淮北火车站结构设计
|
摘要
淮北火车站建筑总面积1.9万m~2,含站房、天桥和雨棚。结合工程概况,介绍了结构计算标准、荷载作用,并着重阐述了其计算分析和结构设计。采用MIDAS等有限元分析软件对结构各部分进行了建模计算分析。分析结果表明,结构布置合理,各项指标均满足规范要求;车站大跨度楼盖采用预应力混凝土梁,能解决大跨度梁梁高问题,且能满足结构强度、绕度、楼盖舒适度等各项指标要求;车站雨棚采用刚架+组合屋面结构,具有耐久、美观、抗风性能更好等诸多优点,是车站站台雨棚的良好选型。本工程的设计对同类型铁路车站和类似结构具有参考指导意义。
The total area of Huaibei Railway Station is 19 thousand square meters, including the main station building, flyovers and canopy. Combined with project overview, the structure calculation standards and load effects were introduced and focuses on its computational analysis and structural design. MIDAS and other finite element analysis software were adopted for the structure modeling. The analysis results show that the structural arrangement is reasonable and all indicators meet the regulatory requirements; the using of prestressed concrete beams for station large span floor, can solve the problem of large-span girder beam height, as well as meet the requirements of structural strength, deflection and floor comfort; rigid frame structure with composite slab is used for the station canopy, with the advantages of durable, aesthetic and better wind resistance, which is a good selection for the station platform canopy. The engineering design of this project has reference significance for the same type railway station and similar structures.
