Shaking Table Studies on Seismic Response of Unreinforced and Geosynthetic Reinforced Soil Slopes
Experiences from recent earthquake records all over the world suggest that reinforced soil slopes provide better resistance to the seismic forces and possess higher yield accelerations compared to unreinforced slopes. ... -
Novel Numerical Procedures for Limit Analysis: Implementation to Planar, Axisymmetric and Three-Dimensional Geomechanics Stability Problems
The Current research in the field of computational limit analysis dwells upon the development of numerical tools which are sufficiently efficient and robust to be used in engineering practices. This places demands on the ... -
Parameter Estimation to Determine the Groundwater Flow and Seawater Intrusion in a Coastal Aquifer of Karnataka, India
Seawater Intrusion (SWI) into the fresh groundwater aquifers is one of the major hydrological problems in coastal regions. This global issue is aggravated by increasing demands for fresh groundwater due to on-going ... -
Role of Gypsum in Stabilisation of Expansive Soil with Lime/Fly Ash-A Micro-Mechanistic Study
Stabilization of expansive soils with various calcium–based stabilizers (lime and cement) directly or in combinations with other solid waste materials such as fly ash and ground granulated blast furnace slag (GGBS) etc. ... -
Analyzing Inter-modal Competition Between High Speed Rail and Conventional Transport Modes in Indian Context
Indian Railway provides an important mode of public transport in India. This is the most commonly used and cost effective long-distance transport system of the country. Indian Railways has played an immense role in ... -
Retrieval of Land Surface Variables using Microwave Remote Sensing
Microwave remote sensing of the land surface processes has advantages over optical remote sensing such as least attenuation due to the atmosphere, and high temporal resolution among others. Soil moisture is an important ... -
Non-Local Continuum Models for Damage in Solids and Delamination of Composites
The focus of the thesis is on developing new damage models for brittle materials and using these to study delamination of composite structures. Chapter 1 gives an introductory literature review in order to motivate the ... -
Studies on Characteristics of Cement Stabilised Rammed Earth and Flexural Behaviour of Plain and Reinforced Rammed Earth
The rammed earth technique has been explored in the past, for the construction of load bearing walls in the buildings. Rammed earth construction involves compaction of partially saturated loose soil-sand mix in a rigid ... -
Seismic response of Geocell Retaining walls
Use of tensile reinforcement for improving the seismic stability of retaining walls has gained considerable attention in recent times and has become a very common practice. Compared to planar geosynthetic materials, geocells ... -
Non-classical mechanics and thermodynamics for continuum modelling of solids
This thesis dwells upon several aspects of continuum mechanics and thermodynamics to model elastic and inelastic response of solids. Broadly, the work presented may be categorized into two parts{ one focusing on the ... -
Strain-rate Dependence of Rock Joint Strength and Related Stability of Slopes and Tunnels
Understanding the strain rate-dependent strength behavior of rock joints is important since displacement rates along rock joints in field can exceed the suggested displacement rates (0.02 mm/min-0.5 mm/min) for laboratory ... -
Semi-active Control of Earthquake Induced Vibrations in Building Structures using MR Dampers: Algorithm Development and Benchmark Application
The thrust of this thesis is the development of two different kinds of feed-forward control strategy using the semi-active device MR damper to monitor MR damper supply current/voltage. The study develops a feed-forward ... -
Studies into Embodied and Operational Energy in Traditional and Conventional Residential Buildings in India
The role of the built environment and the construction industry in sustainable development gained global attention due to their significant share in global warming, GHG emissions, energy demand and depletion of non-renewable ... -
Behaviour of Granular Materials Under Shock and Blast Loading - A Shock Tube Investigation
Granular and porous materials based protective layers have proven to be very good shock absorbing medium. Although sand material is widely used (as sand bags) till date in civil and military applications as a blast mitigating ... -
Numerical Modelling of Reinforced Concrete Structural Elements and Assemblages Exposed to Thermo-mechanical Loading
Fire represents one of the extreme loads that a structure may experience during its design life. In reinforced concrete (RC) structures, the mechanical properties of both concrete and steel deteriorates with rise in ... -
Contaminant Transport through Soil and Effect of Bentonite and super-absorbent Polymer on Transport Parameters
(2018-08-20)The aim of this present research is to improve the containment properties of clayey soil by the use of bentonite and polymers as the additives. Clayey soils are generally used for the control of soil and water pollutions ... -
Studies on Flexural Behaviour of Fly Ash-Lime-Gypsum Brick Masonry
(2018-08-09)Varieties of masonry units such as burnt clay bricks, stones and concrete products are used for masonry construction. Even though these materials are durable, they are considered as unsustainable options because of the ... -
