Dynamic Analysis of Simply Supported Bridge under Vehicle Loads
Abstract: The analysis of dynamic behavior of bridge structures that are subjected to moving loads has been one of the enquiry interests in recent years. Specifically in railway bridges, reverberation ensues when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been practical in railway bridges especially subjected to high-speed lines. They are caused primarily because of two reasons: one is the repeated …

Strain Life Approach for the Fatigue Evolution Model of Concrete under Constant Amplitude Bending Fatigue Loading
Abstract: Strain life approach for the fatigue evolution model of concrete under constant amplitude bending fatigue loading plays a very important role in the material properties such as the fatigue strain, fatigue modulus and fatigue damage, presented in this paper by the nonlinear fatigue evolution model, and the hypothesis of recycle-ratio-related fatigue strain amplitude that causes stiffness degradation and inelastic deformation. The fatigue evolution model of concrete under constant amplitude bending …

Evaluation of Rutting Susceptibility of Bituminous Mixes Using Finite Element Modeling
Abstract: Pavement performance mainly depends on the quality of bituminous mixes. Poor bituminous mixes cause premature failures such as rutting or permanent deformation, cracking, bleeding etc. The design of bituminous mixes should contain certain criteria to prevent premature failures. The mixes designed based on these criteria are generally known as performance based mix design and are gaining popularity in the recent times. Among various types of pavement failures, permanent deformation or …

RUTTING EVALUATION OF BITUMINOUS MIXES USING WHEEL LOAD TESTERS
Abstract: Abstract: Permanent deformation also known as rutting, is the major mode of distress affecting the service life and performance of bituminous pavements. Rutting occurs due to excessive stresses on subgrade, inadequate strength of bituminous mix, inadequate thickness of pavement layers or poor construction methods. Among these causes, quality of bituminous mix is one of the main factors that contribute towards rutting failure.There are several test methods like Uniaxial tests, Triaxial …

ASSESSMENT OF FOUNDATION SIZE AND REINFORCEMENT USED FOR FOUNDATION BASE OF PIER FOR STEEL GIRDER RAILWAY BRIDGE.
Abstract: The analysis of foundation size and reinforcement is conducted with respect to the overall load exerted on the foundation base. This includes considering the load imposed by trains, the weight of the girder, and the pier. To ensure the structural integrity and stability of the foundation base, M25 grade concrete and Fe 500 grade steel are utilized. In order to counteract bending forces, 20 φ diameter steel bars are incorporated …

Treatment of Dyeing Waste Water by Using Garlic Extract as a Natural Coagulant
Abstract: Coagulation is the process of removal of very fine particles by forming bigger flocs in the water. But this process is not much efficient in waste water treatment as in the treatment of drinking water. This is because of adding chemical coagulant for the treatment of waste water. Use of chemicals in treatment of dyeing waste water causes formation of non-biodegradable sludge. To avoid this we made an attempt in …

Study on Analysis and Design in Reinforcement Structure Joints of Water Tank Structure for Safety Human life
Abstract: A water tank is used to store water to surge over the daily requirement. In the construction of concrete structure for the storage of water and other liquids the imperviousness of concrete is most essential. The permeability of any uniform and thoroughly compacted concrete of given mix proportions is mainly dependent on water cement ratio. The increase in water cement ratio results in increase in the permeability. The decrease in …
