Cover the basics of form design and construction with the new ACI SP-4 7th Edition

Introduction General Objectives in Formwork Building How Formwork affects concrete quality Causes of failures Planning for Safety Relationship of architect, engineer, and contractor Measurement and payment for formwork How the architect-engineer can reduce form costs References Overall Planning Development of a basic system Key areas of cost reduction Planning for maximum reuse Economical form construction Setting and stripping Other costs affected by formwork plan Planning examples Materials, Accessories, Proprietary Products Lumber Engineered wood products Plywood Other framing and facing materials Insulation and insulating forms Hardware and fasteners Prefabricated forms Shoring and scaffolding References Loads and Pressures Vertical loads Lateral pressure of fresh concrete Lateral loads Other loads References Form Design Notation Basic Simplifications Beam formulas Design criteria Bearing examples Wall, slab and beam form design Form accessories Column form design Shoring and scaffolding Bracing for lateral loads Camber and adjustment for settlement References Design Tables Sheating design Joists, studs, beams Double members Wood shores Form design Using the Tables Design tables Formwork drawings General layout and detail drawings Check list of details Recheck of structural drawings Drawing approval Building and Erecting the Formwork Carpentry Shop and Job Mill Footings Slab on grade and paving work Wall forms Column forms Beam or girder forms Slab forms Shoring and Scaffolding BRIDGE FORMWORK Foundations Piers Pier caps and tie struts Superstructures Arch bridges Segmental box girder bridge construction Making precast bridge segments References
