Fracture Energy of High-Strength Concrete
(American Concrete Institute, 2001)The effects of water-cementitious materials ratio, age, and aggregate type on the compressive strength, flexural strength, and fracture energy of concretes with compressive strengths ranging from 20 to 99 MPa (2900 to ... -
Bond of Epoxy-Coated Reinforcement: Coefficient of Friction and Rib Face Angle
(American Concrete Institute, 1999)The coefficients of friction between epoxy-coated and uncoated reinforcing steel and mortar and the effects of rib face angle on the relative bond strength of epoxy-coated bars are determined. Results for 130 test specimens ... -
Concrete in Compression
(American Concrete Institute, 1999)One hundred years ago, engineers were debating whether density, aggregate gradation, or water cement ratio controls the strength of concrete. Today, those debates have been settled, but the factors that control the behavior ... -
Bond Slip of High Relative Rib Area Bars under Cyclic Loading
(American Concrete Institute, 2000)The load-slip behavior of high relative rib area and conventional reinforcing bars subjected to reversed cyclic loading is compared. No. 8 (No. 25) production reinforcing bars with relative rib areas of 0.119 and 0.085 are ... -
How to Write a Good Technical Paper
(American Concrete Institute, 2001)The ability to communicate is a critical skill that not only affects our success as professionals, but also determines how effectively lessons from the laboratory and field are transferred into general practice. As members ... -
Experimental Evaluation of Design Procedures for Shear Strength of Deep Reinfoced Concrete Beams
(American Concrete Institute, 2002)In this paper, results from the monotonic testing of four reinforced concrete deep beams are presented. The behavior of the deep beams is described in terms of cracking pattern, load-versus-deflection response, failure ... -
Reduction of Column Yielding During Earthquakes for Reinforced Concrete Frames
(American Concrete Institute, 2003)An investigation to reduce the number of columns that are vulnerable to yielding in reinforced concrete frames subjected to earthquakes is described. Simple limit analysis is used to demonstrate that a reasonable minimum ... -
Design of Simply Supported Deep Beams Using Strut-and-Tie Models
(American Concrete Institute, 2003)A procedure to calculate the amount of reinforcement and the strength of deep beams based on strut-and-tie models is presented. The proposed design equations were calibrated using experimental results from 175 simply ... -
Flat-Rate Design Method for Low- and Medium-Rise Reinforced Concrete Structures
(American Concrete Institute, 2004)A simplified procedure to proportion earthquake-resistant reinforced concrete structures without irregularities is presented. The flatrate method may also be used to assess the vulnerability of existing structures to ... -
Drift-Dependent Confinement Requirements for Reinforced Concrete Columns Under Cyclic Loading
(American Concrete Institute, 2004)The influence of transverse reinforcement and axial load on the drift limit of rectangular columns was investigated using test results from 184 specimens subjected to cyclic loading. Columns within the set were selected ... -
Effect of Epoxy Coating Thickness on Bond Strength of Reinforcing Bars
(American Concrete Institute, 2003)The effect of epoxy coating thickness on bond strength is evaluated using No. 19 (No. 6) reinforcing bars with coating thicknesses ranging from 160 to 510 mm (6.4 to 19.9 mils). Three deformation patterns are evaluated ... -
Rapid Development of ACI Documents
(American Concrete Institute, 2004-11)ACI has taken several steps to permit technology to be transferred more rapidly than in the past. ITGs, with their limited mission and lifetime, represent one of the tools for accomplishing this goal through the rapid ... -
Recommended Provisions and Commentary on Development and Lap Splice Lengths for Deformed Reinforcing Bars in Tension
(American Concrete Institute, 2005)Criteria recommended by ACI Committee 408 on development and lap splice length design for straight reinforcing bars in tension are presented in code format and compared with those in ACI 318-05, Building Code Recommendations ... -
How to Prepare a Good Technical Presentation
(American Concrete Institute, 2006-02)The ability to give a good technical presentation is an important skill for designers, researchers, and contractors. It’s a skill that must be learned, and therefore, it must be practiced. Remember to tailor your talk to ... -
Effect of Cracking on Chloride Content in Concrete Bridge Decks
(American Concrete Institute, 2006)Field surveys to measure bridge deck cracking and chloride contents of uncracked as well as cracked concrete were performed as a part of a larger research program evaluating bridge deck performance. Three deck types were ... -
Effects of Deicers on Concrete Deterioration
(American Concrete Institute, 2008)Concrete specimens were exposed to weekly cycles of wetting and drying in distilled water and in solutions of sodium chloride (NaCl), calcium chloride (CaCl2), magnesium chloride (MgCl2), and calcium magnesium acetate (CMA) ... -
Critical Chloride Corrosion Threshold of Galvanized Reinforcing Bars
(American Concrete Institute, 2009)The chloride content required for corrosion initiation of galvanized reinforcing bars is determined. The bars conform to ASTM A767, except that no chromate treatment was applied to allow the degree of hydrogen evolution ... -
Lightweight Aggregate as Internal Curing Agent to Limit Concrete Shrinkage
(American Concrete Institute, 2011)The effectiveness of prewetted, vacuum-saturated (PVS) lightweight aggregate (LWA) as an internal curing agent to reduce concrete shrinkage is evaluated for curing periods of 7 and 14 days. Normalweight aggregate is replaced ... -
Performance Evaluation of Corrosion Protection Systems for Reinforced Concrete
(University of Kansas Center for Research, Inc., 2017-01)In this study the performance of corrosion protection systems for reinforced concrete is evaluated. Conventional bare and epoxy-coated reinforcement are compared with alternative forms of reinforcement–galvanized steel, ... -
