[摘要]為研究人為誤差影響下的結(jié)構(gòu)可靠性,應(yīng)用污染分布模型來(lái)確定隨機(jī)誤差和人為誤差作用下的結(jié)構(gòu)參數(shù)變量的均值與方差。并在此定量分析的基礎(chǔ)上合理確定人為誤差對(duì)結(jié)構(gòu)可靠度的影響。研究結(jié)果表明:目前的可靠度分析研究中沒(méi)有考慮施工過(guò)程中人為誤差這一不確定性因素,其研究結(jié)果與實(shí)際情況存在偏差。在不確定性因素的影響下,為保證建筑結(jié)構(gòu)可靠度達(dá)到既定的安全水平,必須合理準(zhǔn)確地確定人為誤差影響下的結(jié)構(gòu)可靠度。

Abstract: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.
Keywords:human error; structural reliability; failure probability; contaminated distribution
