    ACI 562: Code-Based Approach for Evaluation, Repair, and Rehabilitation of Concrete Structures


    As reinforced concrete materials age, our concrete structures may need to be evaluated for safety based on changes in the operational and occupational use of the facility or the development of corrosion, alkali-silica reaction, or other distress mechanisms. Based on a structural evaluation, strengthening may be necessary and may be accomplished through rehabilitation or replacement. Rehabilitation and repair of existing concrete elements is generally a more sustainable approach than replacement; however, in the past, the lack of code requirements has resulted in variations in repair practice, inconsistent levels of safety and reliability, and no clear direction for building officials and institutional owners.

    The American Concrete Institute (ACI) has developed a repair code that provides standard requirements for evaluating existing concrete buildings and the subsequent structural repair, rehabilitation, and strengthening of those structures. ACI 562 committee member and sub-committee chair, Carl J. “Chuck” Larosche will present a one-hour overview of the development and organization of the new ACI 562 Concrete Repair Code. The presentation will include reasons for and motivation behind the development of the Repair Code, the overall philosophy and organization of the material, the future direction of the Repair Code relative to adoption by the International Code Council as well as the potential concerns for design practitioners involved in repair or rehabilitation of reinforced concrete structures. Additionally, Mr. Larosche will present ACI’s Code approach to determination of unsafe conditions. 

    The 562 Code approach provides the licensed design professional freedom to exercise engineering judgment when evaluating a reinforced concrete structure. Mr. Larosche will present practical examples of structural assessment, existing material evaluation, and load testing of existing structures using the ACI Code approach while illustrating design examples meeting the performance criteria provided in the Code. 

    Speaker Bio

    Carl J. "Chuck" Larosche, P.E. is a Principal at Wiss, Janney, Elstner Associates, Inc. (WJE) in Austin, Texas. Chuck joined WJE in 2004 with more than twenty years of experience specializing in consulting services for the preservation and restoration of historic and existing structures. In addition to his preservation work, Mr.
    Larosche has extensive experience in building envelope, including traditional building materials as well as current state-of-the-art materials.

    Prior to WJE, Mr. Larosche was a Principal of Sparks, Larosche & Associates and worked for The Texas Department of Transportation (TxDOT). Mr. Larosche's diverse background includes structural design, investigation, and evaluation of existing structures and materials. He has successfully combined hisbroad construction background with his knowledge of material behavior in existing structures to provide rare insight and knowledge in the area of masonry, concrete, and steel evaluation, including strengthening and repair of these materials.

    Mass Timber: Products, Performance and Design

    Mark Bartlett, PE - Regional Director - Woodworks - Wood Products Council

    Due to their high strength, dimensional stability and positive environmental performance, mass timber building products are quickly becoming materials of choice for sustainably-minded designers. This presentation will provide a detailed look at the variety of mass timber products available, including glue-laminated timber (glulam), cross laminated timber (CLT), nail laminated timber (NLT), heavy timber decking, and other engineered and composite systems. Applications for the use of these products under modern building codes will be discussed, and examples of their use in U.S. projects reviewed. Mass timber’s ability to act as both structure and exposed finish will also be highlighted, as will its performance as part of an assembly, considering design objectives related to structural performance, fire resistance, acoustics, and energy efficiency. Other topics will include detailing and construction best practices, lessons learned from completed projects and trends for the increased use of mass timber products in the future.
