The Fundamental Study on the Damage Deteciton of Steel Moment Frames with Beam-hinge Collapse Mechanism
초록
The artificial neural network (ANN) based damage detection method is prposed for the steel moment frames with beam-hinge collapse mechanism. The natural frequencies, modeshapes, flexural moment of columns are employed as the values for the input layer while the raios of rotational stiffness of connections before and after damage are employed as the values for the output layer. The 5-story steel moment frame with beam-hinge collapse mechanism is used as the example structure.
