Methods for strengthening flexural steel details in reinforced concrete bridge girders using a near-surface mounted retrofitting technique

Creator:: Amneus, Deanna
Abstract:: Many older reinforced concrete deck girder (RCDG) bridges contain straight bar terminations of flexural reinforcement. Common bridge design practice of the 1950s did not consider the additional demands on the terminated bars from shear and flexure. Moreover, more stringent code specifications and heavier permit trucks contribute to the insufficient ratings...

Behavior and analysis of pile caps with poor anchorage details

Creator:: Sorentino, Anthony William
Abstract:: Pile caps are structural elements used to transmit loads from structural columns into pile groups. A pile cap is generally constructed of reinforced concrete and contains only minimal flexural reinforcing steel. Using modern design methods, the anchorage of the flexural steel may limit the design capacity of existing pile caps....

Design and environmental performance of near-surface mounted carbon fiber reinforced polymer strips for shear strengthening reinforced concrete bridge girders

Creator:: Goebel, Jacob Hans
Abstract:: During the interstate expansion of the 1950s, many conventionally reinforced concrete deck girder bridges were built throughout the country. These now vintage bridges commonly exhibit diagonal cracking and rate inadequately for shear, thus they are candidates for shear strengthening to extend their useful life. Near-surface mounted (NSM) retrofitting is a...

Carbonation of Mid-Twentieth Century Reinforced Concrete Bridges in Oregon

Creator:: Folkestad, Jill Louise
Abstract:: Carbonation of Carbon is of concern for reinforced concrete bridges. While long-term environmental deterioration of structures is unavoidable, protective design allows a structure to fulfill its service life without any significant serviceability or strength loss due to deterioration. Understanding the process of concrete carbonation and the effect it has on...

Design, analysis and evaluation of bridge superstructures for live loads

Creator:: Turan, O. Tugrul
Abstract:: Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...

Investigation, analysis and design of an experiment to test ponding loads on flexible roof systems

Creator:: Stark, Duncan
Abstract:: While damages due to ponding are common and expensive, provisions for design and construction of flat roof systems lack guidance regarding these loads. The goal of this research is to present methods of designing or building flat roofs that are less vulnerable to this condition. An investigation of the literature,...

Applying climate change information to hydraulic and hydrologic transportation infrastructure

Creator:: Al Naabi, Rawan Y.
Abstract:: Scour is the main cause of bridge failures in the United States. Bridge failures raise a hazard to the safety of the traveling public as well as the massive economic consequences due to the high cost of constructing a new or a replacement bridge. The Oregon Department of Transportation (ODOT)...

Cross-Laminated Timber-Concrete Composite Floor Systems for Tall Building Design

Creator:: Morrell, Ian
Abstract:: With growing interest in mass timber, especially mass timber panels (MTP), there has been a need to better understand their structural properties. One of the most versatile uses for MTP are as floor systems. Under new code provisions, these floors can be utilized in new and taller building types, but...

Experimental and Analytical Studies of Large-Scale Pile Caps

Creator:: Al-Sakin, Yasmeen
Abstract:: Pile caps are structural elements used to transfer loads from columns to a group of piles, which transfer them to stronger soil layers. Pile cap with horizontal distance between the column and piles less than twice its effective depth is categorized as "deep," where significant nonlinear strain distribution occurs through...

Dual Purpose Utilization of Titanium Alloy Bars for Impressed Current Cathodic Protection and Near Surface Mounted Retrofit in Reinforced Concrete Beams

Creator:: Slawinski, Amanda K.
Abstract:: Many older reinforced concrete bridges and buildings in the United States are considered deficient due to past design codes that are not conservative, increased loading, and deterioration of structural components. Deterioration is most commonly caused by corrosion, which reduces the steel cross sectional area and damages the concrete cross section....
