Abstract:
Explains changes in standard lumber sizes and working stresses, and their effect on design of formwork. Points out availability of new design tables for several grades of lumber. Reports on revisions to Formwork for Concrete to make it consistent with new lumber sizes. Explains generally how SP-4 and ACI 347-68 complement each other in providing guidance for formwork design and construction.
