【摘要】 对部分预应力混凝土 (PPC)连续梁 0号块节段模型进行试验研究 ,确定实际桥梁对应的截面的使用性能和极限承载力。对试验结果的分析表明 ,随着载荷水平的增加 ,截面的剪力滞效应逐渐明显。用常规的箱梁剪力滞效应对试验结果进行的计算分析结果表明 ,通常采用解析求解箱梁剪力滞的分析方法有待于进一步的改进 ,对于大跨、新型桥梁结构的分析评价应包含其剪力滞效应更多还原

【Abstract】 Test study for model of Segment No.0 of a partial prestressed concrete (PPC) continuous girder was made in order to check the serviceability and ultimate carrying capacity of the corresponding section of the actual bridge. Analysis of the test results indicates that with increase of the load levels, the shear lag effect of the section will become gradually obvious. The results calculated by means of regular formula for calculating the shear lag effect in box girder show that the usual analytical solutions for the shear lag effect remain to be improved. When structural behaviors of large span and new type of bridges are analyzed and evaluated, their shear lag effects should be considered also.更多还原
