This year’s Annual Meeting has shown a growth in workshops (67). It is expected to have
more than 9300.
Appreciate timely review of papers: 2600 papers were submitted and peer reviewed in 2005
compared to 2500 papers in 2004 and only 2000 papers four years ago. 62% of the papers
were presented at the 2005 TRB meeting. Also, TRB has 60 meet the authors sessions.
Attendance should be about equal to or maybe even greater than last years however,
attendance on Sunday is heavy.
There is more emphasis on moving towards holding poster sessions due to room availability.
Out of the presentations, 48% were papers and 15% in design group.
Two sessions per committee with an exception for a third session. Also about 100-150
practical papers with implemental results are included in each CD.
The 6th International Bridge Engineering Conference will be held at the Westin Copley Place,
Boston, MA; July 17-20, 2005. Flyers were passed to members. The Conference is
sponsored by the Structures Section

11. AFF40-1, NDE SUBCOMMITTEE REPORT
Subcommittee Chair Glenn Washer reported on the 2004 SMT Conference sponsored by the
American Society on Non-Destructive testing (ASNT) and that was held in Buffalo, NY, 2004. He
mentioned that the Conference had about 15-20 exhibitors, 25 DOT, and 65 papers in proceedings
which were also available on CD ROMs. He asked the chair about future sponsorship from TRB and
Committee AFF40. A motion was proposed by Michael Chajes to provide sponsorship to the “NDE
for Civil Engineering” conference by TRB and Subcommittee on NDE for Civil Engineering ,
Motion was seconded by Steve Chase and passed unanimously.

COMMITTEE AFF40
DYNAMICS AND FIELD TESTING OF BRIDGES
Chair Washer also announced that ASNT is revising their handbook on ultrasonic testing and asked
members to provide him with any info related to that document to be developed in the next 12
months
He also noted that the Subcommittee on NDE will meet on Wednesday. Chair Walther asked Glen
Washer for a copy of roster list of subcommittee.
12. SUBCOMMITTEE A, ON-GOING BRIDGE PROJECTS AND COMMITTEE MEETING
PRESENTATIONS
Robert Sweeny organized the presentations for the on-going projects and the overall presentation time
was limited to 1.5 hour. Preference was given for a period of 5 minutes for each presentation. Jeff
Shultz will help Bob Sweeny in organizing the 2006 On-Going Project presentations.
50-year Anniversary of Interstate Highway System
Chair mentioned that each committee will identify a speaker who is willing to prepare a paper and
present it. No other session will be held during that time and expects 200 people in attendance. Chair
also noted that there is a need to think about an individual who might be a member of the committee.
Steve Chase was asked to be that speaker. Steve Chase accepted and noted that he will need the
collective thoughts of the committee to have ownership of the paper and that maybe Ivan Weiss’s
paper can be a starting point. Chair will prepare an abstract for the session. Ian Friedland suggested a
theme for the paper: “50-year design, 50-year life” and that previous designs are not a disaster and
now bridge testing helped prove that bridges last longer than the 50-year design life. The Chair
proposed to have typical historic photos for the sessions to be posted on the wall of the room and will
need a volunteer to collect for historic photographs. David Barret and Bob Sweeney will handle the
boards and photos with committee name and scope and maybe end up with a wall of photos.
13. SUBCOMMITTEE B - PRESENTATIONS
2006 Proposed Sessions for TRB Meetings
Committee members were asked by Chair to present new session ideas for 2006. AFF40 has 8
committees and each committee will have 2 sessions. Cosponsoring sessions with other committees
will not take away sessions. Chair also noted that the committee should try to fill two sessions and
then co-sponsor a third session with other committees.
Suggested Sessions Titles for 2006:
1- Monitoring and Testing of FRP Structures, to be co-sponsored by AFF10.
2- Hot Topic Session (suggestion: Inspection of post-tensioned ducts”)
3- or a session on Bridge Testing
Glenn Washer suggested a workshop on durability issues and inspection. Jeff Shultz and Michael
Chajes prefers to keep the session more broad along the lines of “Instrumentation & Emerging
Technologies”. It was agreed to create a call to papers, one on Field testing and one on NDE with
bullets on various topics needed for the sessions. Chair will submit the titles while Glenn Washer
will do the NDE call for papers by March 31st and Mark Bowmen will do the call for papers for the
session on Field Testing.
A discussion on a title for the workshop was pursued afterwards. Ian Friedland suggested to check a
FHWA report on inspection of ducts and to check with Ben Tang. Chair asked for a volunteer to lead
the workshop and coordinate with FHWA. Larry Olson volunteered and he will work with Hamid
Ghassemi on “Inspection and Evaluation of Cable Supported Bridges”. Khaled Mahmoud will also

COMMITTEE AFF40
DYNAMICS AND FIELD TESTING OF BRIDGES
assist Larry Olson in his efforts. To defray the cost of workshop, all the authors were asked to prepare
a paper and produce a CD with the paper and handbook. FHWA supported the cost of the production.
14. SUBCOMMITTEE C - RESEARCH NEEDS
Chair presented the current research statement on “Remote Structure Monitoring Techniques for
Health Monitoring” did not make it and that the committee should not re-submit current statements.
Chair asked Steve Chase to present new Statements to 2006. Steve Chase mentioned the statement on
the “Development of guidelines and example applications for the integration of field testing with
bridges management” and explained that testing of bridges can be used for more than load rating and
it can be used for making better decisions. He suggested to post the statement on the website. Chair
asked members to also submit more statements (about 3 to 4) and to have them ranked by the
committee.
Chair also announced a NCHRP synthesis through the survey related to fracture critical bridges to
fine tune fatigue calculation through field testing. Chair asked Robert O’Connor to send a copy of the
synthesis for review by the committee.
New Suggested Topics for Research Statements
- Specifications to assess renewing fatigue life of fracture critical bridges
- Development of relationship between out-of-plane distortion and stress concentration
Chair also suggested possible topic for statements:
- Residual Stress Measurement
- Stress concentration Measurement Using Infrared Imaging
- Power scavenging for Long Term Monitoring
- Strategic R&D Plan for AFF40
Chair noted that there is a need for an AASHTO member to submit these statements and to try and get
sponsorship with other committees. He also suggested making a separate document from the minutes
and listing few topics and posting them by March 1st. The Committee will rank 3-4 topics and submit
top one. Steve Chase will continue to serve as a collector of all statements.
Timeline:
- Solicit potential RNS by 31 Jan, 2005.
- Electronic review by 15 Feb, 2005.
- Discussion and vote on 20 Feb, 2005.
- Revise and resubmit to TRB by 1 March, 2005.
15. SUBCOMMITTEE D - TRIENNIAL SELF EVALUATION
Triennial Self Evaluation (2005)
Chair asked members for all their info related to the TSE. He will send an email to remind the
members to get the response by March 1st.
