| 摘 要： | 合肥南站为特大型交通枢纽,主站房结构体系复杂,下部为混凝土框架结构,屋面为钢桁架结构。屋面纵向长度392m,大于300m的限值,为大跨度超长空间结构。通过设定合理的性能化目标,综合利用弹(塑)性时程等补充分析方法,进行了一系列复杂结构计算。设计采用了有针对性的抗震加强措施,使结构具有良好的抗震性能与延性,并顺利通过抗震设防专项审查。

| Abstract: | Hefei South Railway Station is a large-scale traffic hub,its main station building has complex structural system.The lower part is concrete framed structure,and the roof is steel truss structure.The longitudinal length of the roof is 392m which is beyond the limits of 300m in the code,so it is a large span and super-long space structure.It carried on a series of complex structure calculation by setting reasonable performance-based targets and using elastic(plastic) of the time history analysis methods synth... |
