Soil–Structure Interaction on Pile Raft Foundation in Multi-Story RC Building with Vertical Irregularity
https://orcid.org/https://orcid.org/0000-0003-0285-7377
Tall buildings are normally supported on certain kind of piled foundation that is exposed to a mixture of vertical, horizontal, and overturning forces. Combination of the pile raft foundation may be a telling sort of foundation system for skyscraper as a result of the raft which is in a position to provide an inexpensive rate of each unwieldiness and load resistance. Now in practice, all the foundation of high-rise building are design as a fixed base, i.e., the relative behavior of soil and foundation are not to be considered. In this paper, soil–structure interaction effect is considered in pile raft foundation of a multi-story building. The G+21 multi-story building is analyzed in software ETABS 2016, and SSI is carried out in PLAXIS 3D. Here, vertical irregularities are taken in the modeling of G+21 story RC MRF building. The seismic analysis of the model is carried under the three different types of analysis methods, i.e., response spectrum (RS), equivalent static load (ESL), and time history (TH) analysis suit to Bhuj time history record which is used for analysis of the moment resistant frame (MRF) reinforced concrete (RC) building. The parameters being used for the comparative study of soil–structure interaction (SSI) are base shear, story drift, and story displacement. Numerical results acquired using SSI model situations are matched to those equivalent to fixed-base situations. The present study shows that the effects of soft soil deposit might be adverse to the earth vibration reaction of the building and avoiding SSI in the evaluation might be prime to unsafe design.
