Formation of PCIPCI was originated by 6 Florida companiesFounded in 1954Director - Martin P. KornPresident - Douglas ConeInitially consisted of 6 plants and has grown to 278 plants currently

Brief introduction of how PCI was formed.

Goal of PCIDevelop a standard practice

What is the reason of a trade association

The graphic image represents moved from an un-coordinated group to a coordinated more coordinate or standard approach to using a precast solution. With the advent of PCI there became a standard approach to the use of precast prestressed concrete. Although not in the same fashion as the Steel industry the end user could be assured of the design approach, production quality and erection of the structure.

Driving factors for the need to create handbook

Main reasons for the industry to create a design handbook Initiate a Standard Approach to DesignInform owners, architects, and engineers of the application of precast concreteCreate a design aid to assist engineers with precast concrete designCreate a document for precast concrete specifications

Basis of the 1st edition.

The book was to give designers information regarding a wide range and variety of products. The information would be used to estimate design, and size all the necessary members for a precast / prestressed system.

Reasons for creating a 6th Edition

As the concrete design code and building codes are update so is the PCI design handbook. The ACI design code is on a 6 year cycle, IBC is on a 6 year cycle and the ASCE7 is on a 4 year cycle. In addition to design codes being update research in the fields of seismic, flexure, torsion and other important topics prompt revisions. These revisions create additional ductility, increase capacity or long span of the building systems and its components.

Review ProcessHandbook CommitteeIndustry Producer Engineers, Industry Engineering Consultants, and AcademiaTechnical Activities Committee (TAC)Industry Producer Engineers, Industry Engineering Consultants, and AcademiaBlue Ribbon Review CommitteeIndustry Producer Engineers, Industry Engineering Consultants, and Academia

How the handbook committee operates and review process

The Handbook Committee is made of producers, academics and industry consultants. These individuals design or teach the design of precast prestressed concrete on a daily basis. The book is broken into chapter sub-committees and assigned a chapter chairperson. The global changes of the book are well established design code, format etc and then the each sub-committee applies the changes to the examples, theory and references. The book is approved through a Ballot process where the entire committee reviews every chapter and votes. Finally an independent group, Blue Ribbon Review Committee is established to give the entire book a review. The BRC is made of producers, academics and industry consultants

Notable ModificationsCh. 2, Preliminary DesignUpgraded to reflect ACI 318-02 load factorsCh. 3, Analysis and DesignComplete revision due to the introduction of IBC and modification to ASCE codesExamples revised to match code

Modifications

The design tables are updated for revised load and resistance factors. 15ft wide double tee was added. Chapter 3 was completely re-written to reflect the latest research and adoption of IBC 2003. This chapter is a brief introduction to Seismic Design and the details of Seismic Design can be found in the Seismic Design Manual.

Notable ModificationsCh. 4, Component DesignFlexure and shear upgraded to reflect ACI 318-02Torsion returns to 4th edition methodsChanges regarding stress limits

Modifications

The torsion section from the 4th edition was re introduced in the 6th Edition and has been adopted by ACI. The original reference document is10. Zia, Paul and McGee, W. D., Torsion Design of Prestressed Concrete, PCI JOURNAL, V. 19, No. 2, March-April 1974. The revised Reference Document is 11. Zia, Paul and Hsu, T.C., Design for Torsion and Shear in Prestressed Concrete, Preprint 3424, American Society of Civil Engineers, October, 1978. Reprinted in revised form in PCI JOURNAL, V. 49, No. 3, May-June 2004.

Notable ModificationsCh. 6, Connection DesignNew method to design headed studsUpdated connection designLimit State Weld Procedure Presented

Notable ModificationsCh. 9, Thermal, Acoustical, fire and other considerationsSandwich panel research addedFire resistance added to reflect current codeVibration has been rewritingCracking repair and maintenance has been rewritten

Modifications

The vibration section was completely re-written to reflect the industry standard practice. And example a survey was done for the bleacher section to determine acceptable design frequencies and design spans for square and tapered bays. Sandwich wall panel section update on recent research at Lehigh University.

Notable ModificationsCh. 10, Specifications and Standard PracticesCreated a computerized specification.Created a Standard of Practice

Modifications

Removed guide specifications since most design offices have computerized specification. The standard of practice demonstrates where PCI deviates from ACI. It has been republished as a self contained document and can be ordered from PCI. The standard practice and specification are on the CD enclosed on the back cover of the handbook.
