Harmonic Mitigation in Shunt Active Power Filter Regulation Approaches with Synchronous Reference Frame: An Extensive Analysis
Abstract: The Shunt Active Power Filter (SAPF) is discussed in this work as a means of removing line-side current harmonics. The Voltage Source Inverter (VSI) topology serves as the foundation for the Active Power Filter. It resolves the power system's harmonic current issue. Additionally, it balances the load on three phases and compensates for reactive power (if load is unbalanced). After measuring load current, it switches to the dq0 coordinate system. …

Effect of Outriggers Location on Performance of RC Building Subjected to Loss of a Column
Abstract: Progressive collapse denotes a failure of substantial part of the structure, causing greater damage to the structure than the initial impact, which has been initiated by failure of a relatively small part of the structure such as failure of any vertical load carrying elements (typically columns). Failure of large part of any structure will result into substantial loss of human lives and natural resources. Therefore, it is important to prevent …

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 …
