摘要
在海南省某桥的荷载试验中,采用有限元建立梁格模型计算桥梁横向分布系数,计算结果与实际桥梁荷载试验的测试结果进行了对比,两者结果相符,计算值与实测值之差在5%左右,在可接受范围内。此方法计算模型直观,建模过程简单,计算结果精度能满足应用要求。
In the loading test of bridge in Shanghai,finite element is used to establish beam-grid model for calculation of lateral distribution coefficient of bridge.After comparison,the calculation result matches the practical test result of bridge load test and the difference between calculated value and measured value is 5%which is acceptable.This method has legible calculation model and simple modeling process,and its calculation precision could satisfy the application requirements.
