In this paper, static response and buckling analysis of functionally graded saturated porous beam resting on Winkler elastic foundation is investigated. The beam is modeled using higher-order shear deformation theory in conjunction with Biot constitutive law which has not been surveyed so far. Three different patterns are considered for porosity distribution along the thickness of the beam: 1) ...

Irregular buildings make up a large portion of  urban infrastructure. Presence of irregularities can be due to architectural and  user changes in building stories. Main objective of this article is evaluate seismic performance of structures with vertical irregularities. Seismic responses are obtained by enveloping peak inelastic responses resulting from pushover analyses according to provided p...

With soft robotics being increasingly employed in settings demanding high and controlled contact forces, recent research has demonstrated the use of robots to estimate or intrinsically sense forces without requiring external sensing mechanisms. While this mainly been shown tendon-based continuum manipulators deformable comprising push–pull rod actuation, fluid drives still pose great challenges...

For translinear filters, or log-domain filters, calculation of the maximal signal-to-noise-ratio, an important filter specification, is not trivial, due to the inherent companding behavior and the nonstationary nature of the transistor noise sources. To address this issue, a nonlinear noise analysis method is proposed. Based on large-signal calculations, expressions for the first-order noise an...

During earthquakes, the most prone to damage or collapse are concrete structures. The structure's behavior during earthquakes depends mainly on its shape, size, and geometry. An attempt is made understand seismic response of Underground Rectangular Water tank structure subjected Nonlinear static loading. To predict building structures severe Pushover analysis has been frequently utilized. It ne...

This study presents an effective method based on long short-term memory to reduce the computational cost in nonlinear static analysis of functionally graded plates. Data points representing a load-deflection curve dataset are generated through isogeometric (IGA). The order these data is always maintained as sequential series observations; therefore, it referred time series. Dataset divided into...

Abstract When modeling dynamic structures, the quasi-static modal analysis (QSMA) approach seeks to very accurately resolve force-displacement behavior of each individual mode but neglects coupling, while many other reduced order (ROM) methods take an opposite view, capturing static and coupling using polynomials that limit fidelity with which can be captured. This work contrasts these two appr...

In this paper, damping of interarea oscillations using simultaneous coordination of static Var compensator (SVC) and power system stabilizer (PSS) is considered.  To be effective in damping of oscillations, the best-input signal of power oscillation damper (POD) associated with SVC is selected using Hankel singular values (HSVs), and right-hand plane zeros (RHP-zeros). The 4-machine-2 area...
