Comprehensive Guide to ACI 347.1R-14: Guide for Shoring/Reshoring of Concrete Multistory Buildings aci 34714 pdf
The ACI 347-14 guide is organized into 10 comprehensive chapters that walk the user through the entire lifecycle of formwork from design to removal. The official table of contents from the ACI store provides a clear roadmap of the document's structure:
What (e.g., plywood, modular steel) are you planning to use?
This is the most referenced section. The guide details minimum design loads for formwork, including: Contractors want to strip forms as fast as
ACI 347.14 PDF is a comprehensive guide to precast concrete construction, providing guidelines for design, fabrication, and erection. The guide is essential for ensuring that precast concrete structures meet the required standards of quality, safety, and durability. Precast concrete has several benefits, including speed of construction, quality, durability, and cost-effectiveness. Its applications are diverse, ranging from building frames to highway construction.
The document provides guidance on:
ACI 347.1R-14 outlines methods for calculating these loads. While simplified methods assume rigid shoring and infinitely stiff slabs, the guide encourages a refined analysis using structural software. This ensures that the structural capacity of an early-age concrete slab is never exceeded by the construction demands placed upon it. 4.

Guidelines for slipforming, precast, and lift-slab construction. Importance of ACI 347-14 in Construction
ACI 347R-14 serves as a guide rather than a strict code, providing recommendations for safe and efficient formwork design and construction. This 2014 version replaced previous iterations, offering updated, comprehensive guidelines for modern construction practices.
The manual focuses heavily on the tri-party mandate of modern concrete operations: .
