Internal curing of high-performance concrete for bridge decks

Creator:: Deboodt, Tyler
Abstract:: High performance concrete (HPC) provides a long lasting, durable concrete that is typically used in bridge decks due to its low permeability, high abrasion resistance, freeze-thaw resistance and strength. However, this type of concrete is highly susceptible to the deleterious effects of both autogenous and drying shrinkage. Both types of...

The effect of boundary geometry on internal density currents in a density stratified reservoir

Creator:: Spurkland, Torbjorn
Abstract:: The effects of boundary geometry on internal density currents in a density stratified reservoir were investigated in a laboratory model. When water was simultaneously withdrawn and admitted to the reservoir, a complex current regime was established. The general flow pattern is described, and the influence of physical variables on the...

Characterization of reinforced fill soil, soil-reinforcement interaction, and internal stability of very tall MSE walls

Creator:: Walters, James J.
Abstract:: In many geotechnical design situations involving tight right-of-way constraints, Mechanically Stabilized Earth (MSE) walls are often the most cost-effective and reliable earth retention technology among available alternatives. However, few well-documented case histories with detailed material testing, instrumentation programs and construction observation of performance are available in the literature. Despite the...

Limit Equilibrium-Based Assessment of the Internal Stability of Geosynthetic Reinforced Soil Structures Subject to Seismicity

Creator:: Loving, Carly K.
Abstract:: Design of Geosynthetic-Reinforced Soil Structures (GRSS) require sufficient rear pullout anchoring capacity in order to maintain internal stability. Length requirements are amplified when reinforcement coverage ratios or seismicity is considered, potentially resulting in uneconomical GRSS design lengths. This study describes the influence of reinforcement length, coverage ratio, and pseudostatic seismic...

Hybridized framing to modify load paths and enhance wood shearwall performance

Creator:: Bultena, Sarah M.
Abstract:: Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, and other geometries. Many heavy timber frames constructed during colonial American times are still standing, exceeding the expected...

Effects of reference displacement and damage accumulation in wood shear walls subjected to the CUREE protocol

Creator:: Langlois, Jeffrey D.
Abstract:: The objectives of this study are: (1) to evaluate the effect of reference displacement on wall behavior under fully reversed cyclic loading using the CUREE test protocol and (2) to assess damage accumulation (visible fastener damage and stiffness degradation) for the imposed drift levels. All tests were conducted on identical...

A practical approach to model the behavior of a metal-plate-connected wood truss system

Creator:: Li, Zhong
Abstract:: Metal-plate-connected (MPC) trusses have traditionally been designed based on a tributary load distribution and a simplified truss model. This design method ignores the load-sharing and composite action in MPC roof truss systems, the semi-rigidity of MPC joints, and joint eccentricity. The main objective of this study was to provide a...

The effect of hold-down misplacement on the strength and stiffness of wood shear walls

Creator:: Lebeda, Dana J.
Abstract:: The objective of this study was to determine the effect of misplaced hold-downs on the static and cyclic behavior of wood shear walls. Three shear wall configurations were considered in this study. The first configuration (control) had hold-downs at the ends of the wall (wall type 1), the second configuration...

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...
