A Comparison Of Common Structural Materials, Molly Green

Williams Honors College, Honors Research Projects

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 …

Analysis Of Modern Barn Design, Gunther Soehnlen

Williams Honors College, Honors Research Projects

The agriculture industry is always changing. Barn structures are one of the most important aspects of the agriculture industry. As the agriculture industry changes, so does the design and construction of barns. There are many types of barns, but over the last 300 years four of the most prevalent types have been the Bank Barn, Open Span Truss Barn, Hoop Barn, and Transverse Frame Barn. The Bank Barn and Transverse Frame Barn have been popularly built for over 200 years. The Hoop Barn and the Open Span Truss Barn have been recently introduced to the industry, becoming popular within the …

Analysis Of Standardized Concrete Mixes, Riley Graybeal

Williams Honors College, Honors Research Projects

Concrete is one of the most common materials used in construction. It is mass produced throughout the country, with numerous different designs for concrete mixes. A common practice among concrete manufacturers is to use a standardized concrete mix design. These standardized mix designs are pre-tested and are not usually altered frequently. The hypothesis of this research project is that manufacturers do not constantly investigate new ways to save on their mixes, and simply use the same standardized mix designs.

In this research, investigations into what alterations may reduce the cost of standardized mixes began with a baseline mix design provided …
