Influence of diagonal cracks on negative moment flexural anchorage performance in reinforced concrete bridge girders

Creator:

Goodall, Joshua K.

Abstract:

Large numbers of vintage reinforced concrete deck-girder bridges remain in the national bridge inventory. Many of these exhibit diagonal cracking and other distress. Due to the design practices of the time, it is common to observe cracks at locations where flexural reinforcing steel is terminated along the span. The presence...

Development and evaluation of oriented strandboard bonded with soy-based formaldehyde-free adhesives

Creator:

Schwarzkopf, Matthew John

Abstract:

Synthetic adhesives like phenol formaldehyde (PF) and isocyanates dominate the wood based structural panel market. The raw materials that makeup these adhesives are based on petroleum and natural gas. The sustainability and the continued success of the wood based structural panel industry will benefit from the development of alternative adhesives...

Semi-volatile fluorinated organic compounds in Asian and Pacific Northwestern U.S. air masses

Creator:

Piekarz, Arkadiusz M.

Abstract:

Current studies suggest that perfluorinated organic compounds, such as fluorotelomer alcohols (FtOHs) in the troposphere, may be precursors of perfluorocarboxylic acids and perfluorosulfonates in remote regions. Fluorinated organic compounds were investigated in archived extracts collected from remote locations in Okinawa, Japan (HSO) and Mount Bachelor, Oregon (MBO) during the springs...
