| Abstract: | The influence of insulating a structure with a soft first storey (horizontally elastic or elastoplastic or horizontally and vertically elastic) is investigated for horizontally propagating waves. A comprehensive parametric study for a simple structure excited by SH- and R-waves is performed. A reactor building is examined for a horizontally propagating historic earthquake. Compared to a conventional structure, travelling-wave effects become more important for R-waves in a structure with a horizontal soft first storey. For SH-waves, the opposite applies. |
