抄録

The purpose of this paper is to present the method to get a lower bound intensity of harmonic excitation easily, in which geometric non-linearity does not appear, for arch structures subjected to horizontal harmonic excitations. Ordinally, to get the intensity, many numerical calculations are executed. But this present method does not need such calculations. The intensity value can be predicted by coefficients of geometrical non-linear governing equations of the system. This paper shows the way to make the governing equations and the equation of lower bound intensity.
