摘要
简支转连续箱梁桥是现今公路与城市道路桥梁中一种常用的桥梁结构形式。在结构体系转换前单根小箱梁裸梁是处于简支状态。本文提出一种确定简支转连续小箱梁裸梁静荷载试验加载内力的计算方法,并采用加载块等效的方法对小箱梁裸梁进行静力荷载试验加载,对裸梁承载能力进行了评定测试与评估,结果表明,计算方法与试验满足评估要求。
Simple supported continuous bridge is now commonly used in highways and urban roads.Before the structure transformation,the single box girder is simply supported.A calculation method was brought forward in this paper to determine the static test load of simply supported continuous box girder,and the equivalent loading method was applied to loading during the test.Evaluation was made to the bearing capacity of the single beam.The results show that the calculation and experiment can meet the requirement of the evaluation.
