Long-term Implications of Redecking Bridges with Prestressed Concrete Girders
(University of Kansas Center for Research, Inc., 2024-03)Precast/prestressed concrete girders with cast-in-place decks are commonly used for bridge construction throughout the United States. There is a need to replace concrete decks on many of these bridges because girders last ... -
Bond Behavior of Epoxy-Coated Reinforcing Bars in Non-Proprietary UHPC
(Oklahoma Department of Transportation, 2023-10)Non-proprietary ultra-high-performance concrete (UHPC) mixtures were developed for use in closure strips between precast members on reinforced concrete bridges. The mixtures contained ODOT approved Type I portland cement, ... -
Construction of Low-Cracking High-Performance Bridge Decks Incorporating New Technology Phase II
(Kansas Department of Transportation, 2023-12)The construction, crack surveys, and evaluation of 12 bridge decks with internal curing provided by prewetted fine lightweight aggregate and supplementary cementitious materials following internally cured low-cracking ... -
DATASET: Test Results from Shake Table Tests of Reinforced Concrete Frames with Grade 60 or 100 (420 or 690) Reinforcement
(University of Kansas, 2023-12-13)This dataset reports the acceleration and displacement data collected during tests of two reinforced concrete frames that differed in one way: the longitudinal bars were Grade 60 (420) in C1 and Grade 100 (690) in H1. The ... -
Chord Rotation Capacity and Strength of Diagonally Reinforced Concrete Coupling Beams
(American Concrete Institute, 2023-11)A database of results from 27 tests of diagonally reinforced concrete coupling beams was analyzed to develop improved force-deformation envelopes (backbone curves) for modeling and analysis of coupling beams. The database, ... -
Effect of the Variation of Structural Parameters on the Vibrational Characteristics of Steel Joist-Concrete Slab Floor Systems and Suggested Designs
(University of Kansas, 1968-08-31) -
A STUDY OF VARIOUS DEVICES FOR CONTROLLING VIBRATING FLOOR SYSTEMS
(University of Kansas Center for Research in Engineering Science, 1962-05-31) -
VIBRATION OF STEEL BEAM CONCRETE SLAB FLOOR SYSTEMS
(University of Kansas Center for Research in Engineering Science, 1969-03-03)This report deals with the research to date (April, 1968) conducted on the vibration of steel beam-concrete slab floor systems. -
VIBRATION OF STEEL JOIST-CONCRETE SLAB FLOOR SYSTEMS
(University of Kansas Center for Research in Engineering Science, 1962-08)Increased usage of lighter types of construction in floors in recent years for economy purposes has resulted in occasional floors with insufficient stiffness to prevent noticeable vibration induced by human impact. This ... -
EFFECT OF THE VARIATION OF STRUCTURAL PARAMETERS ON THE VIBRATIONAL CHARACTERISTICS OF STEEL JOIST CONCRETE SLAB FLOOR SYSTEMS AND SUGGESTED DESIGNS
(University of Kansas Center for Research in Engineering Science, 1968-08)The overall objective of these investigations is, of course, to provide sufficient information to allow the design of better (less annoying) floor systems and to allow the elimination of annoying vibrations in present floor ... -
In-plane Extended Nano-coulter Counter (XnCC) for the Label-free Electrical Detection of Biological Particles
(Wiley, 2022-06-14)We report an in-plane extended nanopore Coulter counter (XnCC) chip fabricated in a thermoplastic via imprinting. The fabrication of the sensor utilized both photolithography and focused ion beam milling to make the ... -

Urbanization as a limiter and catalyst of watershed-scale sediment transport: Insights from probabilistic connectivity modeling
(Elsevier, 2023-10-10)The conversion of rural lands to urban areas exerts considerable influence on the hydrologic processes governing sediment transport at the watershed scale. While the effects of urbanization on hydrology have been well-studied, ... -
Subthreshold white noise vibration alters trembling sway in older adults
(Elsevier, 2023-06-28)Background Somatosensory deficit is a significant contributor to falls in older adults. Stochastic resonance has shown promise in recent studies of somatosensation-based balance disorders, improving many measures of ... -
Data-driven prognosis of failure detection and prediction of lithium-ion batteries
(Elsevier, 2023-10-15)Battery prognostics and health management predictive models are essential components of safety and reliability protocols in battery management system frameworks. Overall, developing a robust and efficient fault diagnostic ... -
Output force and ratio of laparoscopic graspers: an evaluation of operating room ergonomics
(Elsevier, 2023-05-15)Background “Laparoscopist's thumb,” or thenar paresthesia, can result from prolonged or excessive grip force during laparoscopy, as can more general syndromes, such as carpal tunnel syndrome. This is particularly relevant ... -
An index for inferring dominant transport pathways of solutes and sediment: Assessing land use impacts with high-frequency conductivity and turbidity sensor data
(Elsevier, 2023-10-10)Land use change threatens aquatic ecosystems through freshwater salinization and sediment pollution. Effective river management requires an understanding of the dominant hydrologic pathways of sediment and solute delivery. ... -
Evaluation of Multiple Corrosion Protection Systems for Reinforced Concrete Bridge Decks
(University of Kansas Center for Research, Inc., 2023-07)This study evaluated the corrosion resistance of epoxy-coated (ASTM A775), hot-dip galvanized (ASTM A767), and continuously galvanized (ASTM A1094) reinforcement, and the conventional reinforcement (ASTM A615) used to ... -
Effects of Total Internal Water Content on Freeze-Thaw Durability and Scaling Resistance of Internally-Cured Concrete
