中文摘要：
研究索穹顶与单层网壳组合的新型空间结构的受力性能.设计肋环型索穹顶与肋环双斜杆型单层网壳组合的结构,对其进行下部索穹顶预应力张拉试验以及结构在全跨和半跨荷载下的静力性能试验.根据试验结果对试验的计算模型进行修正,并将结构在全跨和半跨荷载下的试验实测数据与理论分析结果进行比较.结果表明,实测数据与理论分析之间差异较小,模型设计和试验方法合理,理论分析方法正确.修正的计算模型能准确反映结构的力学性能.
英文摘要：
Mechanical performance of a new spatial composite structure combined of cable dome and singlelayer lattice shell was studied. A composite structure combined of Geiger cable dome and rib-double-diagonal-patterned single-layer lattice shell was designed. Experiments on prestress tension of cable dome, static behavior of the composite structure under whole-span and half-span load were carried out. According to the experimental results, the computation model of the experimental structure was modified. The compari- son between the experimental and theoretical data show little difference. It indicates that the model design and experimental method are reasonable, and theoretical analysis method is correct. The modified computation model can reflect the static behavior of the composite structure correctly.
