The Pier Luigi Nervi's concrete structure of Palazzetto dello Sport: Modeling and dynamic characterization

Structural Concrete, EarlyView.
Abstract This paper presents a numerical and experimental study aimed at the modeling and dynamic characterization of the reinforced concrete structure of the Palazzetto dello Sport in Rome, designed and by Pier Luigi Nervi with Annibale Vitellozzi, and built by Nervi & Bartoli contractors in 1956‐57.

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Moment‐curvature behavior of continuous reinforced concrete slab strips—Experimental determination and modeling

Structural Concrete, EarlyView.
Abstract With the market introduction of new reinforcing materials, such as corrosion‐resistant steel, the effect of their stress–strain relationship on the ductility of reinforced concrete structures needs to be evaluated. Their moment‐curvature behavior significantly influences bending moment redistributions, rotation capacity, and deformation at ...

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

Electronic Modulation of Cobalt Single‐Atom Catalysts via In‐Plane and Axial Coordination Engineering for Enhanced H2O2 Electrosynthesis

SusMat, EarlyView.
Symmetry‐breaking in‐plane and axial coordination modulates the electronic structure of cobalt single‐atom catalysts for selective two‐electron oxygen reduction (2e− ORR). In‐plane O coordination (Co–N2O2) strengthens *OOH binding and suppresses activity, whereas axially coordinated Co–N5 enriches the Co center and optimizes the dz2 orbital, weakening ...

LamelODF: a MATLAB‐based toolbox for orientation distribution analysis and mapping of lamellar minerals for laboratory and synchrotron X‐ray diffractometers

Journal of Applied Crystallography, EarlyView.
LamelODF is a MATLAB‐based toolbox aimed at simplifying the automated extraction of orientation distribution functions from 2D X‐ray diffraction data of lamellar minerals in transmission mode. It accommodates both laboratory and synchrotron data formats, providing an integrated pipeline from raw data to spatially resolved textural maps, enabling robust

Bandwagon effects in a floral market: Early pollinator acquisition offsets colour disadvantages in less attractive flowers

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with striking colours or scents are often considered to have an advantage in the competition for pollinators. However, if pollinators copy others to avoid exploration costs in changing environments, less attractive flowers may benefit from acquiring early ...
