02.17.15: ACI 562 - Development of a Building Code for Repair of Existing Concrete Structures
The repair of existing concrete structures can represent a significant challenge to design professionals, owners, building officials and contractors. The challenges arise due to a myriad of questions regarding the necessary extent of repairs, responsibilities during the project and uncertainties regarding governing code requirements. The concept of a building code for repair of existing concrete structures has been discussed for nearly thirty years. However, a major sticking point for the development of a concrete repair code was the relationship of a repair code with both ACI 318 and general building codes such as the International Building Code (IBC). The development of the International Existing Building Code (IEBC) has provided design professionals a pathway that delineates code requirements for repair and alterations of existing structures. However, the IEBC does not provide detailed code requirements that address the unique challenges of how to evaluate damaged concrete structures and how to ensure a long-term service life of both the repaired area and the repaired structure.
In 2013, the ACI 562 Code for Evaluation, Repair and Rehabilitation of Existing Concrete Structures (ACI 562) was published by the American Concrete Institute. ACI 562 was specifically developed to provide design professionals with a code for the repair of existing concrete structures and represents the first material specific repair code in US practice and the first code specifically developed to be integrated with the IEBC. ACI 562 includes specific provisions for:
Evaluation of existing structures;
Load and resistance factors;
Design of repairs;
Durability requirements; and
ACI 562 was developed to be performance-based (in contrast to prescriptive) to provide engineers the maximum amount of flexibility in developing repair solutions. The documentís extensive commentary, including a comprehensive list of references, provides guidance to design professionals using the code. The paper and presentation will describe the development of ACI 562, the relationship of ACI 562 with other building codes and the impact of the code on typical concrete repair project.
Keith Kesner PhD, PE, SE is a structural engineer with over 20 years of professional experience in the evaluation of existing structures. He is a Fellow of the American Concrete Institute (ACI) and an active member of the International Concrete Repair Institute (ICRI). He is the author/co-author of over 100 publications and presentations on a variety of structural engineering topics. He was awarded the 2005 ACI Young Member Award for Professional Achievement and co-awarded the 1998 ACI Construction Practice Award. He currently serves as the Chair of ACI Committee 562, and as member of ACI Committees 318-C, 228 and 364.
He is a registered Professional Engineer in several states, and a registered Structural Engineer in Massachusetts, Illinois and Hawaii. He received his Ph.D. and M.S. degrees from Cornell University and his B.S. degree from the University of Connecticut.
