【摘要】 本文结合湖南省建设厅课题“竖向桁架式高层建筑结构的研究”，介绍了用VC++和Fortran混合编程开发“竖向桁架式高层建筑结构时程分析系统”—NLA的若干技术。利用NLA对带斜杆的竖向桁架式钢筋混凝土高层建筑结构进行了抗震性能的研究，重点考察了不同斜杆布置方式对此种结构抗震性能的影响；对不同层数下此种类型的结构与纯框架结构的抗震性能作了比较。用大型有限元分析软件ANSYS分析了此种类型结构的节点，指出了它的应力分布规律，从构造上提出了建议。此外，还对此种结构的施工方法作了论述。更多还原

【Abstract】 The development of the Time-History Analysis System-NLA forhigh-rise building with braced frame with VC++-Fortran mixed languageis introduced in this thesis under the topic-"Study of the vertical hign-nsebraced frame building" belong to the Hunan construction bureau. Theaseismic behaviour of the high-rise building with bracings is studied byNLA. The influence to the aseismic behaviour of this kind of structurewith different bracing arrangement is studied in particular. Comparisonsof the aseismic behaviour between frame and braced frame in differentrises is performed. The joint in this kind of structure is analyzed byANSYS-a large-scale finite element analysis software and the stressdistribution regularity and the joint construction is pointed in this thesis.Additionally, the construct method of this kind of structure is alsomentioned.更多还原
