摘要

采用时程分析法系统地分析了多点输入下大跨越输电塔结构的地震响应,分析了在不同视波速下地震对大跨越输电塔位移、扭转效应、塔柱和腹杆最大压应力的影响。研究表明:多点输入下地震对结构扭转效应非常明显,对塔柱底部杆件内力影响较大,与一致输入下相比杆件进入塑性的数量较大。
Seismic response analysis is done by using time history analysis method in long crossing transmission tower under multiple support excitation.The impact of the earthquake under five apparent velocities on displacement,torsion and axial stresses in main legs and web members of the long crossing transmission tower was analyzed.The results show that the structure develops larger torsion under multiple support excitation,members on the bottom and plastic member of the long crossing transmission tower are greater under multiple support excitation than simple support excitation.
