Chairman Videla announced the request from TAC about how the committee will consider the inclusion of sustainability in ACI 209 documents. Copies of the following documents were distributed at the meeting: • Agenda for this meeting. • Minutes of the San Antonio, TX Spring 2009 meeting. • Committee Roster (11/09/09) (see Attachment A with corrections). • Update ACI 209.1R-XX (11/6/2009), Committee 209 Web Letter Ballots Results (see

Attachment B). • ACI 209.3R-XX Letter Ballot 11-06-2009, Committee 209 Web Letter Ballots (see

Attachment C). Also the following documents were distributed at the meeting but are not included in the minute: • Update ACI 209.1R-XX - Summary Web Letter Ballots Results (4/9/2008 and 11/6/2009) • ACI 209.3R-XX – Summary Web Letter Ballots Results (10/26/2008 and 11/6/2009) 4. Approval of Minutes from the Spring 2009 Meeting in San Antonio, TX. Chairman Videla asked for review and approval of the minutes. Weiss pointed that on the eighth line under 5.2 Status of ACI 209.3R-XX “Time Dependent Effects in Concrete Structures.” it should read “new Chapter 5” instead of “new Chapter 4.” All members present voted in favor of approving the St. Louis meeting minutes with the change proposed by Weiss. 5. Current Subcommittees Actions Updates. 5.1 Status of ACI 209.1R-05 “Report on Factors Affecting Shrinkage and Creep of

Hardened Concrete.” Chairman Videla informed that in the letter ballot that closed on November 6, 2009, there was one negative vote from Bažant and affirmative votes with comments from Gardner and Roberson. Bažant withdrew its negative. Chairman Videla explains that comment by Gardner on Item 2 is correct, because Figure 3.4 included in ACI209.1R-05 has the “y” axis title changed from the original figure published in the conference proceeding. Harald Muller has provided a copy of the referenced paper and the conference proceedings figure will be included. Comments by Robertson will be incorporated in the text of the report. Therefore, the ACI 209.1R-05 stands as approved. A summary of voting is as follows:

Item No. Affirmative

5.2 Discussion on the Name for the ACI 209.3.R-XX Report Chiorino presented six different options to rename the ACI 209.3R-XX report (see Attachment D). After discussion, Chiorino moved and Nassif seconded to name the report as “Analysis of

of 26

Creep and Shrinkage Effects in Concrete Structures.” Eight members voted affirmative, no negative votes, with one abstention. 5.3 Status of ACI 209.3R-XX “Time Dependent Effects in Concrete Structures.” Chairman Videla informed that in the letter ballot that closed on November 6, 2009, there was one negative vote on Item 7 by Novak referring to “Incomplete (tables are empty),” and one negative vote by Dilger on Item 8, “This Appendix is incomplete.” There were affirmative votes with comments by Dilger and Videla. Therefore, the ACI 209.3R-XX ballot dated 11/6/2009 was approved pending the resolution of the negative votes by Novak and Dilger, and the incorporation of the comments by Dilger and Videla. Chiorino will resolve the negatives to the satisfaction of Novak and Dilger and will incorporate the comments. A summary of voting is as follows:

Item No. Affirmative

Affirmative with

Therefore, the ACI 209.3R-XX stands as approved document pending the resolution of the negative votes of the 10/26/2008 and 11/06/2009 ballots. Bažant commented that the ACI 209.3R-XX is a fine text book, but has not being calibrated with actual measurements of structures deformations. Chiorino will incorporate in the text of the report a statement based in Bažant’s comment. 5.4 Discussion on the Table of Content for the Proposed CD “Alternative Design Aid to

Appendix I of ACI 209.3R-XX. Chiorino presented for discussion the table of content for the CD “Alternative Design Aid to Appendix I of ACI 209.3R-XX.” (see Attachment E). A discussion followed and Chiorino will revise the table of content as discussed. 5.5 Report from the subcommittee on “Statistical Procedures in the Evaluation of Creep

and Shrinkage Prediction Models.” D’Ambrosia informed that there was no meeting of the subcommittee on “Statistical Procedures in the Evaluation of Creep and Shrinkage Prediction Models.”

5.6 Status of ACI 209.4R-XX “Test Methods for Creep and Shrinkage,” Nassif informed of the committee work progress of subcommittee ACI 209.4R-XX. Weiss, Lange and Nassif will submit a complete outline of the proposed report at the meeting during the 2010 Spring Convention in Chicago for committee approval. 6 Other Business No other business. 7 New Business Chiorino informed on the planed 2010 Conference sponsored by the “International Center for Structural Mechanics, CISM” in Venice.

Our analysis of the bridge in Palau showed that the kind of approach described is a fictitious exercise. The objective should be to help engineers to produce more durable designs, which would last 100 year instead of 20. I

challenged Prof. Chiorino to demonstrate how his artificial approach would improve the grossly erroneous predictions for the bridge in Palau as well as the the 4 Japanes bridges I brought to the attention of the committed. There is not a single example of comparison with observations on structures. Without it, it would be irresponsible to issue a report to be followed by practicing engineers. I recommend returning to the original draft of Prof. Dilger.

Description: In this “ACI 209.3R-XX Aug. 31 2009 for Ballot.pdf”, members of ACI 209 are asked to vote only those sections or portions of the document identified as “New edition, to be balloted” since the remaining portions were either already approved in previous ballots or are editorial comments to satisfy comments from previous ballots. Items already approved are indicated in blue and items to be balloted or re-balloted in yellow. That is, in total there are: 1 Item to be re-balloted (Chapter 5) 7 New items to be balloted (Appendixes C, D, F, G, H, I, L). In order to facilitate the task of committee members, a summary of the Ballot situation is given in the attached Table of Contents of ACI 209.3R. Later on the negatives from the two ballots will be solved. It should be mentioned that with respect to the tables of values included in Appendix I, intended as design aids, the alternative of providing a CD containing the program for calculating any desired value of the various coefficients and functions included in the document and of interest for designers, has been analyzed with the TAC representative. According to the response of TAC contact, it should not be a problem having a CD with all information needed for design if previously reviewed and approved by TAC.

ATTACHMENT E

CD PROGRAM Time Dependent Analysis of Concrete Structures

The proposed CD to be associated with ACI 209.3R will contain: 1. INSTRUCTIONS for the use of the program creepanalysis

2. PROGRAM creepanalysis

The program creepanalysis is implemented for the 4 creep and shrinkage prediction models • ACI 209R-92 (ACI Committee 209 1992) (under preparation)

• Bažant-Baweja B3 (Bažant and Baweja 1995, 2000),

• CEB MC90-99 (CEB 1990, 1993a, FIB 1999)

• GL2000 (Gardner and Lockman 2001).

The program creepanalysis contains the recurrent algorithm for the numerical solution of the liear aging integral euation.

3. OUTPUT OF THE PROGRAM creepanalysis

3.1 SHRINKAGE

Diagrams and single values for given time for any choice of influencing parameters 3.2 CREEP

Diagrams or single values for given time for any choice of influencing parameters for: • Compliance function (with conventional subdivision between initial and time-

dependent strain)

• Creep coefficient in coherent connection with a conventionally defined initial strain

• Relaxation function

• Redistribution function

• Ageing coefficient

• Reduced relaxation functions
