Geotechnical and earthquake engineering put a great deal of emphasis on slope stability studies under dynamic loads. The input ground motions and the dynamic characteristics of the soil medium greatly influence how slopes respond to seismic waves. The current work investigated the Seismic behavior of a bamboo grid reinforced slope, geogrid reinforced slope, and unreinforced slope, which utilized 2D numerical analyses using the finite element program MIDAS GTS NX (340) 2023 v1.1. For this investigation, Three ground motion records, such as 1940, El Centro Site, 270 Deg, 1971 San Fernando Down, and 1985, Mexico City, Station 1, 180 Deg, are used in the nonlinear time history analysis of the slope. The comparison of lateral displacement, settlement, and developed acceleration results for different slopes.The face of the slope is a more vulnerable zone due to the 1940 El Centro Site, 270 Deg (ground motion − 1), whereas the base of the slope is more vulnerable due to the 1971 San Fernando Down (Ground motion − 2) and the crest of the slope is more vulnerable due to Mexico City, Station 1, 180 Deg (Ground motion − 3). Hence, the reinforcement is more effective for ground motion − 1 and less effective for ground motions 2 and 3. Maximum variation of acceleration, lateral displacement, and settlement are seen up to 5 s in all cases of ground motion. Hence, up to 5 s is crucial for all ground motion. The bamboo grid reinforced slope performed well compared to the geogrid reinforced slope and unreinforced slope regarding lateral displacement and settlement for ground motion − 1.
