1三跨对称刚架满足倍数定理的设计设三个等高单跨刚架跨度,线刚度如图1所示。显然,水平荷载作用下梁、柱线刚度满足倍数定理,倍数关系为1:n:1,有理由合并为三跨对称刚架如图2所示。图1等跨刚架荷载图图2简化图当框架采用相同混凝土级别,梁、柱采用矩形截面且跨度b均相等时,梁线 | | |  推荐 CAJ下载  PDF下载 | | | CAJViewer7.0阅读器支持所有CNKI文件格式，AdobeReader仅支持PDF格式 | | | | The Application of the Multiple Theorem in the Design Of Regular frame of High-rise Buildings | | | TAN Ruo-ming1;FANG Yong-han2(1.College of Continueing Education;Guizhou Uncversity Guiyang;Guizhou;550003;China;2.Light and Textile Design Lnstitute;Guiyang;Guizhou;550003;China) | | | This paper discusses how to use the multiple theorem of structural mechanics in multiple eheorem of structural mechanics in multilayer(or high-rise)three-span symmetrical and two-span nonsymmetrical frame inter-force analysis.When first pillar section size hb of multilayer or high-rise frame joist,at first to satisfy the multiple theorem and and then to use exact non-shearing-force distribute to analysis inter-force.It results in knowing more about non-shearing-force distribute by2/3,reducing computer deposit and making hand-dealing more convenient.
