How to Tackle AAR in Dams

How to Tackle AAR in Dams

Eligible for 2 PDHs

Professor Victor Saouma will answer the following questions in this webinar for Engineers/Managers confronting AAR in an existing dam:

- What is the State of the Art (as opposed to State of the Practice) in AAR dam investigation?

- Are there innovative laboratory tools for AAR?

- What should a FEA entail?

The presenter has been involved in AAR research since 2002, has extensively published on this and related (cracking) topics, has conducted major research programs on AAR for the Tokyo Electric Power Company, the Nuclear Regulatory Commission, and the Bureau of Reclamation Engineers/Managers confronting AAR in an existing dam.

Objectives:

Fundamentals

1. Clarify the role of time, temperature, confinement, concrete mixes and RH in the kinetics of the reaction

2. Describe the consequences of AAR at the micro (swelling, cracking, deterioration) and macro (structural cracking)

3. Monitoring: beyond pendulum, what should be recorded.

Testing

4. Testing particular to AAR (expansion, deterioration)

5. How to analyze test data to attempt prediction of future expansion 

6. 3D Mapping of expansion

Finite Element Analysis

7. Identification of clear, reasonable, and achievable objectives before analysis

8. Must have capabilities in the code (importance of validation)

9. Data collection 

10. Results interpretation

11. Back-calculation of AAR expansion characteristics from pendulum recordings and FEA

12. Connection of past and future expansion

13. Prediction of future expansion/damage and probabilistic risk assessment (i.e. shall we wait for decommission)
