摘要
为开展换流站中电力输送系统关键设施主控楼的抗震性能研究,文中采用PKPM软件建立有限元模型,在8度地震作用下进行弹性时程分析。结果表明结构X、Y向层间位移角均超过GB/T 50011—2010《建筑抗震设计标准》规定的1/550限值,其中Y向超限更为明显,反映出该方向侧向刚度不足。通过增大柱截面、增设剪力墙等措施进行优化设计后,层间位移角被有效控制在规范范围1/550以内,整体抗震性能显著提升。研究成果可为换流站主控楼及类似工程的抗震设计与优化提供参考。
To investigate the seismic performance of the main control building of key facilities in a converter station power transmission system,a finite element model was established using PKPM software,and elastic time-history analysis was performed under an 8-degree seismic intensity.The results indicate that the inter-story drift angles in both the X and Y directions exceed the 1/550 limit specified in the Code for Seismic Design of Buildings,with the Y-direction exhibiting more pronounced exceedance,reflecting insufficient lateral stiffness in that direction.After optimization measures such as increasing column cross-sections and adding shear walls,the inter-story drift angles were effectively controlled within the 1/550 limit,and the overall seismic performance was significantly improved.These findings provide valuable reference for the seismic design and optimization of converter station main control buildings and similar structures.
