This book was released on 1995 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the limitations of the analytical approach to rating bridges in the current AASHTO specifications, proof-load testing is often a desirable alternative rating method. The study reported here examined the feasibility of a proof-load testing program for New York, addressing both economic and technical aspects. Such a program with clearly defined application areas is found to be cost-effective. Two technical objectives are identified, based on review of current practice elsewhere: 1) prescription of the target proof load, and 2) development of a detailed procedure manual to guide typical proof-load tests. These tasks were completed and the results (including a draft text of the manual) are presented in this report.

Available in PDF, EPUB and Kindle. Book excerpt: Continually increasing demands on infrastructures mean that maintenance and renewal require timely, appropriate action that maximizes benefits while minimizing cost. To be as well informed as possible, decision-makers must have an optimal understanding of an infrastructure’s condition—what it is now, and what it is expected to be in the future. Written by two highly respected engineers, the second volume, Infrastructure Health in Civil Engineering: Applications and Management, integrates the decision making concept into theoretical and practical issues. It covers: State-of-the-art practice and future directions Use of probability and statistics in areas including structural modeling Specific practical applications, including retrofitting and rehabilitation in response to earthquake damage, corrosion, fatigue, and bridge security Use of IHCE for management and maintenance of different types of structures using pre-stressed and reinforced concrete, and fiber-reinforced polymers (FRPs) Numerous practical case studies, as well as coverage of the latest techniques in the use of sensors for damage detection and load testing Built to correspond to the ideas presented in its companion volume, Theory and Components, this is an invaluable guide to optimized, cost-saving methods that will help readers meet safety specifications for new projects, as well as the aging infrastructure at great risk of failure.

It discusses the specific aspects of proof load testing during the preparation, execution, and post-processing of such a test (Part 1). The second part covers the testing of buildings. The third part discusses novel ideas regarding measurement techniques used for load testing. Methods using non-contact sensors, such as photography- and video-based measurement techniques are discussed. The fourth part discusses load testing in the framework of reliability-based decision-making and in the framework of a bridge management program. The final part of the book summarizes the knowledge presented across the two volumes, as well as the remaining open questions for research, and provides practical recommendations for engineers carrying out load tests.

Book excerpt: This report presents preliminary results and a detailed plan for an investigation whose objective is to examine the economics and technology of proof testing of highway bridges. Current practice of highway bridge structural evaluation in the United States and New York State is reviewed. It is noted that current codes do not include provisions for proof testing in bridge structural evaluation, and no standard proof-testing procedures are available. A reliability model is introduced to determine the proof loads required for acceptable structural safety. The framework of a proof-testing procedural manual is also outlined. An economic analysis is summarized including relevant costs and benefits.

Download or read book Load Rating and Evaluation of Two Prestressed Concrete Box Girder Bridges with No Plans Using Non destructive Load Testing written by Dagmawie Degif Shikurye and published by . This book was released on 2014 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridges with no plans are currently an issue in various states including New Mexico as many exist throughout the United States. Since these bridges have no existing plans and documentation, conventional load rating procedures can't be employed. Therefore in this research project, a four step procedure was developed for the load rating of prestressed concrete box girder bridges without plans. First, the total number and eccentricity of the prestressing strands in the bridge beams are estimated using Magnel diagrams. Second, material properties are obtained from the AASHTO Manual for Bridge Evaluation, AASHTO Standard Specifications, and/or the New Mexico provisions. Second, a Hilti PS 250 Ferroscan is used to detect the steel in the prestressed concrete beams and check the strand estimate and also determine the layout of the shear reinforcement. In addition, the concrete strength is estimated using a Windsor probe. Third, a diagnostic load test is performed to evaluate the in-service behavior and to measure the beam strains under a truck load approximately 60% of the target proof load determined based on the prestressing strand estimate and allowable tensile stress at service. Strain measurements are taken at critical locations to monitor the bridge response during the test. The objectives of this test are to determine the critical transverse truck path (i.e., ones producing the largest measured strains) and compare the measurements with analytical predictions. Fourth, a proof load test is conducted following the critical truck paths and under increasing truck loading until the allowable tensile stress or the target proof load is reached (whichever comes first). Results from the proof test are used to determine rating factors for legal loads. The AASHTOWare BrR software program is also used for purpose of comparison with the rating factors from the proof test. Two prestressed concrete box girder bridges in New Mexico located in Doña Ana County (Bridge 7722) and Bernalillo County (Bridge 8825) were evaluated in this study. For Bridge 7722, the BrR design ratings under HS-20 truck loading were computed as 1.073 and 1.791 at the inventory and operating level, respectively. Inventory and operating factors of 0.882 and 1.403, respectively, were obtained for Bridge 8825. These results, in particular the operating ratings greater than 1.0, provided the needed confidence to proceed with the load tests. Based on the results of the proof tests, rating factors were computed for New Mexico and AASHTO legal loads according to the AASHTO Manual for Bridge Evaluations. The lowest rating factors were 1.09 and 1.17 for Bridge 7722 and Bridge 8825, respectively, which showed that the two bridges did not need to be load posted for legal loads.
