摘要
介绍了通过模型试验研究大跨径桥梁部分预应力砼连续梁的裂缝行为的方法。对模型试验的工作过程进行了详细说明,并对试验结果进行了分析。通过试验数据与理论计算值的对比,总结了理论公式的适应范围。
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.
