Pdf | Aci 347r14 Guide To Formwork For Concrete

The guide outlines safety factors for different formwork components, emphasizing that formwork must hold not only the weight of the concrete but also impact loads, wind loads, and seismic forces [1, 2].

ACI 347R-14 provides detailed guidelines on calculating loads, including vertical loads (weight of concrete, workers, equipment) and horizontal loads (lateral pressure of fresh concrete) [1]. It emphasizes the importance of designing for safety, stiffness, and structural integrity [2].

The weight of the formwork itself plus the weight of the fresh concrete (typically assumed to be 150 lb/ft³ or 2400 kg/m³ for reinforced concrete). aci 347r14 guide to formwork for concrete pdf

Chapters are dedicated to the properties of various materials—such as lumber, plywood, and steel—and the safety factors required for accessories like form ties and anchors.

Formwork must be inspected immediately before, during, and after concrete placement. Inspectors check for tight joints (to prevent grout leakage), stable mudsills, secure ties, and proper alignment.

One of the most heavily cited sections of ACI 347R-14 details the calculation of loads that the formwork must withstand. Formwork must be designed to support all vertical and lateral loads applied during the construction process. Vertical Loads Vertical loads consist of dead loads and live loads: The guide outlines safety factors for different formwork

Ensure your team is working with the most updated information by obtaining the guide directly from the American Concrete Institute.

Note: For detailed, practical application and worked examples, the companion manual is recommended.

Form ties and anchors must possess a predictable ultimate strength. ACI 347R-14 advises that form ties should be designed with a safety factor of 2.0 for standard applications. If the failure of a tie could jeopardize worker safety, higher safety factors must be applied. 4. Construction Practices and Erection
