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 to design the energy dissipating and damping system for the comprehensive transportation hub project of Taiyuan South Railway Station. The layout of UBB was introduced. The influence of UBB on the displacement angle and the stress of joints under the earthquake was analyzed by PKPM software. ABAQUS software analyzes the dynamic time history of UBB structure under rare earthquakes. The analysis results show that UBB has a significant effect on controlling the displacement angle between layers, increasing the torsional resistance of the structure and improving the stress of the joints. The UBB structure has better seismic performance and energy dissipation capability under rare earthquakes.
