摘要 提出了桥梁长期健康监测中基于恒载进行梁及桥梁损伤识别的方法。首先从正分析入手计算超静定梁仅在恒载作用下发生损伤的特征表现,通过分析不同监测参量及测点对损伤的敏感度,研究仅在恒载下监测参量选取及测点布置的特点;再从反分析出发通过改进的自适应遗传算法求解有约束的优化问题,研究仅在恒载作用下识别梁损伤的可行性,分析结果表明通过较少测点即可对梁的损伤进行识别,为基于恒载的损伤识别方法在实桥健康监测中的应用提供了理论指导。 We address damage detection based on dead loads in monitoring the health of beams and bridges. We discuss the damage characteristics of statically indeterminate beams under dead loads and analyze monitoring parameters and sensor placement in monitoring. We used an amended genetic algorithm to solve the optimization problem under constrained parameters. Damage in a beam was detected successfully based on dead loads with limited sensor allocations. We present a way to detect damage based on dead loads in bridge health monitoring.
