Analysis of supported steel frames with rigid and semi-rigid connections

Građevinar, 2017
The use of a bracing system for controlling lateral displacement of frames, especially in case of semi-rigid connections, is analysed in the paper. The results indicate that various effects on the stiffness and ductility parameters of structures can be ...

A Design Method for Semi-Rigid Steel Frame via Pre-Established Performance-Based Connection Database

Buildings, 2022
With decades of research, semi-rigid beam-to-column connections have been widely accepted. However, most studies have been restricted to the local connection level, leaving system-oriented analysis and design methods with a meager investigation, which ...

Rectangular Gusset Plate Behaviour in Cold-Formed I-Type Steel Connections

Archives of Civil Engineering, 2017
Cold-formed structure connections utilizing gusset plates are usually semi-rigid. This paper investigates the behaviours of rectangular gusset plates in cold-formed connections of elements whose columns and beams are made with lipped back-to-back C ...

DEFORMATION INDETERMINACY IN GLOBAL ANALYSIS OF STEEL STRUCTURES WITH SEMI-RIGID JOINTS

Facta Universitatis. Series: Architecture and Civil Engineering, 2020
This paper shows the procedure for determination of deformation indeterminacy within global analysis of steel constructions with semi-rigid joints, as well as the analysis of deformation indeterminacy within the approximate deformation method.

A Numerical Investigation of the Influence of Semi-Rigid Composite Connections on the Seismic Behavior of a Building with Steel Concentrically Braced Frames

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
Semi-rigid composite connections are connections which have a certain rotational stiffness and bending strength by means of the slab and its reinforcement.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

Advanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips

Advanced Functional Materials, EarlyView.
This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...
