Numerical Evaluation of Multi-Storied Building with Floating Foundation under Dynamic Loading

S. Syed Ibrahim, E. Alexandar

Abstract


Unexpected earthquakes have frequently been occurring all over the earth crest that led to destroy structural/nonstructural buildings/elements in addition to human lives on a large scale. To address the above such losses due to natural phenomenon, several techniques have introduced by various researchers such as variable stiffness system (VSM), ribbed bracing system (RBS), base isolation techniques (BIT), active tuned mass damper (ATMD), and etc., which were exploded asunder on the basis of earthquake-resistant structural design. This paper proposes a technique in which the effect of the wave action intended to reduce/neglect at foundation level itself by constructing a ball and socket type of joints between column and footing intersections. To recognize the technique, a dynamically responded high-raised building model was developed with pinned supports using STAAD.Pro software and the results were compared with the similar model having conventional (fixed) supports. It was found from the analysis that the flexibility of the structure increased substantially by pinned type of supports when compared to that of a fixed type of supports.
