| dc.description.abstract | Ethiopia is one of the mountainous countries in Africa. This topographic condition such as rough terrain, deep gorges of the country; river crossings and other factors aggravate the difficultness of construction of roads in the country without constructing crossways which include culvert and bridges. Thus, Bridges are vital structures required during roads construction. The type of structure in design standard is selected on the basis of openings span in which culverts span 1 to 6m, slab bridge span 6 to 15, and up to 18m with provision, while T-Girder bridge span 10 to 20m, where sometimes span up to 24m. The site visit during this study also reveals that slab bridges up to 12m and T-Girder bridges as low as 9m span have been recorded. This lead to the requirement of the standard to narrow the span gap at the boundary for selecting slab or T-Girder in the range of 10 to 15m spans. In line with this the thesis of this study focused on developing computer program for analysis and design of slab and T-Girder bridges, in due cause solving the design problem of economical spans for slab and T-Girder bridges. A comparative study on the basis of cost of materials is conducted to select and identify the economical span range of slab and T-Girder bridges. The developed program is illustrated using particular example of both slab and T-Girder bridges. The study has come with solution based on the prevailing rates of construction cost to be adopted for design Engineer’s use. | en_US |
