| 摘 要： | 通过对一个带钢桁架转换层框架剪力墙高层结构工程实例的建模和分析,采用有限元理论计算方法对此类带钢桁架转换层结构的动力特性、结构转换层局部的比较和选型、弹性动力时程分析和反应谱分析的具体应用方面进行了一定的研究.结果表明,在大荷载条件下应用桁架转换结构是完全可行的,而且在很多时候应用桁架转换结构比梁式或其他形式的转换结构更为合理.另外,就桁架转换的具体形式而言,带竖杆的斜杆桁架转换形式的内力分布、变形指标和配筋结果更为合理,应作为首选的结构方案.

| Abstract: | Based on the finite element modeling and analysis of an engineering case,which is a frame-shear wall high-rise structure with steel truss transition layers,some preliminary research was made on the dynamic characteristics of such structures,the partial comparison and type selection of transition layer as well as the specific application of elastic dynamic time-history and response spectrum analysis.The results show that truss transfer structure is totally feasible under the condition of heavy load,and for m... |
