钢筋混凝土单跨叠层转换结构的静力分析与比较

Static Analysis and Comparison of Reinforced Concrete Single Laminated Transfer Structure

文章结合上海裕年国际商务大厦工程,对钢筋混凝土单跨转换大梁、叠层空腹桁架、叠层斜杆桁架和叠层K形桁架等结构的内力进行了分析和比较。分析表明,叠层斜杆桁架具有受力合理和传力途径清晰的特点,可作为该工程转换桁架的优先方案。同时,介绍了预应力叠层桁架的设计原则。

Combined with Shanghai Yunian International Commercial Affairs Building,the internal forces of reinforced concrete single transfer structure are analysized and compared by finite element,which including deep beam,laminated vierendeel truss,laminated level strut truss and laminated k type truss.It shows that laminated level strut truss has reasonable bearing forces and clear forces transmission way,which can been used as transfer member of this engineering.Besides,the design principle of prestressed laminate...
