(2018-02-10)Tee present research focuses on seismic hazard studies for the states of Tripura and Mizoram in the North-East India with taking into account the complex sesismotectonic characteristics of the region. This area is more ... -
Seismic Microzonation Of Lucknow Based On Region Specific GMPE's And Geotechnical Field Studies
(2016-09-09)Mankind is facing the problem due to earthquake hazard since prehistoric times. Many of the developed and developing countries are under constant threats from earthquakes hazards. Theories of plate tectonics and engineering ... -
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 ... -
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 ... -
Seismic Site Classification and Response Studies of Shallow Bedrock Sites
Among all-natural hazards, earthquakes are the most damaging in terms of loss of lives and damage to infrastructure. Amplification and liquefaction are the major effects of earthquake that cause massive damages to ... -
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 ... -
Semi-active Control Of Earthquake Induced Vibrations In Structures Using MR Dampers : Algorithm Development, Experimental Verification And Benchmark Applications
(2010-08-16)As Civil Engineering structures, e.g., tall buildings, long span bridges, deep water offshore platforms, nuclear power plants, etc., have become more costly, complex and serve more critical functions, the consequences of ... -
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. ... -
Shaking Table Tests to Study the Influence of Ground Motion, Soil and Site Parameters on the Initiation of Liquefaction in Sands
(2018-01-12)Liquefaction is a phenomenon in which soil loses a large percentage of its shear resistance due to increased pore water pressure and flows like a liquid. Undrained cyclic loading conditions during earthquakes cause ... -
Shape Characterization of Granular Particles using Image Based Techniques
(2018-05-22)Granular soils with different sizes and shapes are often used in many civil engineering structures. In different contexts, several researchers have emphasized that shape of particles play a pivotal role in influencing ... -
Shear Behaviour of GCL-Sand Interrfaces under Static and Dynamic Conditions
Geosynthetic clay liners (GCL) are unique geocomposites that combine the beneficial properties of bentonite clay and geosynthetics in providing effective hydraulic barriers in landfill systems. In landfills, GCLs form ... -
Shear Behaviour of Sand-geosynthetic Interfaces Based on Size And Morphology of Sand Particles and Surface Roughness of Geosynthetics
(2018-01-01)Geosynthetics are used in conjunction with soil/particulate materials to serve various functions like reinforcement, drainage, filtration and containment. The shear behavior of soil-geosynthetic interfaces hugely depends ... -
Simulation and Characterization of Streamflow Time Series
Streamflow can be partitioned into distinct time scales to better understand the underlying governing processes: fast flow, representing surface runoff controlled mainly by meteorological processes that operate over ... -
Simulation of complex plastic flows in metal sliding and cutting
Metal manufacturing encompasses a broad range of mechanical transformation processes that shape native metal into useful forms. These processes generally involve the interaction of a hard tool with a specimen / workpiece, ... -
Site Characterization and Assessment of Various Earthquake Hazards for Micro and Micro-Level Seismic Zonations of Regions in the Peninsular India
