| Abstract | Structure is conventionally analyzed under fixed base assumption without considering soilstructure interaction (SSI) because it provides a conservative design. However, recent studies show that conventional fixed base analysis may underestimates the seismic response and this may lead to unsafe design. The actual responses of the structure have not been known before the complete analysis of soil-structure interaction (SSI) is perfo1med. In this study, the effects of SSI are analyzed for typical high-rise building in Jakarta, Indonesia. Nonlinear dynamic time history analyses are performed for 3 different foundation models (fixed, pile, and raft foundation) to asses the effects of SSI on seismic response of the buildings for different foundation types. The inclusion of seismic SSI is modeled through dynamic beam on nonlinear Winkler foundation method. The nonlinear behavior of the structure is modeled using lumped plasticity model. The nonlinear response history analysis (NLRHA) of the structure is performed under maximum considered earthquake (MCE) level for Jakarta city. The scaled strong motion records from 5 famous earthquakes around the world and 2 earthquakes from inside Indonesia are used to cover the wide variability of the ea11hquake characteristics. The results show that the effects of SSI in term of peak story shear and moment had been reduced when considering SSI. However, in some part of the building the response from the SSI analysis gives a larger response compared to the non-SSI analysis. Therefore, the effects of SSI on this building are not always beneficial and may be detrimental in some part of the building. The detrimental effects of SSI are also identified from interstory drift response. The consideration of SSI has increased the plastic def01mation of the building. The influences of foundation types on the force seismic response are only found at the podium level while the force seismic response above the podium level remains no influences. At the podium level, the force seismic response provided from pile foundation is larger than the force seismic response provided from raft foundation. |
