Abstract

The present paper discusses and proposes the estimation method of the dynamic response of a reticular dome supported by a sub-structure based on push-over analysis considering the effects of the second mode. The investigation shows that in most cases of ordinary reticular domes the sum of the effective masses for the first and second mode is greater than 90% of the total mass even if the effective mass for the first is as small as 30% of the total mass. Under such condition of small effective mass of the first mode the accuracy of the estimation is investigated through comparison between those based the present estimation and the results based on direct dynamic nonlinear response analysis, leading to a conclusion that the present estimation method is fur efficient than that previously proposed by the same authors neglecting the contribution from the second mode.
