摘要：
With the increase of the span and height of modern engineering structures, the design complexity of the cable structure is constantly increasing, whose dynamic problem has become the key to structural design, performance monitoring and maintenance, and vibration control. Therefore, it is necessary to study and develop a new dynamic analysis theory for complex cable system with higher calculation accuracy and efficiency to meet the requirements of exact analysis of engineering structures. In view of this, a novel dynamic analysis method for shallow sagged cable system is proposed in this paper based on the dynamic stiffness method. Since the derivation process is given in analytical form, the calculation accuracy and efficiency are promoted greatly. The numerical cases are used to verify the accuracy of the proposed dynamic analysis method, meanwhile, the simulation results show that the proposed method can overcome the "root missing" phenomenon when solving the frequency equation by the existing analytical method. © 2020 Journal of Northwestern Polytechnical University.
