Abstract:

Structures made from steel are emerging worldwide nowadays due to its high strength, high weld-ability, high weight and high weight to strength ratio. That’s the reason its usage are stretching into the bridges section. Constructors make use of several codes of practice to maintain economy, quality and safety the best. Many countries of Asia use another country’s design codes along with their own design to aim best quality, safety and economy. It is very essential to compare the codal provisions of Indian standards and European standards in the design of railway bridges made of steel. This will enable us to know that whether India or Europe standards are economical, better quality and safer than compared to another. Construction procedures of both countries in design of web, moment check, shear capacity, end stiffener, intermediate stiffeners are shown. By varying the Steel grade, Aspect Ratio (A.R), d/tw (web slenderness ratio) total steel (in tonnes) used in girder is taken. Also the variation of steel grades, A.R, d/tw along with steel weight and deflection are shown for deriving better results.

Keywords:

  Steel railway bridge, design, comparison, web slenderness ratio, deflection, aspect ratio, weight of steel.
