A Finite Element Model to Study the Microscopic Behavior of Plain Concrete
(University of Kansas Center for Research, Inc., 1976-11)The object of this study is to develop a finite element model of non-homogeneous concrete, consisting of mortar and aggregate, for in-plane loading conditions. Linear elastic properties of aggregate and nonlinear properties ... -
Minimum Joint Depth for Moment Frames with High-Strength Materials
(American Concrete Institute, 2023-01-01)This paper reports results from four large-scale interior beam column connections without transverse beams or slabs tested under reversed cyclic displacements. The specimens, which included the first of interior beam-column ... -
Anchorage of High-Strength Reinforcing Bars in Concrete
(University of Kansas Center for Research, Inc., 2023-01)Hooked and headed reinforcing bars are commonly used as a means of shortening development length of reinforcing bars, but a limited amount of previous research has resulted in restrictions on their use in practice. This ... -
Effects of Concrete Tail Cover and Tail Kickout on Anchorage Strength of 90-Degree Hooks
(American Concrete Institute, 2021-11-01)The effects of concrete tail cover and tail kickout on the anchorage strength of hooked bars were investigated. The study included 195 simulated beam-column joint specimens containing two No. 5, 8, or 11 (No. 16, 25, or ... -
Internally-Cured Low-Cracking High-Performance Concrete (IC-LC-HPC) Bridge Decks: Durability and Cracking Performance
(University of Kansas Center for Research, Inc., 2023-01)The laboratory portion of this study investigates the effects of internal curing (IC) water in pre-wetted lightweight aggregates (LWA) between 8.2 and 9.0% and between 12.0 and 13.1% by weight of binder and total internal ... -
Evaluation of Cracking Performance of Bridge Decks Incorporating Nonmetallic Fibers
(University of Kansas Center for Research, Inc., 2022-07)The Minnesota Department of Transportation (MnDOT) identified 20 monolithic (onecourse) bridge decks, constructed between 2015 and 2018, for cracking surveys to investigate the effectiveness of nonmetallic fibers in reducing ... -
Chloride Content and Carbonation of KU Memorial Stadium Cores
(University of Kansas Center for Research, Inc., 2022-08)Three cores were taken from KU Memorial Stadium on 08/17/22 by personnel from Wiss, Janney, Elstner Associates and analyzed for water-soluble chloride content and depth of carbonation. Cores A4 and B4 were taken from ... -
Low-Shrinkage Ultra-High-Performance Concrete
(University of Kansas Center for Research, Inc., 2022-08)Ultra-high-performance concrete (UHPC) has been used increasingly in the past decade due to its high strength, rapid strength gain, and enhanced durability. UHPC is a cement-based material that typically has a low w/cm ... -
