| 摘 要： | 弦支穹顶结构由于拉索的存在，其施工阶段的力学性能与其使用阶段不尽相同，其受力状态可能更为不利。通过系统研究弦支穹顶结构实际工程的施工工艺，提出包括施工顺序、预应力张拉施加方式、临时支撑系统和预应力张拉方式等4个关键施工参数，研究了弦支穹项结构张拉环索受力机理，并根据此张拉机理和所提关键施工参数建立了有限元分析的时变模型，编制了相应的计算程序。算例分析表明，应用该计算模型和方法，可以对弦支穹顶结构的施工过程进行精确控制，具有较强的适用性。

| Abstract: | Mechanical behavior of Suspen-domes during construction is different with that in service and even more adverse because of cables introduced in the structures. By studying the actual suspen-dome projects, the key construction parameters for them were extracted and tensioning mechanism of hoop cables was studied. Then according to the tensioning mechanism and the key construction parameters, a numerical model and an algorithm for the whole process of tensioning were proposed. Moreover, a case study was addressed to approve the effectiveness. |
