Page Count: 24
scope:

This document provides recommendations for design details and structural framing guidelines to mitigate, control, or distribute crack development in concrete members and structural systems. The recommendations and guidelines are presented in terms of concepts and effective practices that have been successfully implemented to mitigate and control cracking. Specific reinforcement details are presented for some situations, but not all, as the document is intended to illustrate concepts and approaches rather than to provide comprehensive details for all situations.

The reinforcement details shown in this document are for Grade 60 deformed steel reinforcing bars. Note that these reinforcement details may not be sufficient when other types of reinforcement are used, and in particular where the elastic properties (for example, fiber-reinforced polymer), bond properties, or strength of the bars are different.

This document specifically excludes the review of concrete member cracking due to unique or special materials used, concrete mixture proportions, or placing and finishing practices. The design details presented herein are limited to building structures and may not apply to special structures or nonbuilding structures. This document is limited to castin- place concrete frames only, not to precast concrete and masonry elements.
