The 3rd International Workshop LCC03/IABMAS

Joint Event

Life-Cycle Cost Analysis and Design of Civil Infrastructure Systems

and

fib WG 5.3-1, WG 5.6 / Joint Committee on Structural Safety

Probabilistic Modeling of Deterioration Processes in Concrete Structures

Swiss Federal Institute of Technology - EPFL
Lausanne, Switzerland
March 24-26, 2003

Background and Motivation

The civil infrastructure systems of the world represent a huge investment for both governments and taxpayers. The life cycle benefits of this investment must be maximised to ensure that the needs of our society are optimally met, taking into consideration safety, economy, and sustainability requirements. The Life-Cycle Cost (LCC) analysis and design of civil infrastructure systems plays an important role in maximising these benefits.

With this in mind, it was decided to initiate a series of International Workshops on Life Cycle Cost Analysis and Design of Civil Infrastructure Systems. The First (LCC01) and Second (LCC02) International Workshops on Life-Cycle Cost Analysis and Design of Civil Infrastructure Systems were held in Honolulu, Hawaii, USA, August 7-8, 2000, and Ube, Japan, September 27-29, respectively. The Third International Workshop on Life-Cycle Cost Analysis and Design of Civil Infrastructure Systems (LCC03) to be held in Lausanne, Switzerland, March 25-26, 2003 is the most recent in this series.

In parallel to the initiative of the LCC03 a workshop was planned jointly by the Joint Committee on Structural Safety (JCSS) and Fédération Internationale de Béton (fib). The main objective of this joint workshop was to identify and implement a generally acceptable basis for the probabilistic modeling of deterioration processes in concrete structures. Much important work has already been performed in an effort to achieve this, however, the issue of identifying and implementing a generally acceptable basis for the probabilistic modeling of deterioration processes in concrete structures remains open. This task is essential for the further progress of the work of the fib and for the further development of the JCSS Probabilistic Model Code.

Recognizing the potential synergetic benefits it was decided to merge the two workshops. As a consequence the participation in the workshop will be broader and include all aspects and contributors in the problem area. The forum will thus not only represent a unique scientific, technical, operational and economical expertise in the area of Life Cycle Cost analysis for infra-structure systems but in addition provide a very rare possibility to achieve consensus on basic aspects and principles in the underlying modeling.

Topics

Workshop of fib WG 5.3-1, WG 5.6 and the Joint Committee on Structural Safety

Probabilistic Modeling of Deterioration Processes in Concrete Structures

Models and data for environmental exposure conditions
Models and data for deterioration processes
- chloride ingress/carbonation/freeze-thaw/frost
- corrosion
Aspects of spatial variability
Comparisons between laboratory and field data
Interaction between mechanical loading and environmental influences
Quality of execution
JCSS Probabilistic Model Code for deterioration of concrete structures

The 3rd International Workshop of Life-Cycle Cost Analysis and Design of Civil Infrastructure Systems

General Aspects of Deterioration modelling

Modelling of time evolutionary processes (corrosion, fatigue)
Effect of planned inspections on deterioration models
Relationships between deterioration and structural performance/safety
Reliability of forecasts of future bridge and tunnel condition

Risk based safety evaluation of structures

Acceptable safety (reliability levels)
Low probability – high consequence hazards (natural hazards : earthquakes, flood; man-made hazards: impact, fire, explosion)
Risk ranking
User costs and benefits generated by infrastructure
Vulnerability of structures

Inspection and monitoring

Effect of inspection and monitoring on structural reliability / effectiveness in removing model uncertainties (case studies)
Modelling the quality of inspections
Value of inspection – possible decrease in costs by increasing structural reliability versus cost of inspections or monitoring

Workshop set-up:

each of the above general themes are treated by a Work Group (WG)
each WG chairman (who will be selected at a later date) will prepare in advance a list of specific questions to be discussed within the WG focusing on the following general questions:
- What is state-of-the-art?
- What is the best practice?
- What are the research needs?
- What topics are not relevant?
each WG will have a list of statements / conclusions at the end of the meeting

Presentations and Proceedings:

Participants are encouraged to prepare papers and give presentations (15 minutes)
Papers for the working document must be submitted to the secretariat one month prior to the workshop (February 24, 2003).
All papers will initially be available as preprints that will be distributed to all workshop participants upon arrival at the Workshop. This document will be used as a basis for discussion during the Workshop.
All papers are to have the format suggested by the ASCE as the papers, following a formal review process after the Workshop, will be published in book form by ASCE. Their guidelines are attached as LCCJCSSGuidelines.pdf Otherwise they may be found at www.pubs.asce.org/authors/crinstruct.pdf
The only differences are:
- The section “What to send” should read. The paper, in MS-Word format, must be sent to the LCC and JCCS 2003 Workshop Secretariat in Switzerland by e-mail, Bryan.adey@epfl.ch, or normal mail on a 3.5” DOS formatted diskette, so that it arrives before February 24th, 2003. If sent by air mail please send the envelope so that it arrives by February 24th, 2003 to:
  
  Bryan Adey
  MCS-ENAC-EPFL
  1015 Lausanne
  SWITZERLAND
- The section “Copy right transfer agreement” should contain the additional phrase: Please bring the signed copyright transfer form to the Workshop in March, or send it to the Workshop Secretariat (address indicated above). All copyright transfer agreements will be sent to the ASCE together by the Workshop Secretariat. ASCE Copyright Transfer Agreement
- The section “Camera-Ready Printout” can be ignored, as the Workshop Secretariat will submit the articles together to the ACSE after they are reviewed.
Please submit the papers electronically as Word documents.
Papers should be less than 8 pages, A4.
If it is desired to make any changes to the paper after the workshop, they may be made prior to April 24, 2003. The papers to be considered for review must be submitted to the Workshop Secretariat no later April 24, 2003.
The statements and conclusions from each theme will be published in “Structural Engineering International”, the journal of IABSE.
