Title : Comparisons Between Construction of Pre Engineered Building and Conventional Building
Country : India
Authors : M.S.K.Chaitanya || M.Venkat Rao || G.Aditya

Abstract: The present construction methodology for buildings calls for the best aesthetic look, high quality & fast construction, cost effective & innovative touch. India being a developed country massive house building construction is taking place in various parts of the country. Since 30% of Indian population lives in towns and cities hence construction is more in the urban places. Hence one has to think for alternative construction system like pre-engineered steel buildings. India has an installed steel capacity of 35 to 40 million tones & apparent steel consumption is around 27 to 30 million tones. There is a surplus capacity of flat steel products available in India particularly of hot and cold rolled sheets...........

Title : Effect of 3-D Modeling on Design of Pre-Engineered Steel Buildings
Country : India.
Authors : Ramesh Vasudeo Meghrajani || Dr. R. K. Ingle

Abstract: Professional engineers in Pre-engineered buildings (PEB) generally adopt two dimensional (2-D) modeling of frame i.e. plane frame modeling in transverse direction and profess for optimal design using elastic method. In practice, 2-D modeling of main frame is done for transverse frame while in longitudinal direction truss analogy is adopted mainly for analysis of bracing. In 2-D analysis majority of cases only major axis moment is considered and the minor axis moment (having sometimes significant effect on design) is generally ignored. This minor axis moment can be of less magnitude if the bracings are of X type designed as compression as well as tensile members..........

Title : Cultural Expressions In Architecture – A Case Of Manapad In The Coastal Stretch Of Tuticorin
Country : India
Authors : Dr.P.Jayasudha || Ar.Tony Marcel Nisha

Abstract: Through architecture it's possible to gauge many things about a culture, such as lifestyle, artistic sensibilities and social culture". Residential architecture evolved basically for the need for shelter, to protect people from harsh weather conditions and other disasters. They built these shelters based on the climate, available materials, known techniques, their culture, lifestyle and socio – economic factors. Climate plays a major role in deciding the house forms in a place like the roof forms in a shelter, to an extent the size and volume of spaces, sequence of spaces and material usage too. However it is culture which details out the treatment or articulation of a built form..........

Title : Experimental analysis of comparative temperature and exergy of crystalline (c-Si) and amorphous (a-Si) solar PV module using water cooling method
Country : India
Authors : Prabhat Kumar || Vishal Gupta || K.Sudhakar || Ajay Kumar Singh

Abstract: The objective of the research is to minimize the amount of water and electrical energy needed for cooling of the solar panels, especially in hot arid environment. A cooling system has been developed based on water spraying of PV panels. A mathematical model has been used to determine when to start cooling of the PV panels as the temperature of the panels reaches the maximum allowable temperature (MAT). Both models, the heating rate model and the cooling rate model, are validated experimentally. Based on the heating and cooling rate models, it is found that the PV panels yield the highest output energy if cooling of the panels starts when the temperature of the PV panels reaches a maximum allowable temperature (MAT)...........

Title : Partial replacement of river sand with volcanic pyroclastics as fine aggregates in concrete production
Country : Kenya
Authors : Okwadha G.D.O., Ph.D || Ngengi K.J.

Abstract: The most commonly used fine aggregate in concrete production is river sand. Its extensive mining has led to massive environmental degradation. Volcanic activity in most parts of the world has deposited enormous amounts of pyroclastics especially volcanic tuff and lapilli which can be used to reduce overdependence on river sand. The effects of sand-pyroclastics mixture on workability of fresh concrete, absorption and compressive strength of cured concrete were investigated. Factorial experiments were done with 0%, 25%, 50%, 75%, and 100% sand replacement by weight of sand...............

Title : Wind Tunnel Testing of a Small Wind Turbine Darrieus-H, With Asymmetric Airfoil, For Auto Start
Country : Argentina
Authors : Jorge Lassig || Juan Valle Sosa || Ubaldo Jara

Abstract: The Darrieus model was invented by a French engineer named George Jeans Maria Darrieus. He presented his patent in 1931 in the US [1] which included curved and constant section blades, now called Darrieus-H or Giromill. Its boom was won between the 1970s and 1980s, and then was dismissed for various reasons, compared with horizontal axis turbines [2].In particular, vertical axis wind turbines Darrieus type today are being considered as one of the most attractive solutions to be installed on roofs of buildings (auto sustainable buildings), due to its low visual impact, reduced noise emissions and better response to a turbulent flow [3]............

