NISA is used extensively to measure forces induced in structures by earthquake, study the effects on the supporting soil, and look at soil-structure and structure-soil-structure interactions. NISA is used for the estimation of natural frequencies for simple to complex systems and valuation of dynamic response under the influence of various loads such as time varying, harmonic, shock and probabilistic. Seismic analysis is one of the most popular applications of NISA.
