Reducing sediment production from forest roads during wet-weather use

Creator:

Toman, Elizabeth Myers

Abstract:

Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...

Slotted-bolted friction damper as a seismic energy dissipator in a braced timber frame

Creator:

Tjahyadi, Alfred

Abstract:

Friction dampers have been used successfully to dissipate seismic energy in steel and concrete structures. The application is new to timber structures. The objectives of this research were to design a slotted bolted connection (SBC) and evaluate its potential as a passive energy damper in timber brace. The research was...

Experimental and analytical evaluation of conventionally reinforced deck-girder bridge bent caps with vintage details

Creator:

Senturk, Ahmet Ekin

Abstract:

Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...
