Hysteretic Behavior of Moment-Resisting Frames Considering Slab Restraint and Framing Action

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Hammad El Jisr

This paper examines the influence of framing action and slab continuity on the hysteretic behavior of composite steel moment-resisting frames (MRFs) by means of high-fidelity continuum finite-element (CFE) analyses of two-bay subsystems and typical crucifo ...

Soft Biomimetic Fish Robot Made of Dielectric Elastomer Actuators

Dario Floreano, Herbert Shea, Jun Shintake, Vito Cacucciolo

This article presents the design, fabrication, and characterization of a soft biomimetic robotic fish based on dielectric elastomer actuators (DEAs) that swims by body and/or caudal fin (BCF) propulsion. BCF is a promising locomotion mechanism that potenti ...

Influence of Load Duration on Shear Strength of Reinforced Concrete Members

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

The significance of sustained loading on the compressive and tensile strength of concrete has been experimentally verified since the 1950s and is currently acknowledged in most design codes implicitly or explicitly. However; its influence on other potentia ...

Experimental Evaluation and Numerical Modeling of Wide-Flange Steel Columns Subjected to Constant and Variable Axial Load Coupled with Lateral Drift Demands

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper presents results from an experimental evaluation on the pre- and post-buckling behavior of 12 steel wide-flange cantilever columns under axial load and lateral drift demands. The influence of several loading and geometric parameters, including t ...

Ultralong, complexly structured micro- and nanoscale metallic glasses and fibers

Grégoire Courtine, Fabien Sorin, Wei Yan, Inès Richard

The present invention and its embodiments propose a simple, unique, and scalable method for producing extremely long, highly uniform, and well-ordered micro- and nanoscale metallic glasses via thermal drawing the method comprising at least the steps of pre ...

X-Shells: A new class of deployable beam structures

Mark Pauly, Florin Isvoranu, Mina Konakovic Lukovic, Francis Julian Panetta, Etienne Bouleau

We present X-shells, a new class of deployable structures formed by an ensemble of elastically deforming beams coupled through rotational joints. An X-shell can be assembled conveniently in a flat configuration from standard elastic beam elements and then ...

Seismic Stability of Wide-Flange Steel Columns Interacting with Embedded Column Base Connections

Dimitrios Lignos, Hiroyuki Inamasu

The rotational flexibility of column base connections is commonly assumed to be detrimental to the seismic response of steel moment-resisting frames (MRFs) because it increases story drift demands and promotes soft-story formation by lowering the point of ...

Temporal upscaling in micromagnetism via heterogeneous multiscale methods

Doghonay Arjmand

We consider a multiscale strategy addressing the disparate scales in the Landau-Lifschitz equations in micromagnetism. At the microscopic scale, the dynamics of magnetic moments are driven by a high frequency field. On the macroscopic scale we are interest ...

Full-Scale Testing of Deep Wide-Flange Steel Columns under Multiaxis Cyclic Loading: Loading Sequence, Boundary Effects, and Lateral Stability Bracing Force Demands

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper discusses the findings from 10 full-scale steel column tests subjected to multiaxis cyclic loading. The columns use deep wide-flange cross sections typically seen in steel moment-resisting frames designed in seismic regions. The effects of bound ...

Patterns of Carbon Nanotubes by Flow-Directed Deposition on Substrates with Architectured Topographies

Pedro Miguel Nunes Pereira de Almeida Reis

We develop and perform continuum mechanics simulations of carbon nanotube (CNT) deployment directed by a combination of surface topography and rarefied gas flow. We employ the discrete elastic rods method to model the deposition of CNT as a slender elastic ...
