Performance evaluation of a nonlinear Winkler-based shallow foundation model using centrifuge test results
- P. Raychowdhury, T. Hutchinson
- Engineering
- 25 April 2009
When a structure supported on shallow foundations is subjected to inertial loading due to earthquake motions, the foundation may undergo sliding, settling and rocking movements. Even if the capacity… Expand
Nonlinear Winkler-based shallow foundation model for performance assessment of seismically loaded structures
- P. Raychowdhury
- Engineering
- 2008
When a structure supported on shallow foundations is subjected to inertial loading due to earthquake ground motion, the foundation may undergo sliding, settling and rocking movements. If the capacity… Expand

Seismic response of low-rise steel moment-resisting frame (SMRF) buildings incorporating nonlinear soil–structure interaction (SSI)
- P. Raychowdhury
- Engineering
- 1 March 2011
Abstract Nonlinear behavior at the soil–foundation interface due to mobilization of the ultimate capacity and the associated energy dissipation, particularly in an intense earthquake event, may be… Expand
Nonlinear Material Models for Winkler-based Shallow Foundation Response Evaluation
- P. Raychowdhury, T. Hutchinson
- Engineering
- 7 March 2008
When a foundation is subjected to earthquake ground motions, its slid- ing, settling and rocking movements can provide a mechanism for dissipating energy at the soil-structure interface and thus… Expand
Sensitivity of Shallow Foundation Response to Model Input Parameters
- P. Raychowdhury, T. Hutchinson
- Engineering
- 12 February 2010
From a predictive point of view, it is desirable to characterize the effect of varying model input parameters on the seismic response of soil-foundation systems. In this paper, this issue is studied… Expand
Seismic response analysis of a nuclear reactor structure considering nonlinear soil-structure interaction
- L. Bhaumik, P. Raychowdhury
- Engineering
- 1 December 2013
Abstract This study focuses on the seismic response analysis of an internal shearwall of a typical Indian reactor resting on a medium dense sandy silty soil, incorporating the nonlinear behavior of… Expand
Seismic response of nonstructural components supported by a 4-story SMRF: Effect of nonlinear soil–structure interaction
- P. Raychowdhury, Samit Ray-Chaudhuri
- Engineering
- 1 August 2015
Abstract Previous studies have demonstrated that nonlinear material behavior of a building may lead to an increased seismic response of supported nonstructural components in comparison with the case… Expand
CENTRIFUGE TESTING OF COMBINED FRAME-WALL-FOUNDATION STRUCTURAL SYSTEMS
Numerous existing low-ductility reinforced-concrete (R/C) buildings are commonly retrofit with an additional shear wall to withstand seismically generated lateral forces. To investigate the seismic… Expand

Zonai harmonic functions from two dimensional analogs of jacobi polynomials
- J. Boyd, P. Raychowdhury
- Mathematics
- 1983
The Class I orthogonal polynomials in the complex variables z and are reviewed [7]. These polynomials are two dimensional analogs of the Jacobi polynomials and are orthogonal on the unit disk with… Expand
EVALUATION OF THE SEISMIC PERFORMANCE OF COMBINED FRAME-WALL-FOUNDATION STRUCTURAL SYSTEMS THROUGH CENTRIFUGE TESTING
Numerous existing low-ductility reinforced-concrete (R/C) buildings are commonly retrofit with an additional shear wall to withstand seismically generated lateral forces. For the retrofit structure,… Expand
