Sustainability And Environmentally Friendly Methods To Travel Over Waterways, Kendall Kubus
Sustainability And Environmentally Friendly Methods To Travel Over Waterways, Kendall Kubus
Williams Honors College, Honors Research Projects
Throughout daily traveling, the main structures used are bridges and tunnels. Bridges are used as overpasses over valleys, canyons, and areas that require a large amount of dirt fill to bring the roadway up to the proper grade. Tunnels are underpasses through mountains, under city limits and waterways. The benefits of building a bridge structure is little preparation goes into earth-work and the transportation of aggregate materials. There is some time spent testing surrounding soil to determine the process that will need to occur for foundation preparations in bridge columns. Options for foundation include different types of drilled shafts, caissons, …

This report will compare structural steel, concrete, and lumber through the lenses of mechanical properties, design process, cost, and environmental impact. Steel is a versatile, strong, and lightweight material that comes at a premium price – both financially and environmentally. It is the most expensive material of the three included in this report. This is largely due to its complex manufacturing process that is also responsible for a significant amount of the world’s carbon dioxide emissions. Concrete is significantly less expensive than steel, but the carbon dioxide emissions from manufacturing are approximately equal. Concrete also only performs well in compression …
Comparative Analysis Of Bridge Abutment Types, David Fell
Comparative Analysis Of Bridge Abutment Types, David Fell
Williams Honors College, Honors Research Projects
This project was developed to serve as a brief overview of design practices and considerations in the selection of highway bridge abutment types. This involved a review of literature in the form of reviewing national design guides and department of transportation (DOT) requirements from both US DOTs and international DOTs. The abutment types covered in this research included conventional reinforced concrete abutments with bearings, integral abutments, and semi-integral abutments. This research focused solely on highway bridge abutments, particularly on Ohio Department of Transportation design requirements due to their extensive use of semi-integral abutments. Superstructure elements and geometric requirements are primary …
