UBB在太原南站综合交通枢纽工程中的应用

Application of UBB in Taiyuan South Railway Station

对太原南站综合交通枢纽工程采用UBB进行了消能减震设计,介绍了UBB的布置情况,采用PKPM等软件分析了UBB对多遇地震下结构层间位移角和节点受力的影响,采用ABAQUS软件对采用UBB后的结构进行了罕遇地震作用下的动力时程分析。分析结果表明UBB对控制结构层间位移角、增强结构抗扭能力、改善节点受力有明显作用,采用了UBB的结构在罕遇地震下具有较好抗震性能和耗能能力。

UBB was used as an energy dissipation device in Taiyuan south railway station. The arrangement of UBB was introduced,its effects to the storey drift angle and the connection force under frequent earthquake was investigated using PKPM,and the performance of the structure equipped with UBB under rare earthquakes was analyzed using a finite element program called ABAQUS. The results suggest that UBB has significant effects to control the interstory drift and improve the connection,and the structure equipped with UBB has satisfactory performances under the rare earthquakes.
