Determination and Verification of the main Dynamic Characteristics of a Spatially Large Structure Using the Basic Records Combination Method

The aim of the paper is to present some methodological aspects regarding the determination of the vibration eigenmodes of a spatially large, symmetric structure and afterwards to show the obtained results for a spectral analysis of the ground motion in the horizontal plane, corresponding to stea...
