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 ... -
Vibration Testing of Structures under Random Support Excitations
(2018-07-30)Vibration testing of structures constitutes a crucial step in design and commissioning of engineering structures. The focus here is on simulating field conditions in a laboratory so that detailed investigations of the ... -
Site Characterization and Assessment of Various Earthquake Hazards for Micro and Micro-Level Seismic Zonations of Regions in the Peninsular India
(2018-07-28)Past earthquakes have demonstrated that Indian sub-continent is highly vulnerable to earthquake hazards. It has been estimated that about 59 percent of the land area of the Indian subcontinent has potential risk from ... -
Seepage Effects on Stream Power, Resistance, Incipient Motion and Regime of Sand Bed Channels including Its Design
(2018-07-28)Common behavioral trends and characteristics of alluvial channels including rivers are extensively discussed in the literature. However, little is known about the hydrodynamic effects of seepage on alluvial channels. Factors ... -
Uncertainty Quantification in Flow and Flow Induced Structural Response
(2018-07-23)Response of flexible structures — such as cable-supported bridges and aircraft wings — is associated with a number of uncertainties in structural and flow parameters. This thesis is aimed at efficient uncertainty quantification ... -
Static and Dynamic Behavior of Reinforced Masonry : Experimental and Analytical Investigations
(2018-07-18)The most common form of dwellings in rural and semi-urban areas of India and other developing countries around the globe are one/two storey unreinforced masonry (URM) buildings. It is well known that such masonry buildings ... -
Analysis and Modelling of Activity-Travel Behaviour of Non-Workers from an Indian City
(2018-07-16)Indian cities have been witnessing rapid transformation due to the synergistic effect of industrialisation, flourishing-economy, motorisation, population explosion, and migration. The alarming increase in travel demand as ... -
Structural Safety Analysis with Alternative Uncertainty Models
(2018-07-14)Probabilistic methods have been widely used in structural engineering to model uncertainties in loads and structural properties. The subjects of structural reliability analysis, random vibrations, and structural system ... -
Detection of Trends in Rainfall of Homogeneous Regions and Hydro-Climatic Variables of Tapi Basin with their Attribution
(2018-07-14)In the present work, methodology of statistical analysis of change evolved by Kundzewicz and Robson (204) is revised to obtain a robust methodology named as “Comprehensive Aproach” which addresses research gaps of earlier ... -
Testing of Ground Subsurface using Spectral and Multichannel Analysis of Surface Waves
(2018-06-29)Two surface wave testing methods, namely, (i) the spectral analysis of surface waves (SASW), and (ii) the multi-channel analysis of surface waves (MASW), form non-destructive and non-intrusive techniques for predicting the ... -
Response of Geosynthetic Reinforced Granular Bases Under Repeated Loading
(2018-06-21)Key factors that influence the design of paved and unpaved roads are the strength and stiffness of the pavement layers. Among other factors, the strength of pavements depends on the thickness and quality of the aggregates ... -
