In this research work, a crack diagnosis method for beam-column structures is proposed considering axial load effects through experimental data. The proposed method is employed for the detection of damage locations including single and multiple damage scenarios considering four cases of simply supported beam-column. The results show that the locations of single and multiple damage scenarios can be well recognized in low axial loads considering random noise effect. However, in the vicinity of the critical load, healthy and damaged static data are uncommon. On the other hand, increasing the axial load, especially when it reaches to the critical load, has a negative effect on the static responses that is precisely considered by the proposed damaged index.

在这项研究工作中，通过实验数据提出了一种考虑轴向载荷影响的梁柱结构裂纹诊断方法。考虑到简支梁柱的四种情况，所提出的方法用于检测损坏位置，包括单个和多个损坏场景。结果表明，在考虑随机噪声效应的低轴向载荷下，可以很好地识别单个和多个损伤场景的位置。然而，在临界负载附近，健康和损坏的静态数据并不常见。另一方面，增加轴向载荷，特别是当它达到临界载荷时，会对静态响应产生负面影响，这正是所提出的损坏指数所精确考虑的。
