Experimental and Analytical Studies on Damage Detection and Failure Analysis of Transmission Towers and Tower like Structures
(2017-12-07)The transmission line (TL) tower is an important component in electrical network system. These towers consist of members (angle sections) and connections (bolted connections) plus foundation, which act together to resist ... -
A multi-physics-based modelling approach to predict mechanical and thermo-mechanical behaviour of cementitious composite in a multi-scale framework
Concrete is a heterogeneous material whose constituents (e.g., cement paste, aggregate etc.) range from a characteristic length-scale dimension of a nanometre to a metre. Owing to the heterogeneity of concrete and the ... -
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 ... -
Repair and Retrofit Strategies for Structural Concrete against Thermo-Mechanical Loadings
(2018-01-29)Reinforced cement concrete (RCC) structures have become an important aspect in most of the buildings in our society around the world. Most of the multistoried reinforced concrete buildings house important institutions such ... -
Response of Plain and Reinforced Concrete Elements to Various Mechanical Loads
Reinforced concrete (RC) is being used for a wide range of structural applications. In order to design safe and economical RC structural elements it is necessary to analyse these elements accounting for the realistic ... -
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 ... -
Structural Health Monitoring Accounting for Thermal Variability and Damage using Approximate Bayesian Computation
In structural engineering, damage is characterized as a change in material property, boundary condition, or geometry. The changes in these properties/parameters lead to a change in the measured response. The difference ... -
Studies On Characterization Of Self Compacting Concrete : Microstructure, Fracture And Fatigue
(2013-09-11)Evolution of concrete is continuously taking place to meet the ever-growing demands of the construction industry. Self compacting concrete (SCC) has emerged as a result of this demand to overcome the scarcity of labour. ... -
Time Dependent Deformations and High Temperature Effects on Different Types of Concrete : Experimental and Numerical Studies
(2018-03-01)Estimating the delayed strains in concrete, namely creep and shrinkage is very important to asses the condition of the structure. Time dependent deformations in concrete, both creep and shrinkage, play a critical role in ... -
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 ... -
Uncertainty Based Damage Identification and Prediction of Long-Time Deformation in Concrete Structures
(2018-02-20)Uncertainties are present in the inverse analysis of damage identification with respect to the given measurements, mainly the modelling uncertainties and the measurement uncertainties. Modelling uncertainties occur due to ...
