Railway bridge

If you design a railway bridge (condition A) with span 100 m or more (condition B), then design your bridge as a steel bridge (action D). 

CCP has many advantages over the conventional mode of transportation continuous uninterrupted transport no dependence on availability of roads, railways, bridges, and so forth least manpower requirement possibility of crossing any odd areas like seas, oceans, rivers, mountains, and underground space ensured safety and purity of the product minimal loss of quality or quantity comparatively lower cost of transport per unit of the product conveyed fastest mode of transport and relatively smaller hazard. 

Measurements were carried out to verify the non-linear calculation methods of longitudinal forces in long, high railway bridges. The practical and theoretical background of the tests is described. Specially chosen methods of loading and measuring the reaction of the structure are appointed to the separate static and dynamic problems. 

In this paper a research project entitled as "Rehabilitation of Old Railway Bridges which was financially supported by NATO Science for Stability with the code name TU-850 BRIDGES Programme will be briefly presented. Following this, data collection, acquisition and evaluation procedures planned to use for this project will be summarized. Finally, the equipments procured for this project with their properly selected specification wiU be presented. 

Classification of the railway bridges have been done. A computer program was developed for this purpose. Then, seven bridges have been selected for the first bridge-testing activities. 

The centrifuge test results and subsequent FE analyses show that it is possible to investigate the soil behaviour during liquefaction and make reasonable predictions of the settlements suffered by the foundations of bridges. In the next section of the artiele, the Bachau-Vondh railway bridges will be considered in the immediate aftermath of the Bhuj earthquake of 2001. It will be argued that the super-structure stifihess has an important role to play in how the soil-structure system behaves, once the foundations suffer liquefaction. 

Train load according to European Standard EN 1991-2 Eurocode 1, Section 6, Rail traffic actions and other actions specifically for railway bridges and approaches. Section 6 of Eurocode EN1991-2 describes a 4-point load each 250 kN center-to-center 1.6 m. 0.8 m from each point load to total live load of 80 kN/m per track. Effective width is 3 m on 0.7 m depth (base ballast bed). This equals a maximum traffic load of 52kN/m. Due to spreading of the load in the...
