Abstract
An approximate analytical approach is modified and applied for the study of shallow-buried reinforced concrete arches under severe dynamic loads. The approach contains a closed form solution for wave propagation in soil, transfer functions for simulation of soil-structure interaction, and a layered beam finite element for representing the structure. Several modifications were incorporated in the original approach, for improving the applied loads and for insuring cross-sectional equilibrium in the analysis. The approach has been used for the investigation of four structures that were tested previously by other researchers, and the numerical results were compared with experimental data and corresponding solutions from advanced numerical codes. The results represented reasonably well the general behavior of the structures under consideration, but several serious limitations of the proposed approach were noted. The comparison between experimental and numerical results provided useful observations on the effectiveness of this approach, and recommendations were presented for future applications.
