【摘要】 对两个索膜工程的设计与施工过程进行了论述,并对两工程在施工过程及预应力的施加方法上的差别进行了横向比较:对于帐篷膜结构而言,设计对结构最终成功与否所起的作用更大,在该结构的设计中膜与柱相连节点的顶圈与环销相分离的做法是创新之处;对于活动铰支座形式的膜结构,施工所起的作用更大,施工方法是否正确、预应力施加与调整,对结构的最终成型有至关重要的影响。更多还原

【Abstract】 Design and installation of two cable-membrane structures are described. Especially, the difference in application of prestress and the construction process between them are compared. For the conical tent structure, design contributes more to the final success of this structure. Application of prestress and the construction process, however, are more important to the saddle cable-membrane structure.更多还原
