Numerical Analysis of Seismic Pounding between Adjacent Buildings Accounting for SSI

The structural pounding caused by an earthquake may damage structures and lead to their collapse. This study is focused on the between two adjacent asymmetric with different dynamic properties resting surface of elastic half-space. An exploration relationship effects seismic analysis impact response torsional buildings under SSI has been presented. In this paper, authors have proposed a procedure for analyzing subjected effects, considering systems multiple degrees freedom modal equations motion four types soil. All calculations performed based fourth-order Runge–Kutta method. novelty present related fact that rigorous approximate methods are used examine simultaneously. As result, these thoroughly investigated both results compared. show method produces slightly from those obtained direct integration in case small due increase force. efficiency also validated using numerical examples.
