Description / Abstract:
The 8th Edition, authored by David W. Johnston, North Carolina
State University, is a major revision of the document to bring it
up-to-date with "Guide to Formwork for Concrete (ACI 347R-14)."
Revisions include referencing current standards and practices,
removing outdated or irrelevant material, adding content on new
developments in formwork technology and practice, and updating the
look and layout of the document.
This edition considers the updated lateral pressure and other
provisions now provided by ACI 347R-14. Expanded coverage is
provided in SP-4 for wind loads on formwork specialized from
ASCE/SEI 7-10 as modified by ASCE/SEI 37-14. The design of formwork
has been divided into two chapters, one focusing on bending, shear,
and deflection of wall, slab, and column formwork members, and a
second focusing on shoring and bracing members. Bridge formwork
considerations have been moved into a separate chapter. A new
chapter summarizing the recommendations of ACI 347.3R-13, "Guide to
Formed Concrete Surfaces," has been added.
