Mechanical performance of post-tensioned residential foundation slabs using expansive BCSA cements
(2023-05-12)
Recent research in concrete materials and structural behavior has focused on alternative cements to increase sustainability as cement manufacturing is a leading producer of CO2 emissions. One promising alternative is calcium ...
Development of Non-Proprietary Ultra-High-Performance Concrete Mix Designs
(2017-12)
Ultra-High-Performance Concrete (UHPC) is defined by the Federal Highway Administration (FHWA) as having a compressive strength of 21.7 ksi (kilo-pounds per square inch), a post-cracking tensile strength 0.72 ksi, and high ...
Performance of Fiber-Reinforced Eco-Friendly Concrete for Bridge Structures
(2016-08-12)
Concrete is the leading building material in the world due to its readily available materials, strength, durability, and relatively low cost. With cities growing at a more rapid pace, the demand for concrete is increasing. ...
CHARACTERIZING THE BEHAVIOR OF CONCRETE CAST WITH TYPE K SHRINKAGE COMPENSATING CEMENT WHEN PLACED UNDER MECHANICAL RESTRAINT
(2018-05-12)
The purpose of this research was to determine whether shrinkage-compensating concrete (SCC) made with Type K cement is capable of offsetting the effects of early age drying shrinkage, specifically when the concrete is acted ...
Performance characteristics of selected asphalt mixes : a laboratory and field study
(2006)
A combined laboratory and field study was undertaken to investigate the performance characteristics of some Hot Mix Asphalt (HMA) mixes that are commonly used by Oklahoma Department of Transportation (ODOT). Four different ...
Development of a Verified Non-Linear Winkler Model for the Seismic Analysis of Piles in Improved Ground
(2019-12-13)
Several ground improvement techniques that are proven to be effective and economical solutions to increase the lateral stiffness and strength of weak soils around piles often result in unwarranted conservative volumes of ...
Design of single plate framing connections
(1992)
The single plate framing connection is one of the simplest and most economical beam to column or beam to girder connections. The connection is comprised of a single plate, with either prepunched or predrilled bolt holes ...
THE EFFECTS OF CASTOR CANADENSIS (NORTH AMERICAN BEAVER) COLONIZATION ON A MINE DRAINAGE IMPACTED STREAM
(2017-12)
This study investigated four aspects of North American Beaver (Castor canadensis) colonization: (1) retention of metals in-stream due to the presence of dams, (2) metals contamination and leachability of sediments (3) ...
Real-Time Hybrid Simulation Study of a Rolling Pendulum Equipment Isolation System
(2021-05-14)
Damage caused by earthquakes to buildings and their contents (e.g., sensitive equipment) can impact life safety and disrupt business operations following an event. The resulting social and economic losses can be minimized, ...
Investigation of the Effects of End Region Deterioration in Precast, Prestressed Concrete Bridge Girders
(2016)
An important factor in life expectancy of concrete bridges is the effect of corrosion of reinforcing steel on concrete and appurtenant embedded materials. New bridges, though continuously exposed to the elements, are ...
