In fairness to the engineers behind the Tacoma Narrows bridge, I haven't seen anything which suggested they didn't know what they were doing. Everything I've seen stated that the resonance which built up due to wind was unprecedented in the Civil Engineering world. It had simply never been encountered or even considered before. According to Wikipedia, the designer of the TN bridge, Leon Moisseiff, was also a major contributor to the engineering of the Golden Gate Bridge. So "Galloping Gertie" is not so much about amateurism, but unforeseen consequences. Of course, most of us are familiar with *those*, too.... -- Ben _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
