Building with Underground Storey with Variations in Soil Subgrade Modulus
Chaitanya Patel ,  Noopur Shah
This paper studies the seismic behavior of reinforced concrete buildings with multiple underground stories. While current researches mainly aims at understanding the effects of variation in soil subgrade modulus, this study has the ultimate goal of finding appropriate recommendations concerning the inclusion of underground stories in the model for seismic analysis. To achieve this objective, the methodology involves the computer modelling by two alternate approaches, namely, building frame with fixed supports, building frame with supports accounting for soil-flexibility using STAAD.Pro. A comparison of the displacements of the frame and time period of the whole structure is done.
Keywords- Soil subgrade modulus, Winkler Hypothesis, STAAD.Pro, Frame structure with basement floor.
