Performance analysis of base-isolated structures in mitigating underground blast-induced ground motion effects: A parametric study.

This study delves into mitigating ground motion induced by underground blasts on superstructures. A parametric analysis is conducted to assess the performance of base isolated structures under different blast scenarios. The analysis is conducted using Newmark's time step integration method, and the absolute acceleration of the structure and displacement of the isolator bearing are calculated to evaluate the response.
