Failure of Continuous Girder Bridges

Table 1

Loading procedures in the models.

Model	Step 1	Step 2	Step 3
The solid model	Self-weight	Prestressing	Eccentric vehicle load , ..., applied incrementally until failure
The beam model	Self-weight	Prestressing	Eccentric vehicle load , applied at one time

Note: The loads created in one step were propagated in the subsequent steps.
