Impact of Footing Model Type on Dynamic Stability in PLAXIS 2D
摘要
Slope stability is a global concern, with researchers proposing various solutions by categorizing the problem based on slope geometry, soil properties, or load types, focusing on static and dynamic stability. This paper uses PLAXIS 2D software to compare the outcomes of using footing as “soil and interface” versus “plates” under dynamic conditions. Researchers have employed different footing properties, resulting in varied inputs in PLAXIS 2D, to examine how model types affect footing settlement. The analysis reveals significant insights into the dynamic response of footings under varying frequencies, highlighting the substantial impact of footing type on structural responses to dynamic loads, particularly on settlement behaviors. Notably, beyond 15 Hz, both the “soil and interfaces” and “plates” models yield similar results, suggesting effective interchangeability for higher frequency analyses. These findings emphasize the critical role of rigorous analysis in ensuring structural stability and performance, offering valuable perspectives on the dynamic behavior of footings across different modeling approaches in PLAXIS.