Title : Layering consideration of FG plates and the calculation of their critical buckling load
Country : Iran
Authors : Amin Hoseinpour Khoshghalb || Alireza Ahmadi || Reza Dehghani

Abstract: The aim of this article is the evaluation of P-FGM buckling force with simply supported boundry condition by the ABAQUS software. The FGMs are the improved and novel materials that are micro-structurally inhomogeneous and their mechanical properties changes continuously along thickness. Generally these materials made of metal and ceramic composition. The Poison ratio of this plates is constant and supposed that the material properties are changed as a power law function along the plate thickness. The loads are in-plane. The results are compared with analytic results for validation. Then the effect of thickness changing and buckling modes are plotted. Also it can be seen that the behavior of FG plates are similar to Isotropic plates. The results are obtained for the plates of Alminum-Alumina.

Authors : Pratik Karkare || Prof. Kamlesh Gangrade

Abstract: As we know that safety of the vehicle is the first and the fore most thing to be considered in 2-wheelers the safety of the vehicle from accident was understated on two major factors: Directional stability and the Aerodynamic force both are correlated to each other. The former is stability of a moving body or vehicle about an axis which is perpendicular to its direction of motion. Stability of a vehicle concerns itself with the tendency of a vehicle to return to its original direction in relation to the oncoming medium (water, air, road surface, etc.)...............

Abstract: Nowadays, sustainable building is a responsibility within construction and the use of bearing walls made of compressed earth blocks, rammed earth, poured earth, among other earth building techniques, has become more frequent. Nevertheless, generally these structures must be found over foundations that correspond to the conventionally used reinforced concrete. Even though from a sustainable point of view, the use of stone is accepted, within the cases of zones where this material does not exist, it is necessary to develop new ecologic technologies compatible with the elements it sustains...............

Title : Finite Element Analysis of Funicular Shells with Rectangular plan ratio 1:0.7 under Uniformly Distributed Load using SAP2000
Country : Iran
Authors : Siddesh T M || Harish B A || Dr. K Manjunatha

Abstract: A thin shell is a "Three-dimensional spatial structure made up of one or more curved surfaces whose thickness is small compared to their other dimensions". Shells belong to the class of stressed skin structures which, because of their geometry and small flexural rigidity of the skin, tend to carry loads primarily by direct stresses acting in their plane. The shells are subjected to pure membrane state of stress, under appropriate loading and boundary condition the resulting bending and twisting moments are either zero or small which may be neglected...............

Country : Indonesia
Authors : Anita Rauzana

Abstract: The success of a construction project depends on the cooperation between the parties involved, namely the building owners, contractors and project planners. Many factors could hinder the implementation of construction projects. The success of carrying out construction projects on time without any obstructions in the implementation is one of the most important goals. Project construction experience obstacles and constraints in implementation is a condition that is very undesirable, because it would be very detrimental to all parties.

Country : Malaysia
Authors : Murtada Sadah Mohsin || Abdul Kadir Marsono

Abstract: Precast technology grows rapidly around the world. One of the frequent topic discussions now is the concrete precast block that can flexibility assemble to form a house quickly. In this topic the test consists of T-shape and L-shape and square shape are used to form columns. The blocks was designed in a way which that it can lock to each other and can form a columns. In this research, a test was carried out to determine the behavior of the columns in nonlinear state at various post-tension forces by applying 4 cyclic loads. The post-tensioning effect on the column behavior was better and lateral displacement reduced in IBS block work system

Title : Investigation of Process Parameters Optimization in Die - Sinking Edm to Improve Process Performance Using Taguchi Technique
Country : India
Authors : Dr.T.Vijaya Babu || Dr .J.S Soni

Abstract: Electrical discharge machining (EDM) is a well-established machining option for manufacturing geometrically complex or hard material parts that are extremely difficult-to-machine by conventional machining processes. The non-contact machining technique has been continuously evolving from a mere tool and dies making process to a micro-scale application machining alternative attracting a significant amount of research interests. This involves optimization of the process parameters by relating these with the performance measures maximizing the MRR, while minimizing the TWR and yielding the desired SR..............

Title : Aero Thermodynamic Structural Topology Optimization Of Hypersonic Re-entry Capsule By Using CFD
Country : India
Authors : P.Harish || A.S.Shabaz

Abstract: A re-entry capsule is the portion of a spacecraft which returns to earth following a space flight. In present paper, a fluent analysis is performed on two distinctive models of capsule and temperature contours are outlined. Firstly, the aft end formed in a sharp (slender body) shape forms a shock wave that touches the capsule and high temperatures are formed on the body, Whereas, the aft end is formed in a rounded (blunt body) shape, as this forms a shock wave that doesn't touch the capsule, and the heat is diverged away rather than melting the vehicle body and low temperatures are seen on the body. The capsule model was created in Solid Works, meshing and general post processing was carried out in Ansys fluent 14.0
