Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This paper presents a gradient‐based optimization framework for the preliminary seismic design of alternative isolation systems and fluid viscous dampers in vertically irregular 2D shear frames. The proposed method simultaneously optimizes the number, locations, and properties of isolation layers together with viscous damper coefficients ...

Optimal Seismic Design of High‐Rise Buildings With Outrigger Tuned Inertial Mass Damper
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This paper presents a novel optimization method for designing a system with a tuned inertial mass electromagnetic transducer (TIMET) damped outrigger (DO) for high‐rise buildings subjected to earthquakes. The DO system consists of the TIMET devices, which attach vertically between the outrigger and the perimeter columns.

Attitude analysis in Flatland: The plane truth [PDF]
Many results in attitude analysis are still meaningful when the attitude is restricted to rotations about a single axis. Such a picture corresponds to attitude analysis in the Euclidean plane.

Space‐Time Modeling and Numerical Simulations of Non‐Newtonian Fluids Using Internal Variables
International Journal for Numerical Methods in Fluids, EarlyView.Based on Hamilton's principle, the study focuses on a novel strategy for the modeling of non‐Newtonian fluids with the help of internal variables. Here, the viscosity evolves locally in space and time. Three configurations are numerically implemented, namely channel flow, a benchmark, and a lid‐driven cavity.

International Journal for Numerical Methods in Fluids, EarlyView.In this paper, we consider the concept of discretely divergence‐free finite elements (DDFFE) based on the Rannacher–Turek finite element pair to efficiently solve the three‐dimensional incompressible Navier–Stokes equations. For this purpose, we first define a spanning set of DDFFE functions and then characterize a set of basis functions for arbitrary ...

On the Integral Representation of Jacobi Polynomials
MathematicsIn this paper, we present a new integral representation for the Jacobi polynomials that follows from Koornwinder’s representation by introducing a suitable new form of Euler’s formula.

A generalized Euler-Maclaurin formula on triangles
Journal of Computational and Applied Mathematics, 1998 This paper provides a short proof of the existence of an asymptotic expansion for a composite integration rule for an integral over a triangle. The expansion is an expansion in even powers of the discretization parameter \(h\) for a uniform subdivision of the triangle, whenever the integration rule has degree at least zero, and the integrand is ...

On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion
International Journal for Numerical Methods in Fluids, EarlyView.Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.
