Hydrologic Impacts Of Clmate Change : Quantification Of Uncertainties
(2011-02-10)General Circulation Models (GCMs), which are mathematical models based on principles of fluid dynamics, thermodynamics and radiative transfer, are the most reliable tools available for projecting climate change. However, ... -
Non-Linear Finite Element Analysis Using Strain-Space Plasticity Coupled With Damage
(2011-01-27)The Thesis deals with Strain-Space Plasticity and its implementation in Nonlinear Finite Element frame-work coupled with damage. Conventional Stress-Space Plasticity, though very popular amongst commercial nonlinear FEM ... -
Fuzzy Dynamic Wave Models For Flow Routing And Flow Control In Open Channels
(2011-01-10)The dynamic wave model (the complete form of the saint-Venant equations), as applied to flow routing in irrigation canals or flood routing in natural channels, is associated with parameter and model uncertainties. The ... -
Steady State Dynamics Of Systems With Fractional Order Derivative Damping Models
(2011-01-10)Rubber like materials find wide applications in damping treatment of structures, vibration isolations and they appear prominently in the form of hoses in many structures such as aircraft engines. The study reported in this ... -
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 ... -
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 ... -
A Magnesia Based Sustainable Method For De-Fluoridation Of Contaminated Groundwater
(2010-10-14)Groundwater is a major and sometimes lone source of drinking water worldwide. The chemical composition of groundwater is a combined product of the composition of water that enters the aquifer and its reaction with various ... -
Optimum Design Of Retaining Structures Under Static And Seismic Loading : A Reliability Based Approach
(2010-10-14)Design of retaining structures depends upon the load which is transferred from backfill soil as well as external loads and also the resisting capacity of the structure. The traditional safety factor approach of the design ... -
Seismic Response Of Geosynthetic Reinforced Soil Wall Models Using Shaking Table Tests
(2010-10-14)Use of soil retaining walls for roads, embankments and bridges is increasing with time and reinforced soil retaining walls are found to be very efficient even under critical conditions compared to unreinforced walls. They ... -
Concrete Fracture And Size Effect - Experimental And Numerical Studies
(2010-10-14)Most materials including concrete have pre-existing flaws or defects. The fracture energy of concrete is a basic material property needed to understand fracture initiation and propagation in concrete. Whether fracture ... -
Impact Assessment Of Climate Change On Hydrometeorology Of River Basin For IPCC SRES Scenarios
(2010-09-28)There is ample growth in scientific evidence about climate change. Since, hydrometeorological processes are sensitive to climate variability and changes, ascertaining the linkages and feedbacks between the climate and the ... -
Effects Of Reinforcement Parameters On The Behavior Of Geosynthetic Reinforced Foundation Beds
(2010-09-22)Use of geosynthetics for reinforcing soil beds supporting shallow foundations has gained tremendous popularity in recent times. In this thesis, to study and understand the behaviour of geosynthetics reinforced soil ... -
