摘要
利用高效的随机振动虚拟激励法求解地震作用,结果表明:随着跨数的增加,纵向地震作用和频率逐渐趋向真解;同时,根据纵向地震作用,合理设置固定支座和墩的截面尺寸。
By using efficient random vibration pseudo-excitation method to solve the action of earthquake,and the result showed that as the number of span increases,the vertical earthquake effect and frequency gradually tend to the real solution,at the same time,according to the vertical earthquake effect,it has set reasonable fastening supports and the cross-section size of piers.
