formwork failure. Similarly, scaffolding is important for the safety of
workers and their efficiency.
Chapter 7, Failures of Formwork, addresses the important issue
of the safety of formwork systems. Formwork failure is costly, in
terms of both the physical losses at the jobsite and injuries to workers.
Physical losses include the loss of materials that are destroyed in the
failure and the time and expenses that must be incurred to clean up
and reinstall the forms. Injuries and loss of life of workers create suffering
of people and can lead to costly legal actions.
Chapter 8, Forms for Footings, provides information related to the
design and construction of forms for footings and the fundamental
equations that can be used in the design process. Information is also
included for placing anchor bolts in concrete foundations.
Chapter 9, Forms for Walls, addresses the design of forms for concrete
walls. Equations and tables are presented to facilitate the design
of continuous walls and for walls with corbels. Due to the height of
walls, the pressure at the bottom of the forms is significant. Therefore,
the designer must carefully evaluate the loads that are applied to wall
forms to ensure that the forms have sufficient strength to resist the
applied load. Accessories for walls including snap ties, coil ties, and
form clamps are also presented.
Chapter 10, Forms for Columns, addresses the design of forms for
concrete columns. Included in this chapter are square, rectangular,
round, and L-shaped columns. Column forms may be made of wood,
steel, or fiberglass. Because columns are generally long in height, the
pressure of the concrete at the bottom of the forms is an important
consideration in the design of forms for concrete columns.
Chapter 11, Forms for Beams and Floor Slabs, presents relevant
information on that subject. The size, length, and spacing of joists are
addressed considering the strength and deflection criteria. Spacing of
shores under beam bottoms and details for framing beams into girders
are also presented.
Chapter 12, Patented Forms for Concrete Floor Systems, is devoted
to such patented forms. Patented forms are commonly used for floor
systems because considerable savings in labor cost can be derived by
simply erecting and removing standard forms, rather than fabricating
forms at the jobsite.
Chapter 13, Forms for Thin-Shell Roof Slabs, addresses thin-shell
roof slabs. Roofing systems that consist of thin-shell reinforced concrete
provide large clear spans below the roof with efficient use of
concrete. These types of roofs also produce aesthetically pleasing
appearances for the exterior of the structures.
Chapter 14, Forms for Architectural Concrete, considers architectural
concrete. There are numerous techniques that can be applied to
forms to produce a variety of finishes to the concrete surface after the
forms are removed. For concrete buildings, the appearance of the
completed structure is often a major consideration in the design of
