英文摘要：

The status quo of and existing problems in research on multiple support excitations both at home and abroad were presented,including the vibration model for the long-span transmission tower,input of earthquake,and anti-seismic analysis.The anti-seismic calculation methods for the long-span transmission tower were discussed in detail.
