[摘要]合肥南站為特大型交通樞紐,主站房結(jié)構(gòu)體系復(fù)雜,下部為混凝土框架結(jié)構(gòu),屋面為鋼桁架結(jié)構(gòu)。屋面縱向長度392m,大于300m的限值,為大跨度超長空間結(jié)構(gòu)。通過設(shè)定合理的性能化目標(biāo),綜合利用彈(塑)性時程等補充分析方法,進行了一系列復(fù)雜結(jié)構(gòu)計算。設(shè)計采用了有針對性的抗震加強措施,使結(jié)構(gòu)具有良好的抗震性能與延性,并順利通過抗震設(shè)防專項審查。

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 synthetically. The targeted seismic strengthening measures were used in the design which make the structure have good seismic performance and ductility, and passed the special inspection of earthquake-proof.
Keywords:overlong spatial structure; wind-induced vibration analysis; performance-based seismic design; elasticity in the precautionary intensity earthquake; elastic-plastic analysis
