Journal of Field Robotics, EarlyView.ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Trusses, ditrusses, weak trusses
In this paper we extend to left skew trusses $(T,+,\circ,σ)$ previous work on left skew rings. We had presented a left skew ring as a group $(N,+)$ with two binary operations $\circ$ and $\cdot$ with $\circ$ associative, $\cdot$ left distributive over the addition $+$ of the group, and such that the difference of the two operations $\circ$ and $\cdot ...

Simple and detailed modeling of corrosion‐affected slender shear critical RC beams
Structural Concrete, EarlyView.Abstract The corrosion of steel bars compromises both the safety and the serviceability of reinforced concrete (RC) structures. Consequently, reliable tools are required to estimate the detrimental effects of corrosion on the structural response of RC members subjected to transverse loads.

From section to structure: Assessing the impact of localized corrosion on reinforced concrete beams
Structural Concrete, EarlyView.Abstract The structural behavior of reinforced concrete (RC) elements affected by localized corrosion represents a major challenge for ensuring structural safety and for the proper design of strengthening interventions. The effects of localized corrosion on the flexural behavior of RC beams remain a topic of debate within the scientific community.
