Transmission Tower Collapse Analysis With Wind Load Based On Ls-Dyna
CIVIL, STRUCTURAL AND ENVIRONMENTAL ENGINEERING, PTS 1-4(2014)
摘要
Large span transmission tower is the lifeline of electricity transmission, Its collapse destroyed will causes adverse to the social and economic effects, The mechanism of the power transmission tower collapsed caused people's attention. The analysis is based on LS-DYNA program, explicit beam161 beam element is adopted to establish the finite element model for transmission towers, Analyses the collapse process of transmission tower and its failure mode with downburst load.
