This guide provides recommendations for the design, construction, and materials used in concrete formwork. It prioritizes objectives like safety, quality, and economy Key Sections:

Formwork can account for over 50% of the total cost of a concrete structure. Following ACI guidelines helps engineers design more efficient systems. aci 34714 pdf

The application of ACI 347-14 to excavation support is best understood through the lens of load path continuity. When an excavation is opened, the soil’s natural state of equilibrium is disturbed. The potential for cave-ins creates a lateral load that must be transferred to a support system. The standard’s guidance on formwork acts as a surrogate framework for understanding these lateral forces. For instance, the design of wales and struts in a trench box or a sheet pile system mirrors the design of wales and ties in a vertical concrete form.

: The materials chapter was updated to reflect current material design specifications, including changes in wood design from the American Wood Council. The standard’s guidance on formwork acts as a

If you obtain a legal copy of the ACI 347-14 PDF, here is the critical knowledge you will unlock.

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.

ACI 347-14 continues to endorse the method for formwork, which is preferred over Load and Resistance Factor Design (LRFD) for temporary structures due to its simplicity and historical reliability. It provides specific allowable stresses for lumber, plywood, and steel used in forming.
