Major concrete infrastructures (such as dams, nuclear power plants, offshore structures) play a crucial role in societal needs. As such, they are (or should be!) continuously scrutinized, analyzed and diagnosed for possible damage/failure which could be catastrophic in terms of human loss and property damage.
This talk will address two major safety concerns: aging through Alkali Aggregate Reaction, and shaking by a strong ground excitation. In both cases cracking is nearly inevitable.
Unfortunately, whereas we are well equipped to design those new structures (usually linear elastic), we are not yet well equipped to properly assess their safety (typically, this will require sophisticated nonlinear analyses rooted in advanced testing and proper constitutive models).
This talk will show how innovative laboratory tests can lead to numerical models, and finally to practical investigation within the context of a nonlinear analysis. All examples will be drawn from the speaker own experience in research or consulting.
About the speaker :
Victor Saouma is a Professor of Civil Engineering at the University of Colorado in Boulder. He is the president of FramCoS and Chair of RILEM Committee on Prognosis of deterioration and loss of serviceability in structures affected by alkali-silica reactions. His current work is funded by both the Oak Ridge National Laboratory and the Nuclear Regulatory Commission.
