Research on the Influence of Boundary Conditions on the Seismic Performance of Hoisting Cable Tray
The lateral stiffness of the hoisting cable rack in the communication room is relatively weak.When subjected to earthquakes,the cable rack will produce significant relative displacement,causing damage to its own structure and load-bearing cables,which is the weak point of the seismic resistance of the information and communication network.The force analysis of the lifting cable rack system was conducted,and the overall lateral stiffness of the system was obtained.Using Simulink to model the system and conduct elastic-plastic time history analysis,obtain the system response trend under various boundary conditions,and provide reinforcement suggestions under different installation conditions.A seismic test on the hoisting cable rack is conducted,and the test results verified the effectiveness and accuracy of the model.It can objectively reflect the inherent laws between boundary conditions and the seismic resistance of the hoisting cable rack,and provide reference for engineering installation and the formulation of relevant seismic codes.
