Comparative Study of Seismic Performance of Multistory Symmetrical RC Frame Structure with and Without Dampers
Abstract: This paper investigates the influence of friction dampers on the nonlinear seismic performance of multistory structure. The operational mechanism of these devices is that a large amount of energy inputting to the structure could be absorbed and the displacement of the structure is reduced. For this purpose, four types of frames are investigated with dampers at different locations. Three types of natural time histories are used for the nonlinear seismic …

Consideration of Collision Damage in FPSO Structural Design
Abstract: AbstractA collision event may be catastrophic for an offshore facility or a floating production, storage and offloading unit (FPSO). Depending on the size and speed of the impacting ship, anything from damage to hull rupture, oil pollution, flooding, loss of buoyancy, capsizing, and sinking may occur. Supply vessels and tankers frequently visit the FPSO to transport consumables and chemicals and, consequently, there is a risk of collision between two structures. …

Damping Power System Oscillations using Fuzzy based Power System Stabilizer with Seven and Nine Linguistic Variables
Abstract: Low-frequency oscillations are created in a power system due to insufficient damping. Low-frequency oscillations in a power system can be damped using conventional power system stabilizer (CPSS) or fuzzy-based power system stabilizer (FLPSS). The performance of FLPSS is significantly affected by the number of linguistic variables used in designing FLPSS. In this paper, FLPSS is designed to damp the low frequency oscillations in a power system. The novelty of the …

Role of Fatigue and Creep in Structural Damage: A Comprehensive Review
Abstract: Fatigue and creep are two critical degradation mechanisms that significantly influence the structural integrity and longevity of engineering materials. These phenomena arise due to different loading and environmental conditions but often coexist in various industrial applications, leading to severe material degradation over time. Fatigue primarily results from cyclic loading, where repeated stress variations induce microstructural damage and crack initiation, ultimately causing catastrophic failure. Conversely, creep occurs under sustained stress at …
