ACI 347R-14 provides recommendations for the construction and use of formwork, including:
Modern formwork uses aluminum, steel, engineered wood (LVL and plyform), and plastic composites. This chapter outlines allowable stresses, deflection limits (typically L/360 or L/270 depending on the finish), and durability standards for each material. aci 347r14 guide to formwork for concrete pdf
The guide begins by clarifying what formwork includes: It distinguishes between formwork for vertical elements (columns, walls) and horizontal elements (slabs, beams, decks). However, for most conventional concrete work
However, for most conventional concrete work. Many building codes (2021 IBC) reference the 14 version. Unless you use SCC or advanced digital tools, the 2014 guide suffices. The formwork system should be designed to support
The formwork system should be designed to support all loads that will be imposed on it during construction. The primary loads to be considered are:
Formwork terminology can be confusing. This chapter standardizes terms like "sheathing," "studs," "wales," "shores," and "reshores." For non-native English speakers or young engineers, this glossary (often searched within the PDF) is invaluable for reading contract documents.
