Hadjian, A H

A method is described for selecting a composite section to replace the columns presently used in reinforced-concrete turbine-generator pedestals. The motivation of this work comes from the desirability of providing added space under pedestal decks without changing the static and dynamic characteristics of presently built pedestals. The latter concern stems from the fact that American turbine and generator manufacturers are reluctant to install their machines on very flexible pedestals and also from the fact that for nuclear power plant pedestals, large displacements during postulated seismic events create difficult design problems for interconnected pipe-lines and electrical conduits. Minimization of these displacements is contrary to the basic principle of more flexible pedestals. It is shown that large reductions in column areas can be achieved.
