A Comparison Of Common Structural Materials, Molly Green
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 …

Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
The Summer Undergraduate Research Fellowship (SURF) Symposium
Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …

Most of the available shear models for reinforced concrete rely on empirical formulations. In this study, a rational shear stress function is used to define the shear stress–strain envelope for reinforced concrete. Cyclic rules are proposed to define the loading, unloading and reloading relationships for reinforced concrete under shear stress reversals. A normal stress function describing the cyclic relationship of concrete under axial stress is also introduced. The proposed functions are verified using experimental data of reinforced concrete panels tested under monotonic and cyclic loading. Subsequently, the normal and shear stress functions along with their cyclic rules are integrated in …
