摘　　要：本文为了论证单层网壳结构弹塑性稳定分析的理论,进行了单层网壳结构的弹塑性稳定试验研究.结果表明,网壳结构的失稳具有缺陷敏感性,并且部分杆件的塑性变形对其稳定性能及承载能力有着显著的影响.An experimental study on elastoplastic stability of single layer reticulated shells has been carried on in the laboratory to verify the analysis theory. It is proved that the stability of reticulated shells is quite sensitive to structural imperfections and the plastic deformation of the part members has significant influence on the structural stability and load capacity of the shells.
