| 摘 要： | 考虑地震动的空间变化效应,对自锚式斜拉-悬吊协作体系桥进行了随机地震反应分析。研究了P波、SH波和SV波作用下该协作体系内力和位移峰值响应的特点,对比分析了均匀一致地面动和多点非一致地面运动对其地震反应的影响,计算中由于虚拟激励法的引入,计算效率获得极大的提高。结果表明行波效应和部分相干效应对该类超大跨径桥梁地震反应有相当大的影响。 |

| Abstract: | Random seismic response analysis of self-anchored cable-stayed suspension cooperative system bridge is implemented considering seismic spatial effects. The peak response of internal force and displacement of the cooperative system is investigated under P wave,SH wave and SV wave, and the seismic response subjected to uniform excitations and multi-support non-uniform excitations are compared and analyzed. The calculating efficiency is improved greatly owing to adopting the pseudo excitation method. The results reveal that tile traveling effect and the coherence effect greatly influence the seismic responses of this type of long span bridges. |
| Keywords: | self-anchored cable-stayed-suspension bridge random spatial effect coherence |
