SP11 A collection of seven papers that pinpoint problem areas of concern and their sollutions to architects, engineers, material suppliers, and manufacturers of precast concrete panels.

This report is a London architect's analysis and commentary on various buildings with precast concrete structural walls and precast concrete curtain wulls made on a tour of the United States. British structures are also discussed. Also includes 'Tests for Precast Wall Panels' as reported by Subcommittee V, ACI Committee 533.

Reviews the development of precast concrete wall panels. Discusses early exposed aggregate work, panel shape, use of color, structural panels, sandwich panels, and shocked concrete.

Describes an investigation of the structural behavior of 31 cancrete sandwich panels tested under uniform flexural loading. Panel designs included different types of insulating core materials and different methods of providing positive shear connections between the reinforced concrete shells.

Investigations were made on several existing buildings, and the results analyzed. Some tentative conclusions as to bowing, warpage, and movement are presented here fur further discussion and study.
