Longitudinal Response of Power Transmission Tower-Cable System to Traveling Wave
Abstract eng: Based on the established model of power transmission tower-cable system, seismic response is analyzed with time history method. Seismic response to traveling wave is compared with uniform wave, the results indicate that: traveling wave excitation can increase, as well as decrease, the seismic response of power transmission tower-cable system which depends on both traveling wave velocity and ground motion characteristics; traveling wave excitations increase the cable’s axis force to a large extent, which will decrease gradually and approach to the case of uniform excitations as velocity increasing; traveling wave strongly magnified cable’s displacement response in longitudinal and vertical direction, especially the latter term under excitations of near-fault ground motions; traveling wave velocity has great affection on the seismic response of power transmission tower-cable system.
