Soil-structure interaction study of a mid-rise reinforced concrete building with a rigid and flexible base
Soil-structure interaction study of a mid-rise reinforced concrete building with a rigid and flexible base
This study focuses on examiningthe effects of four different soil typeson the dynamic behavior of a six-story reinforced concrete building frame. The soil profiles, classified as hard (S1), firm (S2), soft (S3), and very soft (S4) according to the Algerian seismic code, are considered. The linear soil-structure system was analyzed with a global method using FLAC2D software. The response of the structure, considering the soil-structure interaction (SSI), was evaluated and compared to that of the fixed base structure. The principal parameters investigated in this paper are (a) top story displacement, (b) base shear, (c) inter-story drifts, (d) instability due to second-order effects, and (e) top story acceleration. Numerical results show that SSI increased all parameters analyzed in this study, and the S4 soil type showed a particularly pronounced increase.
