摘　　要：本文使用了结构可靠度的知识,通过工程结构软件ANSYS的可靠度分析模块对回盘式钢箱型梁的人行天桥的主跨在跨中部位在焊接残余应力的影响下满载的条件下进行了可靠性鉴定分析。鉴定结果表明人行天桥满足可靠性要求及基于ANSYS的蒙特卡罗算法的全概率可靠度验算可以很好地评估结构的可靠性。In this paper,the use of the structural reliability of knowledge through projects ANSYS structural reliability analysis software modules to the steel box beam walkway across the main span of the site under the influence of residuat stress load carried out under the conditions of reliability of identification. Identification results show that the walkway, the Monte Carlo Simulation ANSYS all probability algorithm can be very good reliability checking the reliability of the assessment of the structure.
