Effect of Viscoelastic Dampers on Progressive Collapse Resistance of RC Building
Abstract: Natural as well as man-made hazards may cause the failure of the primary load bearing members of buildings. The spread of an initial local failure from element to element, eventually result into the collapse of an entire structure or a large part of it, which is known as Progressive Collapse. Progressive collapse initiates when one or more primary load bearing elements get fails causing failure of the entire structure. It …

Analytical Study on Optimum Placement and Sizing of X-Plate Metallic Dampers for Seismic Response Control of Multistoried RC Building Frame
Abstract: X-plate metallic damper (XPD) is one device that is capable of sustaining many cycles of stable yielding deformation resulting in a high level of energy dissipation or damping. For quantification of effectiveness of XPD, optimum placement and sizing of XPD are one of the practical interest. This paper investigates effect of placement and sizing of X-Plate damper on a G+3 square shaped building. The most optimal damper placement location pattern …

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 …

Non-Linear Dynamic Analysis of High-Rise Flat Slab Structure with Various Lateral Load Resisting System: Indian Scenario
Abstract: In this technological era, the construction of high-rise flat slab structure is increasing everywhere, due to its major advantages over a conventional beam slab structure. Due to the poor performance of high-rise flat slab structure in higher seismic zones, IS 1893 (Part 1): 2016 discourages the use of flat slab structure in higher seismic zones.

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 …
