1 Study of Provision of Shear Wall in RC Building with Vertical Irregularities
Dr. M N. Bajad, Harshita P. Patil

Abstract-A structure can be classified as irregular if it contains irregular distributions of mass, stiffness and strength or due to irregular geometrical configurations. Different codes prescribe different limits for these irregularities like as per IS 1893:2002, a storey in a building is said to contain mass irregularity if its mass exceeds 200% than that of the adjacent storey. If stiffness of a storey is less than 60% of the adjacent storey; in such a case the storey is called as “weak storey”, and if stiffness is less than 70 % of the storey above, then the storey is known as soft storey‟. In reality, many existing buildings contain irregularity due to functional and aesthetic requirements. However, past earthquake records show the poor seismic performance of these structures.

Govinda.K, Tarun.S, Dilip. M, Varun Reddy K.S

Abstract- The security breach issues are a major concern to household and many organizations like banks. We therefore need a firm hardware to avoid any such circumstances. Hence we intend to provide a security breach detection system that alerts the responsible individuals through communication mechanisms like providing a message alert at the time of breach. The detection system will sense the light incident on it and alerts the individual by providing a message to the mobile phone or any other communication device. This work intended to implement will also sense if there is any fire accident. By this we can safeguard the personal interests or valuables that need protection in our absence. Any intrusion through the detection system will alert us at any time or place where we might be. This security breach system can be used in banks, lockers and wherever protection is necessary for one's valuables. A database is maintained to know the whole record of the breaches if any. A time stamp is also provided to know the time at which the security breach is attempted. This paper proposes and implements a model for detection of light and temperature.

Hina Shrivastava, V.N. Bhartariya, Rahul Agrawal

Abstract- Use of advanced composites has resulted in outstanding achievements in several fields as well as aviation, marine and automobile engineering, medicine, medicine and sports, in terms of improved fatigue and corrosion resistances, high specific strength and specific modulus and reduction in energy necessities due to reduction in weight. The main aim of this work is to validate the standard results of steel shaft of vehicles with an acceptable composite shaft by the FEM. In present study Carbon-epoxy and steel shafts were compared with one another in terms of their deformation below same conditions as within the previous journal. The maximum total deformation happens in Steel below the given conditions. Carbon epoxy is best in terms of maximum deformation as these parameters created during this shaft are less when compared to steel. Weight is additionally reduced in carbon epoxy shaft as compare to the steel shaft by 74%. Therefore the carbon epoxy composite is providing great strength and less weight as compare to the standard automotive steel drive shaft.

6 Simulated Comparative Study of Tube Hydroforming Technique and Conventional Process in Manufacturing of Crash Box
Khurshed Alam, Richard Victor

Abstract- Tube hydroforming (THF) is a process of forming closedsection, hollow parts with different cross sections by applying an internal hydraulic pressure and additional axial compressive loads to force a tubular blank to conform to the shape of a given die cavity. This innovative manufacturing process offers several advantages over the conventional manufacturing via stamping and welding; a) part consolidation, b) weight reduction, c) improved structural stiffness, d) lower tooling cost, e) fewer secondary operations, and f) tight dimensional tolerances. To increase the implementation of this technology in the automotive industry, dramatic improvements for hydroformed part design and process development are imperative. The current development method of THF processes is plagued with long lead times, which is resulted from much iteration on prototyping. The formability of hydroformed tubular parts is affected by a large number of parameters such as material properties, tube geometry, complex dietube interface lubrication, and process loading paths. FE simulation is perceived by the industry to be a cost-effective process analysis tool compared to the conventional hard tooling prototyping.

7 Numerical Investigation of Airfoil and Flat Louvers on the Air Duct Intake
Ruby, Pavan Shrivastava

Abstract- Louver's configurations are presumptuous critical part in designing an air admission framework. On a gas turbine power station application, this fin can divert the wind current means into the compressor and for the framework's interior cooling. Be that as it might, the shape and set up of the louvers will impact the execution of a gas turbine. Discomposed wind current over the louvers might motivate weight drop of the admission air that prompts drop-off of the turbine work yield. During this examination we are reaching to analysis affect of width variation on Airfoils by exploitation CFD code. In present study we investigate the different cases by varying the width of louvers from 8mm to 16mm with 2mm intervals through CFD Simulations. From the simulation results obtained we found that greater the width induce greater pressure drop which is validate to previous researches. Cause for pressure drop is the formation of vortex due to flow separation across the louvers and it is easily visualized from velocity contours. Larger width provides increased distance for reattachment point, for creating larger vortex below the louvers and hence higher magnitude of flow separation is achieved. This vortex narrowed down the flow path between louvers causing increased velocity due to turbulence within that region, reducing the pressure as stated by Bernoulli’s Principle.

8 Fuzzy Logic Based MPPT for High Voltage Dc Gain for PV based DC Distribution System
V.Santhosh Kumar, N.Narendar Reddy

Abstract- This paper presents a configuration for a high step up dc voltage gain with fuzzy based mppt to maximize the output power to dc micro grid level for photo voltaic based dc distribution system. Because of nonlinear characteristics of PV cell, the maximum power can be extracted under particular voltage condition. Therefore, Maximum Power Point Tracking (MPPT) algorithms are used in photo voltaic system to maximize the output power. In this paper the performance of the proposed system is compared with Perturbation and Observation (P&O) and fuzzy logic based mppt technique. High step up dc voltage gain is obtained with coupled inductor and switched capacitors. Simulation results shows that fuzzy logic based MPPT with high step up dc voltage has the highest power transfer efficiency.

