Productivity of Hydraulically Fractured Calcite Rich Shale Reservoirs Enhanced by Acid
Abstract: The current low oil prices have highlighted the need for enhancement to current production from shale formations. Prolonging the production life and increasing productivity of the fracture network in the shale plays can be a way to improve the economics. Many shale wells, drilled and completed based on current completion strategies, show sharp decline after initial flash production. One of the reasons behind this can be attributed to closure of …

Torsional Effect on Multi-Storeyed Building on Regular and Irregular shape of Building with and without Infill by Using P-Delta Analysis
Abstract: Torsional effect on structure is the modified seismic response of building which caused several damages or collapse of structure. P-Delta effect are the second order effects which increase lateral displacement in which the lateral displacement can be caused by wind or seismically induced inertial forces in the high rise structure. The increase in number of storey in the structure directly proportion to the delta effect in the structure. The present …

Seismic Analysis of Symmetrical and Unsymmetrical Multistory Building with Shear Wall and Hybrid Shear Wall
Abstract: Shear walls are structural systems which provide stability to structures from lateral loads like wind, seismic load. Shear walls are added to the building interior to provide more strength and stiffness to the building when the exterior walls cannot provide enough strength and stiffness. It is necessary to provide these shear walls when the tolerable span width ratio for the floor or roof diaphragm is exceeded. Shear walls are mainly …

Effect of Strong Column Weak Beam Concept on Seismic Capacity of Buildings of Varying Heights: A Review
Abstract: The strong-column-weak-beam (SCWB) layout philosophy in which plastic deformation is authorized to arise most effective with inside the beams whilst the columns continue to be basically elastic is broadly followed in seismic layout codes for metallic second frames. Under this yield mechanism, the seismic strength is dissipated ordinarily with the aid of using the plastic hinges with inside the beams and on the column bases. The relative plastic flexural capacities …

Study of Diagonal Ties and Metal Plate as a Confining Reinforcement for RCC Short Columns
Abstract: Column is a most important structural member in the structural system. Even after the strong column weak beam theory used in the design of the structural member it has been observed that the many times structure collapsed due to the failure of the column. There are many reasons of the column failure but out of that major reason of the failure is ineffective confinement of the column specimen and uneven …

“FORCE-DISPLACEMENT TRADE OFF” OF RCC BUILDING LOCATED AT VARIOUS SEISMIC ZONES AND SITE CONDITION ADOPTING TIME-HISTORY ANALYSIS
Abstract: Earthquake-resistant or aseismic design are considered to protect buildings to some or greater extent from earthquakes. The force-displacement trade off of structures located in various seismic zones are different in nature depending on intensity of earthquake. No structure can be fully immune to damage from earthquake, the vulnerability can be reduced for safety and durability. The force-displacement behavior of a particular structure can be modified to withstand seismic occurrence preventing …

Application and Limitation of Metal Thermochemical Processing
Abstract: The technically intriguing and monetarily feasible technique for enhancing the surface layer of materials is surface engineering. The aim is to establish a vast scope of useable attributes that are separate from the core substrate, together with physical, chemical, electrical, electronic, magnetic, or mechanical, even though the material surface monitors the operational life throughout many implementations. The thermochemical intervention, a type of surface engineering, uses heat diffusion to incorporate non-metal …

Seismic Analysis of Elevated Intze Type Water Tank
Abstract: As known from previous occurrences, Elevated water tanks were heavily damaged or collapsed during earthquakes. This might be due to lack of knowledge about seismic behaviour of water tank or improper geometrical selection of staging patterns. The staging plays critical role in design of water tanks as in water tanks large mass is supported by slender staging. The main objective of this study is to understand the seismic behaviour of …

X Plate Damper for Seismic Response Control of the Building
Abstract: The building system causes excessive vibrations during the seismic event which can lead to the complete collapse of a building, bridges etc. resulting in damage to the structure. Hence, the safety of the structures is essential to keep the building functional during and after the effects of the earthquake. To overcome these damages, additional energy dissipation systems are considered for the seismic protection of the building. The aim of the …

Damage Assessment in Reinforced Concrete Structures
Abstract: Reinforced concrete structures are subjected to a pattern of loading in addition to deterioration with age during their service life, which lead to damage of the structure. Damage assessment is an integral part of structural health monitoring (SHM) which aims to detect, locate and quantify the damage as well as predict the remaining service ability of the structure. Damage assessment technique can be classified into either global or local methods. …

A Comparative Evaluation of a 13-story G+ Building with a Soft Storey, Using Pushover Analysis, with a Focus on the Impact of Different Placement of Shear Walls
Abstract: Asymmetrical structures with varying degrees of irregularity have proven to be a significant factor in causing collapses, damage to property, and injury during earthquakes. Despite extensive research on asymmetric buildings, there are currently no established guidelines for multi-story structures of this type. A soft storey, also known as a weak storey, is a level in a structure with insufficient rigidity or ductility to sustain earthquake-induced damage Pushover analysis has been …

Effect of Panchtikt Ksheer Basti in Management of Avascular Necrosis of Head of Femur (Case Study)
Abstract: AbstractAvascular necrosis (AVN) is temporary or permanent loss of blood supply to bone. Without blood, the bone tissue dies and ultimately the bone may collapse. Without treatment, the process is almost always progressive, leading to joint destruction within five years. AVN accounts for more than 10% of total hip replacement surgeries performed. A diagnosed case of male patient with complaint of severe pain in right hip joint and upper aspect …

Obstruction Organizing Network Based Protocol Using Congestion Free Router
Abstract: AbstractThe web’s wonderful quantifiability and strength lead to half from the end-to-end nature of internet congestion management. End-to-end congestion management algorithms alone, however, are unable to stop the congestion collapse and unfairness created by applications that are unresponsive to network congestion. To address these maladies, I propose and investigate a unique congestion-avoidance mechanism referred to as Congestion Free Router (CFR). CFR entails the exchange of feedback between routers at the …
