摘要:
为解决拱桥吊杆损伤的精确识别难题,建立了一种下承式系杆拱桥简化力学模型,并通过力法推导得到 了下承式系杆拱桥吊杆应变影响线解析式,据此提出了一种基于下承式系杆拱桥吊杆准静态应变影响线指标的损 伤识别方法。 借助有限元法验证了该方法对于常规吊杆数目拱桥的适用性,并利用有限元模型算例研究了测试噪 声、损伤位置、损伤程度、损伤类别对损伤评估结果的影响,提出了科学的车辆加载实施方案。 研究结果表明:在 10%的测试噪声内,准静态应变影响线差值曲率法能精准定位拱桥吊杆的局部损伤位置,并可定量评估其损伤程 度,在系梁、风撑、拱肋等其他结构损伤时,该方法仍具有良好的识别效果。
Abstract:
In order to solve the problem of accurate identification of arch bridge boom damage, in this study a simplified mechanical model of an under-bearing tied arch bridge was established and the analytic formula of boom strain influence line of under-bearing tied arch bridge was obtained by force method derivation. Based on that, the damage identification method boom was proposed based on quasi-static strain influence line index of under-bearing tied arch bridge. Then the applicability of the method for conventional boom number arch bridge was verified with the help of finite element method. And the influence of test noise, damage location, damage degree, and damage category on the damage assessment results was studied by using finite element model calculations. A scientific implementation plan for vehicle loading was proposed. The results showed that within 10% test noise, the quasi-static strain-influence line difference curvature method could accurately locate the local damage location of arch bridge booms and quantitatively assess their damage degree. The method still had a good recognition effect when other structures, such as tie beams, wind braces, and arch ribs, were damaged.
