Field Observation Of Installation And Performance Of Repair Materials, Larisa Diana Susinskas

ETD Archive

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 …

Specification Recommendation For Use Of High Performance Repair Material, Jennifer Woods

ETD Archive

The State of Ohio and the Ohio Department of Transportation (ODOT) have sought out ways to extend the life of the repair materials used by their construction crews, specifically, using high performance repair materials for the purposes of patching worn down or cracked sections of highways and bridge decks. Ohio is known for its frequent changes in weather, with freeze-thaw cycles occurring multiple times throughout the year. These cycles affect the lifespan of the repair material and create more maintenance for the DOT. Products that combat this problem were chosen, installed and examined over a year period to determine which …

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, …
