Abstract This paper focuses on the optimum design of e-CLT technology. The technology consists in adding cross laminated timber (CLT) walls to an existing reinforced concrete (RC) infilled frame via asymmetric friction connection (AFC). authors carried out quasi-static and nonlinear dynamic analyses. RC is modeled OpenSees by fiber-section-based elements with force-based formulation. contributi...

In recent years, there has been a growing recognition that the rocking motion of structures, especially cylindrical ones, should be evaluated with three-dimensional (3D) models. However, dissipation mechanisms in 3D models are complex and have yet to well established. This paper presents an analytical study on inherent mechanism based rolling friction model external energy dissipators (EDs) for...

Abstract Accurate modeling of material behavior is very critical for the success magnetorheological elastomer-based semi-active control device. The property elastomer sensitive to frequency, magnetic field and input strain. Additionally, these properties are unique a particular combination matrix filler loading. An experimental-based characterization approach costly time consuming as it demands...

A new time-domain probabilistic technique based on hierarchical Bayesian modeling (HBM) framework is proposed for calibration and uncertainty quantification of hysteretic type nonlinearities dynamical systems. Specifically, hyper models are introduced respectively material model parameters as well prediction error variance parameters, aiming to consider both the due unmodeled dynamics. asymptot...

Base-isolated structures achieve superior seismic performance but with the cost of large deformation base floor, which possibly causes superstructure collapse during severe earthquakes. Hence, it is great interest to develop hybrid isolation systems that can reduce and simultaneously improve superstructure’s performance. Recently, several using inerter-based dampers have emerged; however, nonli...

• 1st investigation on the effect of multi-axis seismic excitation bidirectional sliding components. Evaluates ASCE 43-05 and 4-16 nuclear standards for displacement. different intensity measures response During an earthquake, equipment left unanchored in a facility can slide interact with safety-critical systems components, posing safety risk to facility. However, computing especially two dire...

Structures joined by lap-joints can present complex nonlinear dynamic behavior as a function of the stress to which lap-joint is subjected, including contact stiffness variations and softening, along with hysteresis effects related frictional dissipation at interface. Considering applications where use non-parametric models that depend only on input output data required, this work proposes deta...

System identification uses measurements of a dynamic system's input and output to reconstruct mathematical model for that system. These can be mechanical, electrical, physiological, among others. Since most the systems around us exhibit some form nonlinear behavior, system techniques are tools will help gain better understanding our surroundings potentially let improve their performance. One is...
