The Post-Tensioning Institute’s (PTI) third edition of Design of Post-Tensioned Slabs-on-Ground incorporates extensive editorial revisions and clarification
The Post-Tensioning Institute’s (PTI) third edition of Design of Post-Tensioned Slabs-on-Ground incorporates extensive editorial revisions and clarification in its focus on geotechnical design parameters. Outlined are procedures guiding the user to applicable design systems with knowledge of their limitations. For qualified geotechnical and structural engineers, the new technical guide covers design of both ribbed and uniform-thickness post-tensioned, ground-supported foundations.
The manual is divided into eight chapters and six appendices. Topics include Slabs-on-Stable Soils, Geotechnical Investigation, Soil-Structure Interaction and Structural Design Procedure for Shallow Post-Tensioned Foundations. Appendices 3, 4 and 5 provide design examples of residential foundations, all on expansive soil in different climatic situations: dry, wet, and extreme suction profiles. Articulating the entire design process, the examples include plan layouts as well as formulas for completion.
The manual was developed by the PTI Slab-on-Ground Committee chaired by Kenneth Bondy, P.E., S.E. Committee membership from throughout the post-tensioning industry comprises structural engineers, geotechnical engineers and members of the academic community. Design of Post-Tensioned Slabs-on-Grade is available for $41.50 (PTI members) or $59.50 (public) plus shipping.
