Transmission tower occupies an important position in the event of transmission of electricity. The failure of transmission tower would cause serious economic losses. As a damage identification parameter, variation ratio of curvature mode has a great ability to damage location. In the field of damage location identification on transmission tower, variation ratio of curvature mode achieved good results...
Based on wavelet packet energy and RBF neural network, the damage identification of principle material of a long span power transmission tower is presented in this paper. The dynamic response signal of displacement-time of the damage and undamaged tower subjected to seismic excitation is obtained. In addition, the wavelet packet energy curvature difference of pre-damage and post-damage states of tower...
Half-through arch bridge is an important traffic structure, so it is extremely valuable to study the damage location questions on the condition of suspender damage. Based on the finite element modal, the efficiency of the variation ratio of curvature is researched in this paper. As it turned out, variation ratio of curvature which is a modal parameter, could locate the initial damage position, as...
Method of support vector machine (SVM) as a new machine learning algorithm has shown its superiority of the ability of regression in the fields of damage identification. Through setting variation displacement of mode shape to the feature parameters of damage identification, the method of the damage identification of long-span cable-stayed bridge based on SVM is presented. The method of least square...
