A tuned mass rocking wall (TMRW)-frame structure system is proposed to improve the energy dissipation ability of traditional wall-frame system. Based on principle damper (TMD), a TMRW designed with proper and stiffness according dynamic characteristic host structure. Firstly, considering presence inherent structural damping, amplification factor main was derived from equations mechanism. practi...

Submerged floating tunnels with suspension supports (SFTSS) resemble to bridges on lands, which are installed a number of hangers the main tower and cables support girder. On other hand, as SFTSS underwater has resist buoyancy forces in an offshore environment, cable was at bottom tunnel body connected hanger. The concept first proposed by Won et al (2019, 2022). It found that generated itself ...

Recent developments in engineered timber products, and their availability, durability, renewability, have led to taller more flexible buildings. However, these buildings may experience excessive vibrations, resulting safety serviceability issues due wind or earthquake loads. This paper presents a dynamic analysis of 42-story-tall hybrid-timber building, along with comparative study the performa...

Abstract Dynamical and structural systems are susceptible to sudden excitations loadings such as wind gusts, blasts, earthquakes, others which may cause destructive vibration amplitudes lead catastrophic impact on human lives economy. Therefore, various absorbers of linear nonlinear coupling dynamics have been widely studied in plenty publications where some applied real-world practical applica...

Floating offshore wind turbines (FOWT) are subjected to strong loads, mainly due and waves. These disturbances cause undesirable vibrations that affect the structure of these devices, increasing fatigue reducing its energy efficiency. Among others, a possible way enhance performance devices installed in deep waters is combine them with other marine systems, which may, addition, improve stabilit...

Optimum parameters of Tuned Mass Dampers (TMD) are determined in this paper to minimize dynamic response of a multi-storied building system. The response of the structural system is simulated under lateral excitation. To optimize dynamic parameters of the TMD system for minimum top deflection of the structure, a numerical global optimization algorithm called Evolutionary Operation (EVOP) is use...

In this paper a new design for small scale inerter-based dynamic vibration absorber (IDVA) is presented, based upon pivoted-bar mechanism. There are several innovations in study. The first to design, build and test an device that does not need be grounded, or placed between different parts of the structure order create relative motion. Instead, motion created auxiliary mass host structure. Seco...

This paper investigates the use of inerters for vibration suppression of a multistorey building structure. The inerter was proposed as a two-terminal replacement for the mass element, with the property that the applied force is proportional to the relative acceleration across its terminals. It completes the force-current mechanical-electrical network analogy, providing the mechanical equivalent...

Considering the stress cycles in the joints and members due to wave induced forces on offshore platforms, fatigue analysis is therefore one of the most important analyses in the offshore platforms design. Although most of the steel jacket type platforms are designed and located in areas with relatively high ratios of operational sea-states, for maximum environmental events, would have acceptabl...
