Progressive Collapse Prevention Analysis of Multi-Storeyed Buildings by Using Pushover Analysis
Abstract: AbstractThis paper investigates an actual structure’s potential to break due to progressive collapse. This report looks into the progressive collapse resistance of high-rise RC structures. Progressive collapse of building constructions, primarily concentrates on concrete structures. Progressive collapse of a structure occurs when major structural load carrying members are removed suddenly. A progressive collapse is initiated as a consequence of local structural damages. It produces a chain reaction mechanism, into a …

Finite Element Modelling of Contact Stresses in Helical Gear Systems
Abstract: Helical gears are widely used in modern power‐transmission systems because of their high load‐carrying capacity, smooth meshing action, and increased overlapping of gear teeth. However, the design of helical gear pairs is constrained by contact stresses generated at the mating tooth surfaces, which can lead to surface fatigue (pitting), micro-cracking, and ultimately gear failure. Traditional analytical methods, such as those of the American Gear Manufacturers Association (AGMA) or International Organization …

Effect of Initial Temperature and Diameter of Ethanol Droplet on Evaporation Dynamics in Convective Air Medium
Abstract: Ethanol is a suitable biofuel as it has fewer toxic emissions and higher-octane numbers. For spray combustion applications, the gas phase motion must be considered while numerically investigating the fundamental aspects of droplet evaporation and combustion processes. Hence, we have numerically simulated the evaporation dynamics of an isolated spherically shaped ethanol droplet under a forced convective air environment in the absence of gravity. The momentum transfer between two phases is …
