Steel and Composite Beams With Web Openings
(University of Kansas Center for Research, Inc., 1990-06)Three design methods, osiginally deveIoped by Donahey and Darwin (19861, for dewmining the maximum shear capacity of composite beams with unreinforced web openings are extended to include steel and composite beams with or ... -
Role of Silica Fume in Compressive Strength of Cement Paste, Mortar, and Concrete
(University of Kansas Center for Research, Inc., 1990-04)Controversy exists as to why silica fume increases the strength of concrete when it is used as a partial replacement for cement. Some evidence supports the view that the increase in strength is due to an increase in the ... -
Bond of Epoxy-Coated Reinforcement to Concrete: Bar Parameters
(University of Kansas Center for Research, Inc., 1990-01)The effects of coating thickness, deformation pattern, and bar size on the reduction in bond strength between reinforcing bars and concrete caused by epoxy coating are described. Tests include beam-end and splice specimens ... -
The Effect of Crack Depth on Elastic-Plastic Fracture Toughness in Blend-Bar Specimens
(University of Kansas Center for Research, Inc., 1989-10)Short crack test specimens (a/W < < 0.50) are frequently employed when conventional deep crack specimens are either inappropriate or impossible to obtain, for example, in testing of particular microstructures in weldments ... -
Cyclic Behavior of High Strength Concrete Beams
(University of Kansas Center for Research, Inc., 1988-08)Four high strength, lightly reinforced concrete beams were fabricated and tested to evaluate member response under severe cyclic loading. Concrete strengths varied from 11 • 31 0 to 12,860 psi with reinforcement ratios of ... -
Submicroscopic Deformation in Cement Paste and Mortar at High Load Rates
(University of Kansas Center for Research, Inc., 1988-04)Submicroscopic cracking and strain-rate response of cement paste and mortar under uniaxial 11 compression were measured and correlated with applied strain. Cement paste specimens with water-cement ratios of 0.3, 0.4, 0.5, ... -
Joint Design for Reinforced Concrete Buildings
(University of Kansas Center for Research, Inc., 1987-12)This report discusses construction, contraction and expansion joints in reinforced concrete buildings. The report addresses the purpose of each type of joint and emphasizes the selection of joint locations and joint spacings. ... -
Performance and Design of Composite Beams With Web Openings
(University of Kansas Center for Research, Inc., 1986-04)Fifteen tests to failure were carried out on full scale composite beams with web openings. All beams had ribbed slabs using formed steel deck. Ribs were perpendicular to or parallel to the steel section. The effects of ... -
Submicroscopic Cracking of Cement Paste and Mortar in Compression
(University of Kansas Center for Research, Inc., 1985-11)Submicroscopic cracking of cement paste and mortar under uniaxial compression is measured and correlated with applied strain and load history. Cement paste specimens with water-cement ratios of 0.7, 0.5 and 0.3 were subjected ... -

Preliminary Study of the Effect of Revibration on Concrete-Steel Bond Strength
(University of Kansas Center for Research, Inc., 1984-11)The effects of revibration on concrete-steel bond strength are studied. Key variables are concrete slump, bleed, bar position, and the time interval between initial vibration and revibration. lt8 deformed reinforcing bars ... -
Cracking and Chloride Contents in Reinforced Concrete Bridge Decks
(University of Kansas Center for Research, Inc., 2005-02)The effects of material properties, design specifications, construction practices, and environmental site conditions on the performance of reinforced concrete bridge decks are evaluated. Field surveys were performed on 59 ... -
Field Instrumentation and Analysis of the Tuttle Creek Bridge
(University of Kansas Center for Research, Inc., 2005-04)Fatigue cracking has been an extensive problem for many steel bridges designed prior to the identification of fatigue-prone details. Distortion in bridges coupled with stress concentrations within bridge components can ... -
Corrosion Resistance of Duplex Stainless Steels and MMFX Microcomposite Steel for Reinforced Concrete Bridge Decks
(University of Kansas Center for Research, Inc., 2005-12)Chloride-induced corrosion of reinforcing steel in concrete is one of the major durability concerns in reinforced concrete structures. In Northern America, the cost of maintenance and replacement for highway bridges due ... -
Evaluation of Multiple Corrosion Protection Systems and Stainless Steel Clad Reinforcement for Reinforced Concrete
(University of Kansas Center for Research, Inc., 2006-01)The corrosion performance of multiple corrosion protection systems and stainless steel clad reinforcement is compared and evaluated in this study. Conventional steel and conventional epoxy-coated steel coated with 3M™ ... -
Negative Moment Region Shear Strength of Lightly Reinforced T-Beams
(University of Kansas Center for Research, Inc., 1984-06)The negative moment region shear strength of lightly reinforced concrete T-beams is studied. Nine restrained T-beams with and without web reinforcement were tested. The primary variables were the longitudinal reinforcement ... -
Cyclic Behavior of Lightly Reinforced Concrete Beams
(University of Kansas Center for Research, Inc., 1984-06)The cyclic behavior or seven lightly reinforced concrete cantilever beams is studied as a function of reinforcement ratio, nomina 1 stirrup capacity, stirrup spacing, and ratio of positive to negative reinforcement. An ... -
Effect of Superplasticizers on Concrete-Steel Bond Strength
(University of Kansas Center for Research, Inc., 1984-04)The effects of superp 1 asti ci zers on concrete-steel bond strength are studied. Key variables are degree of consolidation, concrete slump, both with and without a superplasticizer, concrete temperature, and bar position. ... -
