Book Synopsis Evaluating the Time-dependent Deformations and Bond Characteristics of a Self Consolidating Concrete Mix and the Implication for Pretensioned Bridge Applications by : Kyle H. Larson
Download or read book Evaluating the Time-dependent Deformations and Bond Characteristics of a Self Consolidating Concrete Mix and the Implication for Pretensioned Bridge Applications written by Kyle H. Larson and published by . This book was released on 2007 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of an extensive experimental program conducted to determine the material, bond characteristics, and time-dependent deformations of a proposed self-consolidating concrete (SCC) mixture for bridge girders are presented. This research program was completed in three phases. The first phase consisted of 15 full-scale, pretensioned SCC flexural specimens tested to evaluate their transfer and development lengths. These specimens included both single-strand and multiple-strand beams, as well as specimens designed to evaluate the so-called 'top-strand' effect. The top-strand specimens, with more than 20 inches of concrete below the strand, were tested to evaluate the current American Association of State Highway and Transportation Officials requirement of a 30% increase in the development length when the concrete below the strand is more than 12 inches. Strand end-slip measurements, used to estimate transfer lengths, indicated the proposed SCC mixture meets ACI and AASHTO requirements. In addition, flexural tests confirmed the proposed SCC mixture also meets current code requirements for development length. The second phase was to evaluate the elastic shortening, creep, and shrinkage properties of the proposed SCC mixture for bridge girders. Four bridge girders with an inverted-T profile were used to measure these time-dependent deformations. In two of the specimens, the strands were tensioned to 75% of the ultimate tensile strength, simulating a girder at service. Strands of the other two specimens were left untensioned to evaluate shrinkage effect of the concrete alone. The shrinkage was then subtracted from the fully tensioned specimens and elastic shortening and creep were isolated after relaxation losses were calculated from code expressions. In addition, the fully tensioned specimens were used to determine transfer lengths of the prestressing strand. The final phase of the program was to record strain measurements of the actual bridge girders used in the field. Elastic shortening, creep, and shrinkage prestress losses of the proposed SCC mixture were compared with current design equations. Instrumentation of seven pretensioned girders in a five-span bridge located in Cowley County, Kansas, was used to measure time-dependent deformations. Three of these girders utilized SCC, while the other four were cast with conventional concrete.

Book Synopsis Self-consolidating Concrete for Cast-in-place Bridge Components by : George Morcous
Download or read book Self-consolidating Concrete for Cast-in-place Bridge Components written by George Morcous and published by . This book was released on 2016 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: "National Cooperative Highway Research Program (NCHRP) Report 819: Self Consolidating Concrete for Cast in Place Bridge Components presents recommended guidelines for the use of self-consolidating concrete (SCC) in cast in place highway bridge components. These guidelines address the selection of constituent materials, proportioning of concrete mixtures, testing methods, fresh and hardened concrete properties, production and quality control issues, and other aspects of SCC. The report also presents proposed changes to the AASHTO LRFD Bridge Design and Construction Specifications to address use of SCC for cast in place highway bridge components. The information contained in the report will guide materials and bridge engineers in evaluating, selecting, and specifying SCC mixtures for use in cast in place concrete bridge components, thereby facilitating construction, improving the working environment and safety, and reducing cost."--Publisher's description
