The American Concrete Institute (ACI) has released ACI 562-19 Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary.
The code was written to be integrated into building codes for increased confidence that repairs are performed in a manner that provides an acceptable level of protection for the public, according to an ACI new release.
The code was developed to integrate with the International Code Council’s International Existing Building Code or to be adopted as a stand-alone code.
“ACI 562-19 provides owners confidence that their repair projects will be designed to a common standard, engineers a uniform set of requirements specific to existing concrete structures, building officials a basis upon which to evaluate design and construction, and contractors clarification of responsibilities,” says Michael L. Tholen, ACI managing director, engineering and professional development.
Key changes to the 2019 version of the code include:
· Improved integration with ACI 318 Building Code Requirements for Structural Concrete
· Improved integration with the ICC International Existing Building Code
· More context provided regarding durability
· Improved text and commentary related to load combinations during fire events
· Improved text and commentary related to applicability of ACI 562
· Simplified requirements for the basis of design report
· Clarification of requirements related to detailing of existing reinforcing steel
