反应谱衰减系数变化对高土石坝地震响应的影响
Impact of varying attenuation coefficient of response spectra on dynamic analysis of high earth-rock dams
摘要
Abstract
The declining attenuation coefficients of the standard response spectrum indexγ is analyzed using the three-dimensional finite element method. The impact of indexγ on high earth-rock dams is analyzed based on the results proposed by Abrahamson and Silva (2007) whose research is funded by the American project“Next Generation Attenuation” (NGA). The suitable value for the indexγ is then discussed. The results show that the declining attenuation coefficientγ of the standard response spectrum taking 0.7 is more suitable than 0.9 for the earth-rock dam which is higher than 200 m.关键词
