Influence Of Osmotic Suction On The Swell And Compression Behaviour Of Compacted Expansive Clays
(2008-11-03)
Total suction of unsaturated soils is contributed by matric and osmotic suctions.
Matric suction arises from capillary actions in the soil structure and varies with changes in moisture content of the soil. Pore fluid ...
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 ...
Numerical Analysis Of Large Size Horizontal Strip Anchors
(Indian Institute of Science, 2006-03-23)
Structures like transmission towers, tele-communication masts, dry-docks, tall chimneys, tunnels and burried pipelines under water etc are subjected to considerable uplift forces. The net effect of external loading on the ...
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 ...
Novel Sub-Optimal And Particle Filtering Strategies For Identification Of Nonlinear Structural Dynamical Systems
(2009-09-15)
Development of dynamic state estimation techniques and their applications in problems of identification in structural engineering have been taken up. The thrust of the study has been the identification of structural systems ...
Fracture Of Plain Concrete Beams Via Fractals
(2009-09-02)
The quantitative description of rough fracture surfaces of concrete has been an important challenge for many years. Looking at the fracture surface of a concrete specimen, one realizes that the self-affine geometry of crack ...
Studies On Shear Bond Strength - Masonry Compressive Strength Relationship And Finite Element Model For Prediction Of Masonry Compressive Strength
(2009-04-16)
Masonry is a layered composite consisting of mortar and the masonry unit. Perfect bond between the masonry unit and the mortar is essential for the masonry to perform as one single entity in order to resist the stresses ...
Localization Induced Base Isolation In Fractionally And Hysteretically Damped Nonlinear Systems
(2009-08-04)
This Thesis comprises of two parts containing similar studies of Nonlinear Localization induced Base Isolation of structural systems. The present method of base isolation,like other nonlinear vibration isolation methods, ...
Stochastic Analysis Of Flow And Solute Transport In Heterogeneous Porous Media Using Perturbation Approach
(2009-04-16)
Analysis of flow and solute transport problem in porous media are affected by uncertainty inbuilt both in boundary conditions and spatial variability in system parameters. The experimental investigation reveals that the ...
Vibration Analysis Of Structures Built Up Of Randomly Inhomogeneous Curved And Straight Beams Using Stochastic Dynamic Stiffness Matrix Method
(Indian Institute of Science, 2006-07-19)
Uncertainties in load and system properties play a significant role in reliability analysis of vibrating structural systems. The subject of random vibrations has evolved over the last few decades to deal with uncertainties ...
