The state of Ohio is in a region that commonly experiences drastic changes in weather. States with similar climates are susceptible to pavement cracking and failures due to the frequent or extreme freeze-thaw cycles. Freeze-thaw cycles, paired with de-icing chemicals that are frequently placed on roadways during the winter months will most likely lead to pavement cracks and failure. Ohio Department of Transportation (ODOT) routinely repairs and replaces sections of concrete roadways and bridge decks. Therefore, ODOT is seeking durable, cost-effective materials to repair smaller pavement failures.

The purpose of this study is to determine which high performance repair materials …

The Behavior Of Simply Supported Plates Under Extreme Shear Loading, Mhd Ammar Hafez

ETD Archive

Steel plates are planar structural elements with one dimension significantly smaller than the others. These elements may fail due to either material yielding or buckling. Buckling is a sudden failure mode, which is not desirable in structural engineering applications. Buckling is called an “elastic buckling” when it happens before material yielding, and is termed as “plastic buckling” if it happens after material yielding. The focus of this thesis is on shear plates, which are plates that are primarily subjected to shear loads. Several studies were conducted to increase the elastic buckling capacity of plates by adding stiffeners to plates. However, …

Interlocking Concrete Masonry Unit Geometry Design, Raquel Avila, Nick Jensen

Civil, Environmental and Sustainable Engineering Senior Theses

Earthquakes in Haiti and Nepal left many people devastated. Millions of people were initially displaced and forced to reside in displacement camps. Developing countries like these need a form of economical construction. Our design and manufacturing process for interlocking CMU (concrete masonry unit) blocks can help build low-cost homes quickly and efficiently. Wall construction costs are reduced because skilled masons are not needed to build the wall. Instead, unskilled homeowners and laborers can stack the interlocking blocks, which serve as forms for the subsequent placement of reinforcement and grout within some of the CMU block voids. Using a steel mold, …
