Yes, Nadine, too much flexibility is definitely a bad thing. I believe that was the case with the famed Tacoma Narrows Bridge Collapse, I think the consensus (if there is one) was that the bridge's long stiffening girder was too long and too flexible. See link.

Earthquakes have for long been the cause of major destruction of infrastructure and these stronger materials should not only be used in bridges but everything else. Being able to have an earthquake that will only shake the ground and that's it is something that would come as a blessing since it is practically impossible to stop the earthquakes. What I am more worried about is the costs of the materials. The nickel titanium is not something that is as abundant as iron. This is a good idea but the sources of these minerals should also be considered. As far as the cost is concerned I do not thing it would be a bad idea since they would also last.

Yes, AandY, your comments and concerns echo what a lot of our readers think about this. While most agree it's a good step forward to strengthen structures against damage from quakes, they worry about the potential expense.

I remember traveling to Boston, for the first time, and the Big Dig was in process. What a complete mess! My fellow editor, an excellent driver and navigator who did all the driving and had gone to the same show in the same location a zillion times before, got lost, for the first time ever, on the way from the airport.

Correct scale?

Aside from the potentially larger cost differential, I also wonder if the simulations and other testing the researchers did adequately took into account the scale involved of the actual columns. Were the models full scale or smaller?

Good question, Ann. I'd have to go back to my notes to see about the scale of the models. The closer to real-life deployment, the better, of course.

Thanks for the comment, AandY. I think it points to the opinion of the researchers, which expect that there will be other benefits that outweigh the increased costs of the material.
