In this study, structural analyses were conducted to analyze the performance of a bridge which friction pendulum systems (FPSs) applied using different models. A Coulomb model and rate dependent constructed coefficient PVDF/MgO material effect analysis The uses single regardless velocity, while can reflect change in with velocity.

Abstract The mainshock of the 2016 Kumamoto Earthquake (Mw 7.0) caused extensive damage to buildings in downtown Mashiki, Prefecture, Japan. heavy building area was associated with both strong ground motion and response characteristics. Fortunately, there were two stations observed records during distributed, showing peak velocities exceeding 100 cm/s on surface. level shaking would be sufficie...

Formulation of governing equations for an elastic cable have a long and dated history. A unified framework to detect the dynamics such systems is detailed, justified, assessed numerically. Modal analyses are performed in Frenet basis, which describes motion local frame accounts accurately system’s physics. In this article, methodology produce arbitrary reduced-order models nonlinear provided. T...

performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (vce) could be considered as one of the main causes of bridges collapse. in most of bridge design codes, for seismic analysis of bridges, vce is not taken into account or a distinguished method isn’t presented for assessment of vce. in the present work, the effect of vce on two existing...

Equivalent linearization is an available method widely used to conveniently predict the nonlinear responses of buildings. The present study proposes a seismic response prediction based on equivalent stud-type viscoelastic dampers with amplitude dependencies for that there not lot research discussing estimation such dampers. Through analyses, authors found proposed leads structural design proces...

evolving models have found applications in many real world systems. in this paper, potentials of the evolving linear models (elms) in tracking control design for nonlinear variable structure systems are introduced. at first, an elm is introduced as a dynamic single input, single output (siso) linear model whose parameters as well as dynamic orders of input and output signals can change through ...
