Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections
Structural Concrete, EarlyView.Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

Mechanics‐based model for cold joints in reinforced concrete members
Structural Concrete, EarlyView.Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Mechanical Behavior of Dowel-Type Joints Made of Wood Scrimber Composite [PDF]
Materials, 2016 As a renewable building material with low embodied energy characteristics, wood has gained more and more attention in the green and sustainable building industry. In terms of material resource and physical properties, scrimber composite not only makes full use of fast-growing wood species, but also has better mechanical performance and less inherent ...

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.

Influence of the bonding of rebar dowel with adhesive on wood–concrete composite specimens
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2020 Ensuring the quality of the connector used in wood–concrete composite systems is a critical factor affecting the performance of the system. The main objective of this research was to study the strength and stiffness of wood–concrete composite specimens with two types of rebar dowel connectors: fixed to the wood (solid timber) using epoxy adhesive and ...

Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints
Structural Concrete, EarlyView.Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

Disturbance legacies in arid environments shape recovery of former agricultural land
Restoration Ecology, EarlyView.Abstract Introduction Increasingly, arid agricultural land is being permanently taken out of irrigated production due to more frequent drought, higher temperatures, and the overconsumption of groundwater, with important ramifications for ecological recovery.

Hydrodynamic and ecological effects of engineered logjams: Insights from field observations
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Drone imaging, LSPIV and electrofishing data quantified restoration effects of engineered logjam at the Emme River (Switzerland). Placement and discharge shaped flow: Side jams created longer wakes, centre jams stronger mixing; and lower discharge intensified gap velocities, whereas wake length remained stable.

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.We present ground surface movements on sorted circles in a karst cave using time‐lapse photogrammetry with accuracies of up to ±2 mm. Data with 3‐hourly resolution revealed average vertical movements of up to 50 mm and horizontal movements of up to 15 mm during individual freeze–thaw cycles.

Limnology and Oceanography, Volume 71, Issue 6, June 2026.Abstract Coastal vegetation often grows in spatially distributed patches. However, the influence of individual vegetation patches on small‐scale hydrodynamics has not been well characterized under natural conditions with tidally varying water depths.
