Seismic Performance Analysis of Transmission Tower System Based on MATLAB Numerical Calculation
Transmission tower line system dynamic response and failure mechanism are very complex under seismic load, the dynamic response and cooperation mechanism of the upper structure, pile and soil of transmission tower line system under seismic load based on the MATLAB numerical calculation method in this paper, and the displacement, acceleration velocity and displacement of axial force distribution of different positions of transmission tower line system are calculated by building transmission tower line of the stiffness matrix, equivalent load node, system quality matrix, motion equation and the upper structure of whole pile of model and with the help of the solution of the MATLAB function. The numerical calculation results show that the soil-consider the upper structure of pile-coordination effects for displacement and acceleration amplification effect are obvious, but the truss of axial force amplification effect is relatively small. Meanwhile, the earthquake action soil pile-between the upper structure are strong dynamic interaction, which provides certain theoretical guidance for recognizing transmission tower line system dynamic response mechanism under earthquake and adopting efficient anti-seismic measures.
