摘要 以一次二阶矩可靠性理论为基础,将可考虑基本变量概率分布类型的R-F法应用于含缺陷焊接结构的可靠性安全评定中。算例计算表明,该方法简单实用,计算精度较高,在工程焊接结构的可靠性安全评定方面有较大的实用价值。 In this paper the R F method based on the First order second moment reliability theory was introduced for the safety assessment of welded structure with cracks,which will consider the probabilistic distrbution type of basic variables.An example shows that this method is simple,useful and accurate.
