ACI PRC-215-21 (IN-LB, SI) PDF Download

The ACI PRC-215-21 (IN-LB, SI) standard provides valuable information for engineers involved in the design or rehabilitation of concrete structures that are subjected to high-cycle fatigue. High-cycle fatigue refers to stress cycles in which the material behavior remains within the elastic range. This standard focuses on the effects of repeated loads on different types of concrete elements, including plain concrete, reinforcing materials, and reinforced concrete systems.

The purpose of this standard is to serve as a general resource, offering a comprehensive overview of fatigue issues specifically related to reinforced concrete structures. It does not provide detailed design procedures, but rather aims to provide engineers with a solid understanding of the challenges associated with fatigue in concrete structures.

Concrete elements that may be subject to high-cycle fatigue include airport and roadway pavements, bridge girders, bridge decks, wind turbines, and prestressed concrete railroad ties. The standard draws on available literature to discuss the effects of repeated loads on these structures.
