Adaptive reduced order modeling of dynamical systems through novel a posteriori error estimators : Application to uncertainty quantification
Multi-query problems such as uncertainty quantification, optimization of a dynamical system require solving a governing differential equation at multiple parameter values. Therefore, for large systems, the computational ...
Structural Reliability Estimation Using Markov Chain Splitting and Girsanov’s Transformation Based Methods
The work reported in this thesis is in the area of Monte Carlo simulation based methods for structural reliability estimation with special focus on strategies to reduce sampling variance of the estimator for the probability ...
Subsurface Profiling of Shallow Bedrock Sites by Integrated Approach and Site-specific 2d Site Response Analysis
Estimation of reliable site effects and amplifications are important for seismic design. There are several 1D and 2D large scale site response analyses were reported in the literature and very limited shallow bedrock small ...
Analytical Models For Stress-Strain Response Of Fiber-Reinforced Soil And Municipal Solid Waste
(2011-04-01)
The present thesis proposes model for the analyses of stress-strain response of fiber reinforced soil and municipal solid waste (MSW). The concept of reinforcing soils by introducing tension resisting elements such as ...
Response And Reliability Analyses Of Soil Nail Walls
(2011-04-01)
In the present thesis, studies on the response of soil nail walls subjected to static and seismic conditions using finite element based numerical simulations and the principle of reliability analysis have been performed. ...
Strength and Deformation Behavior of Municipal Solid Waste (MSW) Based on Constitutive Modeling Approach
(2018-04-11)
The geotechnical properties of municipal solid waste (MSW) such as compressibility, shear strength and stiffness are of prime importance in design and construction of landfills. However, it is not well clear how the ...
Probabilisltic Analysis of Engineering Response of Fiber Reinforced Soils
(2018-04-03)
The concept of reinforcement was developed in late 20th century and since then till the recent past there are many works carried out on the effect of fibers in imparting strength and stiffness to the soil. Experimental ...
Liquefaction Resistance and Cyclic Response of Air - Injected Desaturated Clean Sandy Soil: Experimental and Numerical Investigations
Liquefaction has been one of the major concerns in the field of geotechnical earthquake engineering. Various mitigation techniques such as vibroflotation, deep dynamic compaction, explosive compaction, grouting, deep soil ...
Reliability Based Design Methods Of Pile Foundations Under Static And Seismic Loads
(2010-09-03)
The properties of natural soil are inherently variable and influence design decisions in geotechnical engineering. Apart from the inherent variability of the soil, the variability may arise due to measurement of soil ...
