摘要
对新版《中国公路钢桥规范(征求意见稿)》和国外钢桥规范的受压加劲板稳定承载力计算方法进行比较,以实例说明几种规范的整体稳定系数和局部稳定系数的差异.研究结果显示:中国公路钢桥规范的整体稳定四条柱子曲线与欧洲规范a、b、c、d曲线相接近,局部稳定系数取值小于其它规范对承载力的折减,计算结果相对保守.
This paper draws a comparison between the new edition of Chinese Highway Steel Bridge Design Specification （draft for soliciting opinions） and that of different countries, and consequently, illustrated the differences of integral stability coefficient and local stability coefficient with several actual projects. According to the research, four column curves of overall stability in Chinese Highway Steel Bridge Design Specification are close to a curve, b curve, c curve and d curve in European Specification, the value of local stability coefficient is lower than reduction factor of capability in other specification, and furthermore, the calculation results are relatively conservative.
