Concrete Formwork System


Formwork development has paralleled the growth of concrete construction

throughout the 20th century. In the last several decades formwork

technology has become increasingly important in reducing overall costs,

since the structural frame constitutes a large portion of the cost of a formwork system.





This book has three objectives. The first is to provide technical

descriptions and evaluations of ten formwork systems that are currently

used in concrete construction. The second is to serve as a tool to assist

contractors in selecting the optimal formwork system. The third is to

present the design criteria for conventional formwork for slabs and walls

using the stress and the stress modification factors provided by the National

Design Specifications (NDS) and the American Plywood Association (APA).

Following a comprehensive introductory chapter, five types of formwork

systems for concrete slabs are presented in chapters 2–5. These

are conventional wood forms, conventional metal forms, flying forms, the

column-mounted shoring system, and tunnel forms. The last four chap-
