Equilibrium and stability of beams with elastoplastic semi-rigid joints [PDF]

open access: yesArchives of Civil Engineering
The classical theory of beams admits two types of connections between structural elements: perfectly rigid and perfectly flexible. However, the engineering reality calls for a more general approach to joint modelling.

Structural Optimisation and Design of a Cable-Driven Hyper-Redundant Manipulator for Confined Semi-Structured Environments

open access: yesSensors, 2022
Structural optimisation of robotic manipulators is critical for any manipulator used in confined semi-structured environments, such as in agriculture. Many robotic manipulators utilised in semi-structured environments retain the same characteristics and ...

Calculation method of stability bearing capacity of transmission tower angle steel considering semi-rigid constraint

open access: yesCurved and Layered Structures, 2022
The angle steel member is the most commonly used component form of the transmission tower structure. Considering its connection characteristics, we must deal with its stability analysis under semi-rigid constraint conditions for the proper study of the ...

Ipsilateral Rockwood type IV acromioclavicular joint dislocation and midshaft clavicle fracture: a case report and review of the literature

open access: yesJSES Reviews, Reports, and Techniques, 2023
The combination of ipsilateral acromioclavicular joint dislocation and midshaft clavicle fracture is rare. In the last 30 years, only 29 cases have been reported in literature. We present a case of a 55-year-old woman with this combined injury pattern on
