桥梁结构基于校验系数损伤程度的研究

Bridge Structure Based on Calibration Coefficient of Degree of Damage

利用ANSYS结构有限元动力分析计算,研究了完好及不同破损程度下混凝土梁的校验系数和频率的变化规律。通过对混凝土梁施加相同荷载等级在不同损伤程度情况下混凝土梁从完整到破坏校验系数的变化规律,建立了校验系数与损伤程度、梁的跨度之间的数学模型关系式,实现了简支混凝土梁无损快速检测。

Using ANSYS finite element calculation, study the intact and different damaged extent of the concrete beam about their variation of calibration coefficient and frequency. Imposed by the same load of concrete beams with different damage levels,establish the formula about calibration factor, damage degree and the span of beam. Achieved simply supported concrete beam nondestructive rapid test.
