Abstract Building structures are subjected to strong earthquakes, which result in lateral collisions between them. Such often cause severe structural damage and exacerbate the seismic hazard risk of building during earthquake events. This paper discusses application vibration control devices based on negative stiffness inerter damper single-story adjacent structures. The dynamic equations system containing different types under excitation established as a unified model. H2 norm theory Monte...
Energy harvesting from external Ultra-low frequency vibrations is currently attracting a lot of attention. However, for the same system, it difficult to satisfy need more efficient energy in variety environments. Accordingly, an adjustable gearing device connected system used herein adapting wide range The uses four symmetrical inclined springs. One end springs gear and other mass element. geometrical parameters can be varied by rotating gears, thus varying dynamic stiffness system. kinetic...
Vibration control has been of great interest to scientists and engineers for many years. Although linear vibration absorbers have shown be effective in mitigating vibrations at specific frequencies, their reduction effect is usually limited a narrow frequency bandwidth. Nonlinear energy sinks attracted attention due better over wider In practical applications, the nonlinear sink devices can effectively absorb, dissipate, convert from broadband excitation, so as achieve harvesting. However,...
Under the effect of strong earthquakes, collisions or excessive inter-story displacements may occur between adjacent building structures to extent that structure is damaged. The traditional seismic measures for these can no longer meet needs in practical engineering. In this paper, we propose application parallel and serial TID-based control systems buildings as an example a single-story building, use it form new reduction structure. dynamic characteristics design parameter optimization...
Abstract With rapid urbanization, the increasing density of buildings in urban areas has forced us to consider interactions between adjacent structures. However, most studies have focused on fixed foundations, neglecting soil-structure (SSI). This paper addresses this gap by investigating optimization two structures using electromagnetic inerter dampers (EMID) under SSI. The EMID system, equipped with energy harvesting capabilities, was optimized Monte Carlo search method, results...
Abstract Nanopores in 2D membranes like graphene have great potential for applications such as single‐molecule sensing, ion sieving, and harvesting osmotic power. A critical challenge, however, has been to ensure the stability of these nanofluidic transmembrane devices, ultrathin tend delaminate peel away from their substrates when exposed aqueous solutions. In this study, it is shown that using a pyrene‐based coating prevents delamination allows remain freestanding over SiN aperture several...
Prefabricated construction is a state-of-the-art technology of both socio-economic and environmental benefits, but sometimes, it not welcome due to its high cost. Governments play an important role in deeply promoting prefabricated construction, effects are clear. This paper developed system dynamics model for investigating simulating the impacts government incentive strategies on by considering evolutionary game process between contractors. Data Shanghai, China, collected demonstration...
In order to improve the damping capacity of building isolation system, this paper studies control system structure based on negative stiffness. paper, dynamic equation is derived and its parameters are optimized by H2 norm theory Monte Carlo pattern search method. Taking 5-story as an example, analyzes evaluates performance under actual earthquake. The results show that stiffness can traditional system. Additionally, ratio condition stability, smaller ratio, stronger vibration reduction...
Under the action of an earthquake, adjacent building structure will have a large displacement and even cause damage to structure. Structure can be suppressed by adding tuned viscous mass damper (TVMD) negative stiffness amplifier (NSAD) between structures. This paper deduces motion equation structures under earthquake action. The transfer function vibration control system is obtained using Laplace transform. parameter optimization analysis structural carried out through H2 norm theory....
