Simplified aseismic calculation model for transmission tower-line system considering pile-soil dynamic interaction
摘要
Abstract
The simplified aseismic calculation model for transmission tower-line system considering pile-soil-dynamic interaction is given. A simplified aseismic calculation model for pile-soil-transmission tower-line system is set up using the additional mass method and lumped mass model. Based on a transmission tower, the seismic response of the simplified model for pile-soil-transmission tower-line system is calculated and compared with the complete model suggested in Reference [5] under three different site conditions. It can be concluded that the results of the simplified model is in good agreement with of the complete model. Examples show that the method saves calculation time and promotes calculation efficiency greatly. It is also shown that lines have a significant effect on the dynamic response of the system on soft sites and medium sites. Results of the study can be applied as a reference for engineering design.关键词
