Country | : | India |
Authors | : | Ashok Kankuntla || Prakarsh Sangave || Reshma Chavan |
Abstract: In high rise building shear wall is used to resisting the lateral loads that may be induced by the effect ofwind and earthquakes. In high rise building increases sizes of structural element. As a result consumption of conventional construction materials like concrete and steel goes on increasing day by day in the structures. On the other hand time delay is the key factor that will affect overall growth of such projects. Hence in order to overcome these constraints economical construction methodology and optimization techniques should be used. Finite Element Modeling now a days is an essential approach in analyzing and simulating civil engineering problem numerically. In this paper at attempt is made to apply the finite element modelling in analyzing and exploring the behavior of shear wall with opening under seismic load action on member forces. Hence the aim of present study is to compare seismic performance of 15-Storey with openings in shear wall situated in earthquake zone V.

Authors | : | Abid Ahmad Sofi || Sheikh Mohamad Iqbal || Suhail Ahmad Mir || Mohmmad Vekas Wani || Er. Aeijaz Masoodi |
Abstract: In this research, the issues of grounding problems in transmission towers during lightening and economic concerns of communication and transmission are addressed by using of waste coke powder rich with carbon in concrete foundation of towers.In case of transmission towers the compressive strength of underground concrete foundation is of less concern but should be more conductive for providing a continuous flow path for high voltage electric current up to deeper depths safely. The coke was oven dried ground finer and sieved through 150 micron IS sieve.The finely powdered coke were added as 2%, 4%, 6%, 8%,10% and 12 % by weight of cement for M-30 mix. The concrete were tested for workability in the fresh state and concrete specimens for compressive strength, durability density and conductivity at 28 days of age and the results obtained were compared with those of normal concrete. The results concluded the permissible dosage of using coke powder as partial replacement of cement up to 10% by weight for coke particle size finer than 150 microns. This form of concrete can be called as "Cokecrete". Keywords: Coke powder, Sustainability, Grounding, Conductivity, Concrete foundation.

Title | : | Concrete beams Flexural under sustained loading |
Country | : | Tunisia |
Authors | : | Abdelmonem Masmoudi || Mongi Benouezdou || Jamel Bouaziz |
Abstract: Steel reinforced concrete structures are susceptible to corrosion in severe environments. Corrosion limits the service life of structures, and results in expensive maintenance costs. GFRP composite bars are excellent alternative to steel bars for reinforcing concrete structures in severe environments. However, there is limited experience with the design and construction of GFRP reinforced concrete structures. This report investigates some parameters used in design of GFRP reinforced concrete members following the Eurocode 2 recommendations. A ratio of Agfrp bar reinforcement equal to 2% is recommended to a stabilization of the constraint in the bar. The compressed part of the concrete must be limited and does not exceed 40% useful height of the beam.
Keywords: GFRP Bar reinforcement, failure, Flexural design, Sustained loading

Authors | : | P. P. Kale || M. B. Patil || D. N. Korade || K. R. Jagtap |
Abstract:Vacuum cleaners are most commonly used housekeeping and industrial equipment and it is also most powerful source of noise. A reduction of this noise has many advantages, especially in commercial applications. In this work a wet and dry type vacuum cleaner (WD1450) is investigated for exhaust noise. Exhaust air of vacuum cleaner coming with high velocity is one of the main sources of noise in vacuum cleaner. To reduce exhaust noise of vacuum cleaner absorptive muffler is used. Aerodynamic performance of exhaust muffler is investigated by CFD (Computational Fluid Dynamic) method in terms of back pressure. With the help of CFD, simulation of pressure distribution in the muffler is done. Back pressure is an important parameter for muffler performance and it is predicated by CFD technique. Experimentation is done to determine the effect of muffler on the performance of a vacuum cleaner and amount of noise reduced. Efficiency and exhaust noise of the vacuum cleaner is reduced by 11.23% and 1.1 dB respectively by using absorptive muffler. Keywords: Absorptive muffler, Backpressure, CFD analysis, Vacuum cleaner noise, Wet and dry vacuum cleaner.