9 Development of Self Compacting Concrete Using Industrial Waste Materials
Vallepu Vishnu Vardhan

Abstract- Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete.Due to industrialization there is huge amount of red mud and foundry waste sand created. Aluminum is now consume during manufacture red mud which is used Red Mud and Foundry waste Sand are industrial waste and causing threat to environment so the reduce the cost of the construction also to make structure more durable, reduce problem of this material the project has been undertaken so that it can be used for construction fashion following points attempted. 1] To study the properties of foundry waste sand. 2) To blend to mix or to replace cement by different % by foundry waste sand. 3) To study properties of Red mud 4) To prepare the concrete by blending or by replacing the cement by Red mud 5) To study the comparativeness. Facing lot more problem of foundry waste. Very close to the Kolhapur there is project of steel industry, sand used for the formation of mould when the molds are opened the waste sand is dumped for the filling the low lying areas while doing this the agriculture areas is converted into barren area Because there is no. space for the waste other than the land filling similar case is in case of Aluminum industry where red mud is concluded to be waste. Which contains lot amount of bauxite and that is why red mud is also dump in the nearby areas here it is causing big threat for the society and it is disturbing the eco system of the environment. So it is the dire need to use this particular otherwise waste material for the constructive in such fashion in the case of concrete so that concrete which became cost effective as well as eco friendly. And hence this project is attempted.

10 Properties of Self-Compacting Concrete
Vallepu Vishnu Vardhan

Abstract- Compared to normally vibrated concrete (NVC), self-compacting concrete (SCC) possesses enhanced qualities and improves productivity and working conditions due to the elimination of compaction. SCC generally has higher powder content than NVC and thus it is necessary to replace some of the cement by additions to achieve an economical and durable concrete. The established benefits of using low volumes of fly ash in SCC, high volumes of fly ash in NVC and the search for uses of waste glass led to the research on the possibilities of use higher fly ash contents than hitherto and ground glass as an addition in SCC whilst maintaining satisfactory properties. Mix design methods, tests, target properties and constituent materials were selected. This was followed by investigating the influence of fly ash and ground glass on the mortar fraction of the SCC and then using these results to produce concrete mixes with the target fresh properties. Hardened concrete of these mixes were measured and the relationships between these investigated. The results show that for constant filling ability of the SCC, replacement of cement with fly ash or ground glass requires an increase in water/powder ratio and a reduction in super plasticizer dosage. Both additions degraded the passing ability, consistence retention and hardened properties but not to a prohibitive extent. Also the UCL method of mix design was extended to higher coarse aggregate contents and different additions. The project can lead to the use of higher volume fly ash and ground glass in SCC, thus widening the types of additions available for SCC, saving landfill and reduce CO2 emissions by the use of less cement.

11 Use of Recycled Aggregate Concrete
Vallepu Vishnu Vardhan

Abstract- Concrete having a 28-day compressive strength of 28 MPa was crushed at ages 1, 3 and 28 days to serve as a source of aggregate for new concretes, simulating the situation prevailing in precast concrete plants. The properties of the recycled aggregate and of the new concrete made from it, with nearly 100% of aggregate replacement, were tested. Significant differences were observed between the properties of the recycled aggregates of various particle size groups, while the crushing age had almost no effect. The properties of the concrete made with recycled aggregates were inferior to those of concrete made with virgin aggregates. Effects of crushing age were moderate: concrete made with aggregates crushed at age 3 days exhibited better properties than those made with aggregates of the other crushing ages, when a strong cement matrix was used. An opposite trend was seen when a weaker cement matrix was used. Some latent cementing capacity was seen in the recycled aggregates crushed at an early age.

Vallepu Vishnu Vardhan

Abstract- Micro-cracks are the main cause to structural failure. One way to circumvent costly manual maintenance and repair is to incorporate an autonomous self -healing mechanism in concrete. One such an alternative repair mechanism is currently being studied, i.e. a novel technique based on the application of biomineralization of bacteria in concrete. The applicability of specifically calcite mineral precipitating bacteria for concrete repair and plugging of pores and cracks in concrete has been recently investigated and studies on the possibility of using specific bacteria as a sustainable and concrete -embedded self-healing agent was studied and results from ongoing studies are discussed. Synthetic polymers such as epoxy treatment etc. are currently being used for repair of concrete are harmful to the environment, hence the use of a biological repair technique in concrete is focused. Recently, it is found that microbial mineral precipitation resulting from metabolic activities of favorable microorganisms in concrete improved the overall behaviour of concrete. Hence in this paper define the bacterial concrete, its classification and types of bacteria, chemical process to fix the crack by bacteria, advantages and dis-advantages and possibilities of application of MICP (Microorganism used for Calcium Carbonate Precipitation in Concrete) in construction area by literature review are discussed.

Vallepu Vishnu Vardhan

Abstract- The use of recycled aggregates in concrete opens a whole new range of possibilities in the reuse of materials in the building industry. This could be an important breakthrough for our society in our endeavors towards sustainable development. The trend of the utilization of recycled aggregates is the solution to the problem of an excess of waste material, not forgetting the parallel trend of improvement of final product quality. The utilization of waste construction materials has to be related to the application of quality guarantee systems in order to achieve suitable product properties. Therefore, the complete understanding of the characteristics of new material becomes so important in order to point out its real possibilities. My thesis aimed to focus on the possibility of structural use of recycled aggregate concrete by studying the mechanical properties and durability aspects of conventional aggregate concrete, recycled aggregate concrete and fibre reinforced recycled aggregate concrete.
