Structural response of partially steel-fibre-reinforced concretes
Improvements in fatigue strength, improvements in strength under pure torsion and under combined bending and torsion with the addition of fibres to concrete, and the possibility of steel fibres taking over conventional ... -
Prediction of compaction characteristics of soils
PREDICTION OF COMPACTION CHARACTERISTICS OF SOILS Fine-grained soils with appreciable clay fractions are being placed in earth dams and highway embankments by geotechnical engineers more often than in the past, sometimes ... -
Flow characteristics of hydrofoil weirs, hydrofoil topped weirs and streamlined triangular profile weir
This thesis deals with free and submerged flow characteristics of different shapes of streamlined weirs, which include hydrofoil weirs, hydrofoil topped rectangular weirs, and streamlined triangular profile weirs. In all, ... -
Optimisation technique for evaluation of aquifer parameters
This thesis presents results of an extensive computational study on the evaluation of parameters in different types of aquifers based on the optimisation of an objective function using the least squares approach. The ... -
Studies on mechanics of fibro Reinforced cement Based Composites
Fibre reinforced cement-based composites are now well recognized to be a promising new construction material. The use of short discrete fibres is relatively new in spite of the concept of fibre reinforcement being recognized ... -
Some problems in the inelastic response of structures subjects to earth quakes
In this chapter, bilinear-hysteretic response of a one-storeyed building structure to several real earthquakes is discussed. The structure, consisting of a rectangular slab supported on a series of portal frames, is assumed ... -
Confined concrete and reinforced concrete members undermonotonic, repeated and reversed loading
Ductility is of considerable importance in the case of reinforced concrete structures subjected to both static and dynamic loading. The required large ductility of a structure can be achieved by designing the members of ... -
Numerical modelling and analysis of solute transport in a single fracture
Studies of non-reactive tracer movement in porous formations exhibiting heterogeneity due to variation in hydraulic conductivity have been the subject of considerable research over the past several years. These studies ... -
Fracture Mechanics Based Residual Strength Assessment of Concrete Members under Fatigue Loading
Although concrete is one of the most widely used building materials in the world, there are gaps in our understanding of its behavior under fatigue loading conditions. Structures are subjected to numerous load applications ... -
Response stability and catastrophoes of stochastically parametered structural systems
Vibrational and stability behaviour of structural systems having stochastically distributed material properties and subjected to stochastic loadings in space are the concerns of this thesis. The Young’s modulus and mass ... -
Viscoplasticity and geometric nonlinear finite element analysis of adhesively bonded LAP joints
Adhesivebonded joints are usually preferred in composite structures due to their intrinsic advantages compared to fastener joints. Adhesivebonded joints have major advantages such as minimal sources of stress concentrations, ... -
Lower bound limit analysis and design of reinforced concrete rectangular slabs
It is becoming increasingly necessary to use reinforced concrete slabs with different end conditions - fixed (partially or fully), continuous, simply supported, or even free. The understanding of their strength, structural ... -
Analysis and parameter estimation models for on aquifer-water table aquitard system
The present study is concerned with developing analysis and parameterestimation models for groundwater flow to a well in a twolayer leaky system comprising an aquifer-watertable aquitard. Previous studies analyzing such a ... -
Optimal reservoir operation for irrigation
Irrigation is an important purpose for which most reservoirs are operated in developing countries. There is an increasing awareness among irrigation planners and engineers to plan and operate reservoir systems at maximum ... -
Critical cross power spectral density models for earthquake loads on multi-supported structures
The response of a doubly supported MDOF system under differential earthquake ground motions has been studied in this chapter using the principles of linear randomvibration theory. The earthquake ground motions are modeled ... -
Hydraulic transients in pumping systems with air chambers
This thesis presents the results of an extensive computational study of the transients in pumping mains following power failure and singlepump tripping. The studies are of practical relevance to pumping mains of watersupply ... -
Mathematical theory and experimental verification of approximate linear weirs and self-basing linear weirs
The analysis of the thesis emphasizes the possibility of using geometrically simple weirs formed by straight lines and/or circular quadrants as effective, sufficiently accurate linear weirs in irrigation and other allied ... -
Random Vibration of limit cycle systems and stochastic strings.
The behaviour of the Van der Pol oscillator under periodic excitation is well known. The effect of adding noise to the excitation has been studied in this chapter. Three different solutions are obtained based on the Gaussian ... -
The analysis of unreinforced brick masonry Vaults
There has been a revival of interest in unreinforced brick masonry vaults in recent years. The present thesis deals with studies on smallspan brick masonry vaults with a view to developing an understanding of their structural ... -
Finite Difference Modelling of Seepage and ground water flows
The thesis presents several studies in finitedifference modelling of seepage and groundwater flow. After presenting a literature review on the available methods for finitedifference models in groundwater flow, the scope ...
