Comments on the Post-Tensioning Institute's "Design of Post-Tensioned Slabs-on-Ground"

The objective of this document is to provide constructive comments to the Post-Tensioning Institute's (PTI's) Slab-on-Ground Committee and to inform geotechnical and foundation design engineers of the Foundation Performance Association's (FPA's) concerns regarding the Post-Tensioning Institute’s “Design of Post-Tensioned Slabs-on-Ground”, (PTI Design Procedure) 3rd Edition [13].
The PTI Design Procedure is used to design a slab-on grade foundation that will respond elastically to forces the foundation is exposed to including those that are the consequence of soil pressure and soil deformation. This procedure is based on empirical data, computer generated curve fits, the geotechnical engineer’s computation of ym and em values and other variables based on site-specific geotechnical parameters. Therefore, the geotechnical and foundation design engineers should be made aware of assumptions and limitations associated with the use of this procedure.
This paper is intended to encourage refinement of the procedure by indicating areas where additional research, clarification, and / or corrections may result in better geotechnical and structural designs. This paper addresses the PTI Design Procedure, 3rd Edition. The Foundation Performance Association’s document FPA-SC-05 addresses the PTI Design Procedure, 2nd Edition [12]. The FPA refers to both editions in this paper and describes the version under discussion as the PTI Design Procedure, 2nd Edition or PTI Design Procedure, 3rd Edition. The FPA's recommendations to the PTI Committee are included in italics at the conclusion of each section.

ANSI/SPRI RP-4 2008 Wind Design Standard For Ballasted Single-ply Roofi ng Systems

This standard provides a method of designing wind uplift resistance of ballasted single-ply roofi ng systems. It is intended as a design and installation reference for those individuals who design, specify, and install ballasted single-ply roofi ng systems. It shall be used in conjunction with the installation specifi cations and requirements of the manufacturer of the specifi c products used in the ballasted single-ply roofi ng system.

Fire Resistance Design Manual

This Manual is a convenient and useful specification aid for anyone concerned with the design, construction, or inspection of fire resistive and sound control systems. Design information is quickly and easily determined. Comparison of these characteristics allows the user to be more accurate in meeting design and code requirements. The data provided are especially useful to builders, architects, code officials, fire service, and insurance personnel. When differences occur between provisions of this Manual and the appropriate building code or regulation, including provisions of other standards referenced in the code or regulation, the most stringent provision shall apply. The systems in this Manual utilize gypsum products to provide fire resistance to walls, partitions, floorceilings, roof-ceilings, columns, beams, girders, and trusses. Systems are classified according to their typical uses and their fire-resistance ratings. Walls, partitions, and floor-ceiling systems are further classified by Sound Transmission Class (STC) or Field Sound Transmission Class (FSTC). The Impact Insulation Class (IIC) is included for many wood framed floor-ceiling systems.
