WebThese braces provide a supplemental path for the earthquake-induced lateral loads and thus enhance the seismic behavior of the frame by adding energy dissipation capacity and, in some cases, stiffness to the bare frame. Consequently, this retrofitting technique leads to reduction in seismic losses in case of a future earthquake event. WebJun 30, 2024 · The earth dam analysis under the strong seismic load like a destructive earthquake is one of the major topics with respect to the dynamical assessment. Damage control and the structural behaviour during an earthquake is a very important issue for an earthen dam. In this study, a comprehensive review is presented based on literature for …
