Seismic Analysis of Building Structures with Foundation Uplift in Ahmedabad during Republic Day Earthquake
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 4
Abstract
The primary objective of this study is to investigate the effect of foundation flexibility and uplift on the seismic response of building structures located in Ahmedabad, where substantial geotechnical effects occurred during the earthquake. To perform the analysis, the basic data about the soil conditions at the site was collected from subsoil investigation reports that were compiled by various government agencies, local public body and private consultants. The geotechnical model included a nonlinearrepresentation of the soil material below the mat foundation. This foundation model could accommodate both uplift and plastic yielding of the soil material. The superstructurewas idealized as a typical RCC frame structure subjected to the E-W componentof 26January2001 Bhuj earthquake recorded at Ahmedabad station in Gujarat. The authors performed the analysis using the nonlinear computer program using MATLAB.
