ACI SP-4: Formwork for Concrete

This document serves a broad range of information needs with the objective of improving quality, safety, and economy in all types of formwork. For the experienced designer or builder of formwork, it is a ready reference on material properties, design data, and construction suggestions. For the architect or engineer, it adds guidance relating to structural design details and the problems and possibilities of executing them in formwork. For the novice, the book explains basic design principles and provides an introduction to many common formwork practices. This edition includes new material on single-sided wall forms, insulating concrete forms, pressure formulas with coefficients for differing weights and mix chemistries, inflated forming methods, and expanded text on multistory shoring systems. Keywords: architectural concrete; construction materials; falsework; folded plate; formwork (construction); mass concrete; precast concrete; prestressed concrete; quality control; reinforced concrete; shells (structural forms); tunnels.
