The influence of secondary reinforcement on a strut‐and‐tie model for the design of reinforced concrete corbels

open access: yesStructural Concrete, EarlyView.
Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

Flexural behavior of precast prestressed slabs with embedded building service systems

open access: yesStructural Concrete, EarlyView.
Abstract Dry‐assembled precast concrete construction is rapidly spreading in many parts of the world due to the several advantages offered by industrialized construction. In order to speed up not only the assemblage of the structure, but also the full integrated building process, engineering systems (mechanical–electrical–plumbing) may be prefabricated

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

open access: yesStructural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

open access: yesStructural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

Pesticides and Hypospadias in Southern Brazil: An Ecological Study

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Rio Grande do Sul ranks among the Brazilian states with the highest pesticide consumption and one of the highest prevalences of hypospadias, a congenital anomaly often associated with prenatal exposure to endocrine‐disrupting chemicals. We assessed the relationship between prenatal pesticide exposure and hypospadias risk through an ecological ...

Tree cover and geographic origin of tree species drive bird functional groups in urban environments

open access: yesWildlife Biology, EarlyView.
Urban trees provide habitat and resources for wild species in cities and support biodiversity provision of ecosystem services, among which insect control is particularly relevant. Predators of insects are promoted by the presence of trees and, in turn, may enhance biosecurity of the trees.

Factors influencing wintering turfgrass field use in Atlantic brant

open access: yesWildlife Biology, EarlyView.
Atlantic brant Branta bernicla hrota increasingly use turfgrass fields, such as baseball fields and golf courses, throughout their wintering range. Most studies have focused on their primary food source, submerged aquatic vegetation, while studies of other goose species worldwide have examined field use in different contexts, including agricultural ...
