| Abstract: | The crack behaviors of two Partially Prestressed Concrete (namely PPC) continuous box girders of 3-span with varied depth are designed and tested. Analysis is made on the test results. Consequently, the test data indicates that in comparison with four formulae calculating crack width, the formula may be used for designing and calculating the crack width of PPC continuous girder. |
