Inverse Sensitivity Methods In Linear Structural Damage Detection Using Vibration Data
(2009-06-29)
The thesis addresses the problem of structural damage detection using inverse sensitivity based methods. The focus here is on characterization with regard to identification, location, and, quantification of structural ...
Grey Optimization For Uncertainty Modeling In Water Resources Systems
(2009-07-08)
In this study, methodologies for modeling grey uncertainty in water resources systems are developed, specifically for the problems in two identified areas in water resources: waste load allocation in streams and floodplain ...
Hydrologic Impacts Of Climate Change : Uncertainty Modeling
(2009-07-02)
General Circulation Models (GCMs) are tools designed to simulate time series of climate variables globally, accounting for effects of greenhouse gases in the atmosphere. They attempt to represent the physical processes in ...
Strength And Deformation Behaviour Of Jointed Rocks : An Equivalent Continuum Model
(2009-06-30)
Most rock masses encountered in civil and mining engineering projects contain pre-existing discontinuities. These discontinuities weaken the rock masses to an extent, which depends very much on the size of engineering ...
A Study On Inelastic Response Of Multi-Storey Buildings To Near-field Ground Motions
(2009-07-21)
With the advancement in knowledge of inelastic response of structures, the design and construction practices of reinforced concrete buildings have been changing worldwide. Most of the codes are incorporating the near-fault ...
Methods For Forward And Inverse Problems In Nonlinear And Stochastic Structural Dynamics
(2009-09-03)
A main thrust of this thesis is to develop and explore linearization-based numeric-analytic integration techniques in the context of stochastically driven nonlinear oscillators of relevance in structural dynamics. ...
Modelling Of Single And Multiple Recharge Wells In Layered Aquifers
(2009-05-06)
Artificial recharge and rainwater harvesting methods are being applied for mitigating effects of groundwater depletions in severe over-drafting urban and rural situations. When the aquifer to be recharged is situated at ...
Geotechnical Site Characterization And Liquefaction Evaluation Using Intelligent Models
(2009-12-09)
Site characterization is an important task in Geotechnical Engineering. In situ tests based on standard penetration test (SPT), cone penetration test (CPT) and shear wave velocity survey are popular among geotechnical ...
