摘　　要：进行了几种涂层织物类建筑膜材的拉伸强度试验,基于现有的设计规程和统计资料,对主要的力学参数进行了统计分析,为提出准确的抗力分项系数提供了数据储备.总结了现行国内外膜结构技术规程对于膜结构设计的规定,介绍了我国规程中抗力分项系数的推导过程,最后采用'校准法'求得了相应的结构失效概率,发现两类荷载组合对应的安全系数都是安全的.Groups of tensile tests on architectural coated fabrics were carried out. Based on the current design specifications and experiment statistics, the main mechanical properties were analyzed to provide data for accurate partial coefficients. Then, the current design specifications for membrane structures were summarized and the safety factors in domestic specification were analyzed. Finally, the calibration method was adopted to determine the failure probability of membrane structures. The results have shown that the safety factors for the two load combinations are safe.
