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

open access: yesGrađevinar, 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

open access: yesBuildings, 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

open access: yesArchives 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 ...

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

open access: yesSakarya 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.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Standardisation of partial strength connections of extended end-plate connections for trapezoid web profiled steel sections [PDF]

open access: yes, 2008
Traditionally, connections are usually classified as pinned or rigid although the actual behaviour is known to fall between these two extreme cases. The use of partial strength or semi-rigid connections has been encouraged by codes and studies on the ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
