Theoretical modelling of heat transfer in non-homogeneous porous media
Abstract: The paper is focused on the study and analysis of heat transfer in geothermal substrates made up of non-homogeneous porous media. The paper analyses the influence of porosity on the heat transfer as a result of the combination of conduction and convection mechanisms that take place in non-homogeneous porous materials. As a result of the combined effect heat transfer is not homogeneously distributed throughout the cross section of the geothermal …

Experimental Setup to Determine Stress Wave Propagation in a Compound Bar
Abstract: Deformation undergone by a body due to impact results in development of dynamic stresses. This deformation depends on the material properties and geometry. Advancements made in stress wave propagation are focused at the necessity to understand dynamic history of structures subjected to applied loads. Stress travels with different velocities in different bodies depending upon material characteristics, crystal structure etc. Forces applied on bodies at short intervals of time result in …

Review on Application of Utility Poles for Power Transmission
Abstract: Power transmission is generally carried out using transmission poles of various materials and cross sections. However, their utilization depends on climatic conditions and external loads acting on them. For an electric overhead system, the supports for the conductor and equipment must withstand the forces imposed on them, while the conductors themselves must be sufficiently strong enough to support their own weight and the forces imposed on them. The forces comprise …

Prediction of Punching Shear Capacity of Biaxial Voided Slab
Abstract: Biaxial voided slab systems are advantageous due to their reduced self-weight, up to 50 % in comparison with the conventional reinforced concrete solid slab. The reduction in the concrete cross sectional area reduces the shear capacity up to about 40 %. The prediction of punching shear capacity in voided slab is not direct unlike in solid slab. This is because the presence of voids alters the critical failure section and …

Computation of Different Stresses Acting on Cantilever Beam Using Hyperbolic Shear Deformation Theory
Abstract: The shear deformation effects are more significant in the thick beams. The classical beam theory (ETB) is based on Bernoulli-Euler hypothesis and the classical plate theory (CPT) is based on Kirchhoff’s hypothesis. The shear deformation effects are more pronounced in the thick beams when subjected to transverse loads than in the thin beams under same loading condition. These effects are neglected in elementary theory of beam (ETB). In order to …

Analysis of RC Frames Using Different Bracing Systems in Different Positions and Zones
Abstract: Structures are mainly built to enhance the performance of several activities like recreation, transportation, power generation, etc. They are built to sustain the loads coming on them during their service life by carrying adequate strength and also limit the deformation by possessing enough stiffness. Strength of a structure depends mainly upon the characteristics of material with which it is constructed. Stiffness is dependent upon the cross-sectional and geometrical properties of …

Study on Variation of Bond using Anti Corrosive Reagents on Reinforcing Steel Bar
Abstract: Variation of bond stress with different anti corrosive reagent was determined. When bar is embedded in concrete it is corroded in course of time and corrosion products form pit or holes on the surface of reinforcing bar and reduce cross sectional area of steel and also reduce bond capacity. To protect corrosion, different anti corrosive reagent are available in the market. But the effect of bond, of reinforcing bar with …

Influence of Corrosion on Flexural Strength of Concrete
Abstract: The large-scale infrastructure uses reinforcement concrete. It has been believed that protection to steel reinforcement by concrete is permanent. The influence of atmospheric corrosion of steel and its performance in concrete has been subject to controversy in the construction industry. Service life of reinforced concrete structure can be significantly reduced when the corrosion of reinforcing steel is initiated; the product of corrosion expands and occupies greater volume than original volume …

Torsional Strengthening of RC Beam using Ferrocement Jacketing
Abstract: Due to the type of loading on the structure, it is generally known that there are four structural actions: axial force, shear, bending, and torsion. The reinforced concrete beams are said to be subjected to torsion, when the point of application of lateral loads does not coincides with shear center of the beam. These loads may be due to loading pattern or connection of beam. Torsional failure is typically seen …
