Abstract

Preface The use of Fiber-reinforced polymer (FRP) composite materials in new construction and repair of concrete structures has been growing rapidly in recent years. FRP provides options and benefits not available using traditional materials. The promise of FRP materials lies in their high-strength, lightweight, noncorrosive, nonconducting, and nonmagnetic properties. ACI Committee 440 has published several guides providing recommendations for the use of FRP materials based on available test data, technical reports, and field applications. The aim of these document is to help practitioners implement FRP technology while providing testimony that design and construction with FRP materials systems is rapidly moving from emerging to mainstream technology. In addition to this publication, ACI Committee 440 organized four special technical sessions entitled “Towards Sustainable Infrastructure with Fiber Reinforced Polymer Composites,” two sessions at the ACI Fall 2014 Convention in Washington, DC, on October 26, 2014, and two sessions at the ACI Spring 2015 Convention in Kansas City, MO, on April 13, 2015. These sessions provided a worldwide state-of-the-art forum for researchers, civil/structural engineers, contractors, consultants, practitioners, and regulatory authorities to exchange recent advances in both research and practice, and to share information, experience, and knowledge in the implementation of FRP technology. The technical papers presented at the sessions and published in this volume included the most recent analytical and experimental research work as well as selected field applications, design, and construction guidelines. The sessions were well attended and generated substantial technical discussion and exchange of new technology. Attendees were able to: a) Learn about the wide usage of FRP in new construction and repair of concrete structures b) Understand the design process available in several design guidelines that provides recommendations for the use of FRP materials based on available test data, technical reports, and field applications c) Demonstrate how to evaluate existing structures prior to strengthen/rehabilitation using FRP d) Recognize examples of the types of evaluation that can be performed on existing structures This Special Publication consists of a total of 22 papers, of which 13 papers were presented in the four special sessions sponsored by ACI Committee 440 at the ACI Fall 2014 and the ACI Spring 2015 conventions. These papers are SP-322—3, SP-322—4, SP-322—5, SP-322—9, SP-322—10, SP-322— 11, SP-322—12, SP-322—13, SP-322—14, SP-322—15, SP-322—16, SP-322—17 and SP-322—18.

Hawileh, American University of Sharjah, Sharjah, United Arab Emirates In accordance with the standard review procedures established by ACI, all papers were reviewed by at least four experts in the subject area and approved for publication. All submitted papers were given serious consideration before a decision regarding publication was made. This volume could not have been put together without the, dedication, cooperation, and assistance of many volunteers and ACI staff members. First, we would like to thank the authors for meeting our various deadlines for submission. We are also grateful to the many distinguished reviewers and members of ACI Committee 440 who have carefully evaluated and thoroughly reviewed the technical papers, and whose input and advice have been a contributing factor to the success of this volume. Last, but not least, this symposium is dedicated to the memory of Professor Khaled A. Soudki and I am pleased to offer this symposium as a tribute to an internationaly distinguished researcher in the field of using FRP in concrete structures. Khaled leaves behind a legacy of scientific research all over the world. He will always be remembered for his contribution to civil engineering, and we will all miss him dearly.
