摘要
结合工程实例研究地铁上盖全框支剪力墙结构体系受力特点、抗震性能及可靠性,采用多个常用有限元计算软件进行结构弹性和弹塑性分析,并对关键的厚板转换结构进行专项有限元分析。结果表明,该结构体系能够通过转换构件有效传力,在不同地震水准作用下能够满足抗震性能水准要求,避免上盖塔楼的竖向构件落地,能够最大化利用盖板并提高上盖物业开发强度,更高效地利用城市中心的土地资源,为今后类似地铁上盖项目开发提供一定参考及借鉴。
In this study,the force characteristics,seismic performance and reliability of fully frame-supported shear wall structural system of metro superstructure were analyzed in combination with engineering examples.The elastic analysis and elastoplastic analysis of the structure were carried out by multiple commonly used finite element calculation software,and the specialized finite element analysis of the key thick-plate transfer structure was performed.The analysis shows that the structural system can transmit force through the conversion of components effectively,and meet the requirements of seismic performance under different earthquake levels.It can avoid the vertical components of the upper tower falling to the ground,maximize the use of the cover plate,improve the development degree of the cover property,and more efficiently utilize the land resources in the urban center.This study can provide some reference and inspiration for the development of similar subway upper cover projects in the future.
