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 ... -
Studies On Application Of Control Systems For Urban Water Networks
(2010-09-21)Management and supply of water in an urban water distribution system is a complex process, which include various complexities like pressure variations across the network depending on topography, demand variations depending ... -
Reliability Based Design Methods Of Pile Foundations Under Static And Seismic Loads
(2010-09-03)The properties of natural soil are inherently variable and influence design decisions in geotechnical engineering. Apart from the inherent variability of the soil, the variability may arise due to measurement of soil ... -
