Torsional Analysis for Exterior Girders
(University of Kansas Center for Research, Inc., 1999-04)Concrete deck placement imposes eccentric loading on exterior steel bridge girders. This report describes a design tool that aids bridge engineers in evaluating the response of the exterior girder due to this eccentric ... -
Seismic Behavior and Detailing of High-Performance Fiber-Reinforced Concrete Coupling Beams and Coupled Wall Systems
(American Society of Civil Engineers, 2013)The seismic behavior of coupling beams and walls constructed with tensile strain-hardening, high-performance fiber-reinforced concrete (HPFRC) was studied through tests of large-scale precast coupling beams and coupled ... -
Proposed Revisions to the Strength-Reduction Factor for Axially Loaded Members
(American Concrete Institute, 2014)Modifications correct anomalies for nonprestressed reinforced concrete members subjected to flexure and axial loads -
Seismic Response of Fiber-Reinforced Concrete Coupled Walls
(American Concrete Institute, 2016)The behavior of coupled T-shaped structural walls was studied through tests of two large-scale four-story specimens under reversed cyclic lateral displacements. The use of tensile strainhardening, high-performance ... -
A Review of Research on Shear Strength Decay in Members under Load Reversals
(American Concrete Institute, 2016)In the design of reinforced concrete earthquake-resisting frame members, it is critical that shear distress be limited in order to ensure acceptable deformation capacity and reduce damage. Accordingly, several ACI Building ... -
Deformation Capacity and Strength of RC Frame Members with High-Strength Materials
(American Concrete Institute, 2016)Some implications of using high-strength concrete and steel materials in reinforced concrete frame members are discussed in terms of both flexural design and behavior. Through an example, it is demonstrated that the computed ... -
Earthquake-Resistant Squat Walls Reinforced with High- Strength Steel
(American Concrete Institute, 2016)Results are reported from reversed cyclic tests of five large-scale squat wall specimens reinforced with steel bars having a specified yield strength of either 60 or 115 ksi (413 or 792 MPa). Two specimens were designed ... -
Bond of Top-Cast Bars in Bridge Decks
(American Concrete Institute, 1985)The effects of consolidation method and two-course construction on the bond strength of top-cast reinforcement in concrete bridge decks were studied as functions of slump, bleed. and slab depth. Consolidation was varied ... -
Bond of Reinforcement to Superplasticized Concrete
(American Concrete Institute, 1986)The effects of superplasticizers on concrete-steel bond strength were studied. Key variables were degree of consolidation; concrete slump, both with and without a superplasticizer; concrete temperature; and bar position. ... -
Bond of Reinforcement to Revibrated Concrete
(American Concrete Institute, 1986)The effects of revibration on concrete-steel bond strength are studied. Key variables are concrete slump, bar position, and the time interval between initial vibration and revibration. No 8 (25 mm) deformed reinforcing ... -
Strain-Rate Sensitive Behavior of Cemet Paste and Mortar in Compression
(American Concrete Institute, 1990)The strain-rate sensitivity of the cement paste and mortar constituents of concrete is studied experimentally. Saturated cement paste and mortar specimens are loaded in compression to 15,000 microstrains, 27 to 29 days ... -
Bond of Epoxy-Coated Reinforcement: Bar Parameters
(American Concrete Institute, 1991)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 ... -
Development Length Criteria: Bars Not Confined by Transverse Reinforcement
(American Concrete Institute, 1992)An expression that accurately represents development and splice strength as a function of concrete cover and bar spacing is developed. The expression is then used to establish and evaluate modifications to the bond and ... -
Bond of Epoxy-Coated Reinforcement: Splices
(American Concrete Institute, 1993)The effects of epoxy coating and transverse reinforcement on the splice strength of reinforcing bars in concrete are described. A total of 65 beam and slab splice specimens containing No. 6 and No. 8 bars were tested. The ... -
Bond of Epoxy-Coated Reinforcement: Cover, Casting Position, Slump, and Consolidation
(American Concrete Institute, 1994)The effects of concrete cover, casting position, concrete slump, and degree of consolidation on the reduction in bond strength between reinforcing bars and concrete caused by epoxy coating are described. Tests include ... -
Splice Strength of High Relative Rib Area Reinforcing Bars
(American Concrete Institute, 1996)This paper described the testing and analysis of 93 beam-splice specimens containing No. 5, No. 8, and No. 11 (16, 25 and 36mm) bars with relative rib areas (ratio of projected rib area normal to bar axis to the product ... -
Development Length Criteria for Conventional and High Relative Rib Area Reinforcing Bars
(American Concrete Institute, 1996)Statistical analyses of 133 splice and development specimens in which the bars are not confined by transverse reinforcement and 166 specimens in which the bars are confined by transverse reinforcement are used to develop ... -
Bond Strength of Grouted Reinforcing Bars
(American Concrete Institute, 1996)The effects of hole preparation method, grout type, hole diameter, bar size, embedment length, cover, bar surface condition (epoxy-coated or ncoated), orientation of the installed bar, and concrete strength on the bond ... -
Effect of Reinforcing Bar Deformation Pattern on Flexural Ductility
(American Concrete Institute, 1998)Concern has been expressed that increases in the stiffness of the bond force-slip relationship of reinforcing bars, resulting from increases in the relative rib area (Rr) of the bars, may have a negative impact on the ... -
Splice Strength of Conventional and High Relative Rib Area Bars in Normal and High-Strength Concrete
(American Concrete Institute, 2000)The effects of concrete strength, coarse aggregate quantity and type, and reinforcing bar geometry on splice strength are evaluated. Results for 64 splice specimens with reinforcing bars with relative rib areas (ratio of ...
