Evaluating the behavior of axial lap steel connections made in combination of slip-critical bolts and longitudinal fillet welds under direct tension and fatigue
(2021-07)
Steel building and bridge connections have traditionally relied on either bolts or welds only to carry the required load from member to member. Due to the historical use of bolts or welds only, the combination of bolts and ...
Reducing shrinkage through admixtures and aggregate gradation
(2021-05)
A study was conducted into the impacts of shrinkage reducing admixtures (SRAs) and larger nominal maximum coarse aggregate sizes on the properties and performance of concrete mixtures. Bridge deck concrete mixtures with ...
Performance based testing for air entrainment and total heat of reclaimed fly ash
(2021-07)
As coal combustion energy plants are being converted to natural gas, the tons of fly ash produced in the United States has dramatically decreased. The current demand in fly ash supply can be mitigated with the introduction ...
Factors that influence end zone cracking in pre-tensioned prestressed concrete bridge beams - A finite element analysis
(2021-05)
The basic problem studied as part of this master's thesis work consists of two main parts.
Effects of trace metals on chloraminated disinfection byproduct formation of drinking water biofilms
(2021-07)
The use of disinfecting chemicals on public water supplies is a practice conducted around the world today. Disinfectants such as chlorine, chloramine, and ozone can be added to a water supply to eliminate any bacteria and ...
Use of fibers to improve the performance of concrete
(2021-05)
This work creates a simple test method to determine the effectiveness of macro synthetic fibers and steel fibers inside concrete by analyzing data from laboratory mixtures with a series of different fiber types and dosages. ...
