| 摘 要： | 结合大跨度索承网壳结构自身形式的特点,提出了一种针对此种结构的新型施工方法———分层张拉成形法。在理论分析的基础上进行了模型试验,成功地验证了这种方法的可行性。讨论了试验实施中的节点设计及预应力张拉方法问题,为配合本次试验设计了一种新型节点,并通过试验验证了其可靠性。

| Abstract: | Based on the characters of prestressed cable supported lattice shell, a new construction method is bring forward in this paper. In this method the shell is constructed through tensioning by layers and the prestress is applied layer by layer also. An experiments is designed to verify the validity of the new method, besides the tension method and a new node form which is self-designed to cooperate the experiment are discussed in this paper. |
