摘要
为研究人为误差影响下的结构可靠性,应用污染分布模型来确定随机误差和人为误差作用下的结构参数变量的均值与方差。并在此定量分析的基础上合理确定人为误差对结构可靠度的影响。研究结果表明:目前的可靠度分析研究中没有考虑施工过程中人为误差这一不确定性因素,其研究结果与实际情况存在偏差。在不确定性因素的影响下,为保证建筑结构可靠度达到既定的安全水平,必须合理准确地确定人为误差影响下的结构可靠度。
In order to study the structural reliability with the effect of human error,the contaminated distribution model was employed to obtain the realistic mean value and standard variance of variable of structural parameters which coexisted with random error and human error.The influence degree of structural reliability with the effect of human error can be calculated based on the quantitative analysis.The results show that the current studies do not consider human error in construction for structural reliability.It is not comply with the real situation.The reliability index must be evaluated precisely to ensure the certain level of structural reliability due to uncertain factors.