Title | : | Design Development and Testing of Hydraulic Engine Mount Isolation in Agricultural Applications |
Country | : | India |
Authors | : | T. S. Dol || D. N. Korade || P. D. Darade || K. R. Jagtap |
Abstract:The ideal engine mount should isolate engine vibration caused by unbalanced force in the engine speed range and prevent the engine bounce from shock excitation. For Agricultural applications like power weeder, grass trimmer Hand Arm Vibrations (HAV) are experienced by the operator continuously. It is also observed that some agricultural equipment has no any vibration isolation device to damp these excessive vibrations. Conventional mounts such as rubber mounts fail to provide better performance during damping vibrations due to some limitations. These troubles are overcome by hydraulic engine mount. In this work, a new configuration of hydraulic engine mount is designed for vibration isolation. Solenoid actuator makes this passive mount to the active engine mount..

Title | : | Determination bearing capacity of driven piles in sandy soils usingArtificial Neural Networks (ANNs) |
Country | : | Iran |
Authors | : | Ahmadreza Mazaheri || Mazaher Berneti |
Abstract:Due to some effective factors such as inhomogeneity of soil environment surrounded one pile, implementation of pile, pile material and its shape, correct estimation of pile load carrying capacity is difficult. However, pile load test with a high accuracy can be used as a reliable method in different steps of design and analysis, it is costly and its implementation takes long time in civil projects. This imposed some limitation on using this test. In contrast, modeling by artificial neural networks is a method which doesn't require simplification and use of high reliability coefficients and is based on pervious data and information.

Title | : | Flexural Fatigue Behavior of R.C. Beams Strengthened with Externally Prestressed CFRP |
Country | : | Sudan |
Authors | : | Mansour Ahmed Mohamed |
Abstract:This paper investigated, experimentally, the flexural performance of reinforced concrete beams strengthened with externally post-tensioned Carbon Fiber Reinforced Polymer (CFRP) tendons, under fatigue loading. Fatigue experiments on five beams (160x280x3500 mm) were undertaken. Mid-span –deflection, steel bar and CFRP tendons strain and cracks width were measured at different numbers of load cycles and varying fatigue loading levels during the test . Test parameters included the tendon profile and the load levels applied to the beam during the fatigue life (27%, 35%, 43% and 48% of their ultimate load). The CFRP tendons were post-tensioned at 35%, 40%, 45% and 55% respectively of its ultimate capacity. The empirical equation for crack width was established using curve fitting at various fatigue loading levels and numbers of load cycles. The fatigue performance of reinforced concrete beams strengthened with externally prestressed CFRP tendons was evaluated.

Title | : | Electrochemical behavior of reinforcing steel for nuclear reactor containment buildings |
Country | : | United Arab Emirates |
Authors | : | Maryam Qasem || Yongsun Yi || Sara Al Hanaei || Pyungyeon Cho |
Abstract: Electrochemicalbehavior ofcarbon steel for nuclear reactor containment buildings was investigated using potentiodynamic, potentiostatic, and galvanostatic polarization techniques in Ca(OH)2 solutions with NaCl. From potentiodynamic and potentiostatic polarization tests, it was found that the occurrence of pitting on the carbon steel in the solutionswas strongly dependent on the applied potential and chloride concentration. Metastable pitting that has usually been observed on stainless steels in chloride containing solutions was not observed on the carbon steel used in this study.Using galvanostatic polarization technique, the chloride threshold conditions of the carbon steel were evaluated. First, samples were pre-passivated in Ca(OH)2 solutions without NaCl for 2 days by immersion.

Authors | : | B. Adinarayana || Mnane Sr Rohit |
Abstract: Vehicle crashes are a major concern in rapidly growing urban agglomerations. They also have attracted the attention of researchers, academicians, and policy makers. A large body of research literature exists that throws light on the magnitude of this problem and also indicates the interventions required. In a vast majority of Indian cities, buses are the main mode of public transport. An externality of the bus-based public transport system, like any other mode of transport, is the injuries and fatali-ties arising out of the crashes involving them. Buses are involved in 12-20 percent of fatal crashes in Indian cities.
