The guide covers acceptable materials, including:
The process of placing shores under a stripped member after the original forms have been removed, allowing the new concrete to deflect and support its own weight.
Adherence to ACI 347-14 minimizes the risk of formwork failure and ensures that structural concrete meets the specified architectural and engineering requirements [31, 32]. Reference Resources aci 34714 pdf

Imagine you are a project engineer. Tomorrow, your crew is pouring a 20-foot-high concrete wall. The pump truck will pour at 60 cubic yards per hour, the concrete temperature is 60°F, and the slump is 5 inches. Formwork must support more than just the weight
For engineers and contractors, the search for "ACI 347.14 pdf" is about much more than a file. It's about the critical goal of ensuring that concrete formwork is safe, economical, and of high quality. ACI 347R-14(21) is the definitive, authoritative resource to achieve that goal.
: Emphasizes the need for professional inspection before and during the concrete pour to verify that formwork matches the design drawings. 6. Conclusion
Ensure you are using the correct, updated version ( 347R-14 ) rather than an obsolete older version, to maintain compliance with modern safety standards. Conclusion
Provides comprehensive guidance for contractors, engineers, and inspectors on designing, erecting, using, and removing formwork for concrete structures. Focuses on safety, economy, and quality. | | Guide for Shoring/Reshoring of Concrete Multistory
The document is structured to cover all aspects of formwork, including:
Provisions for calculating loads (dead and live), including the lateral pressure of fresh concrete on forms. Construction Procedures:
