摘要
介绍了澳大利亚标准AS 5100.2:2017的铁路桥梁基准活载等级及其他等级活载图式,提出了桥梁在标准活载和评估车辆载荷作用下所受最大静态剪力和弯矩的计算方法,并推导了相关的计算公式;采用Visual Basic语言编写了校核计算程序,并对计算程序的正确性进行了验证。验证计算和运用实例表明,文章所述计算方法正确,程序计算精度满足实际需求,能够有效指导出口澳大利亚铁路货车设计。
This paper introduces the reference live load and other live loads of railway bridges based on Australian Standard AS 5100.2:2017,proposes the calculation methods and relevant calculation formulas of the maximum static shear force and bending moment of bridges under standard live load and estimated vehicle load.The correctness of the calculation is verified by verification calculation programming by Visual Basic language.The verification calculation and application examples show that the calculation method is correct and the calculation accuracy of the program meets the actual needs,which can effectively guide the design of freight cars exported to Australia.
