Identification Tools For Smeared Damage With Application To Reinforced Concrete Structural Elements
(2011-01-10)Countries world-over have thousands of critical structures and bridges which have been built decades back when strength-based designs were the order of the day. Over the years, magnitude and frequency of loadings on these ... -
Stabilised Rammed Earth For Walls : Materials, Compressive Strength And Elastic Properties
(2011-01-10)Rammed earth is a technique of forming in-situ structural wall elements using rigid formwork. Advantages of rammed earth walls include flexibility in plan form, scope for adjusting strength and wall thickness, variety of ... -
Static And Dynamic Behaviour Of Cement Stabilised Rammed Earth Panels And Building Models
(2011-01-10)Rammed earth is one of the earliest building materials used for structural walls. Stabilised rammed earth is a variant of traditional or pure rammed earth that involves addition of a small amount of cement to improve ... -
The Effect Of Interference Of Strip Foundations And Anchors On Their Ultimate Bearing Capacity And Elastic Settlement
(2011-01-10)Due to close proximity of different civil engineering structures, the ultimate bearing capacity and failure pattern of adjoining footings/anchors are often influenced by their mutual interference. The present thesis is an ... -
Analysis Of Precipitation Controls On Hydrochemistry Of A Groundwater System : Application To Upper Cauvery Basin : South India
(2011-01-10)Groundwater chemistry is a function of recharge and the input chemistry of the rain, which gets transformed as it moves through the soil matrix. Apart from mineral transformations, anthropogenic activities are other external ... -
Fine-Scale Structure Of Diurnal Variations Of Indian Monsoon Rainfall : Observational Analysis And Numerical Modeling
(2010-12-31)In the current study, we have presented a systematic analysis of the diurnal cycle of rainfall over the Indian region using satellite observations, and evaluated the ability of the Weather Research and Forecasting Model ... -
Impact Of Dynamical Core And Diurnal Atmosphere Occean Coupling On Simulation Of Tropical Rainfall In CAM 3.1, AGCM
(2010-12-30)In first part of the study we discuss impact of dynamical core in simulation of tropical rainfall. Over years many new dynamical cores have been developed for atmospheric models to increase efficiency and reduce numerical ... -
Particle Dynamics In A Turbulent Particle-Gas Suspension At High Stokes Number
(2010-12-08)Particle laden turbulent flows find applications in many industrial processes such as energy conversion, air pollution control etc. In these types of flows, there are strong coupling between the turbulent fluctuations in ... -
Time Dependent Deformations in Normal And Heavy Density Concrete
(2010-12-08)Time dependent deformations in concrete, both creep and shrinkage, play a critical role in prestressed concrete structures, such as bridge girders, nuclear containment vessels, etc. These strains result in lossess, through ... -
Biennial Oscillation Of Indian Summer Monsoon And Global Surface Climate In The Present Decade
(2010-12-08)The ENSO-monsoon system is known to have a biennial component. Here we show using high resolution satellite data, mainly daily rainfall and sea surface temperature (SST) from the Tropical Rainfall Measuring Mission (TRMM), ... -
Experimental And Theoretical Studies In Fatigue Damage Modeling
(2010-12-07)This thesis has two parts. In the first part, we use the results of new fatigue experiments conducted with variable load levels as well as variable stress ratios to critically assess three (two old and one relatively ... -
A Study Of Four Problems In Nonlinear Vibrations via The Method Of Multiple Scales
(2010-12-03)This thesis involves the study of four problems in the area of nonlinear vibrations, using the asymptotic method of multiple scales(MMS). Accordingly, it consists of four sequentially arranged parts. In the first part ... -
Experimental Investigation Of Hypersonic Boundary Layer Modifications Due To Heat Addition And Enthalpy Variation Over A Cone Cylinder Configuration
(2010-12-01)Despite years of research in high speed boundary layer flow, there is still a need for insightful experiments to realize key features of the flow like boundary layer response to different conditions and related transition ... -
