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 …

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 …
