摘要
本文以统计资料为依据,采用蒙特卡罗(Monte Carlo)法模拟铁路钢桁梁桥典型压杆的初弯曲。在此基础上,提出以β分布来描述初弯曲的概率分布,并对初弯曲的设计取值提出建议。
The initial curvature or crookedness of a typical column from railway steel truss bridges is simulated by the Monte Carlo method based on statistical data. A β-distr ibution is proposed to describe the initial curvature. Design values with different assurance rates are estimated for the analysis of column strength.
