Full-range behaviour of semi-rigid steel connections [PDF]

, 2018
The paper summarises recent research programs undertaken at the University of Sydney on determining the full-range behaviour of steel connections including post-peak softening and fracture. The overall context of this work is to produce models based on the Component Method for the moment-rotation behaviour of joints that are sufficiently simple and ...

Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

SEISMIC ANALYSIS OF FRAMES WITH SEMI-RIGID CONNECTIONS IN ACCORDANCE WITH EC8

Facta Universitatis. Series: Architecture and Civil Engineering, 2020
Up to date research has pointed out that most of the structural connections of reinforced concrete (RC) frames, particularly precast ones, behave as semi-rigid.

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

Advanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Hybrid systems to enhance the seismic performance of steel soft-story structures

Budownictwo i Architektura
Recent global seismic events have shown that most destroyed structures were irregularly designed, especially those with a soft story. A “soft story” refers to a building floor significantly weaker or more flexible than the others, often because of large

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

Advanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Structural Behaviour of Trapezoidal Web Profiled Steel Beam Section using Partial Strength Connection

Electronic Journal of Structural Engineering, 2008
Connections are usually designed as pinned which associated with simple construction or rigid which is associated with continuous construction. However, the actual behaviour falls between these two extreme cases.

Special bi-invariant linear connections on Lie groups and finite dimensional Poisson structures

, 2013
Let $G$ be a connected Lie group and $\mathfrak{g}$ its Lie algebra. We denote by $\nabla^0$ the torsion free bi-invariant linear connection on $G$ given by $\nabla^0_XY=\frac12[X,Y],$ for any left invariant vector fields $X,Y$.

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

An Overview of Progressive Collapse Behavior of Steel Beam-to-Column Connections

Applied Sciences, 2020
Local failure of one or more components due to abnormal loading can induce the progressive collapse of a building structure. In this study, by the aid of available full-scale test results on double-span systems subjected to the middle column loss ...
