Experimental and analytical investigations on the effect of steel fibers on the crack behavior and strength of dapped‐end connections

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) dapped‐end connections feature a sharp re‐entrant corner subjected to high stress concentrations, leading to wide cracks under service loads and potential durability issues such as reinforcement corrosion. Effective crack control is therefore essential in the design of new dapped‐end connections. Steel fiber reinforced

Concrete with a very high number of load cycles—Identification of stress levels for efficient investigation of fatigue behavior

Structural Concrete, EarlyView.
Abstract Fatigue stresses are receiving increasing attention in structural engineering, particularly in the design of increasingly slender structures. However, the mechanical response of concrete—particularly its fatigue behavior under very high numbers of load cycles—is still scarcely understood.

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

Structural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns

Structural Concrete, EarlyView.
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

Efficient Approximation Method for Concrete Creep Compliance Function

Yuanzineng kexue jishu
For concrete, the strain tends to grow when the stress is kept at a constant level. This phenomenon is usually referred to as creep. Creep is an important physical property of concrete.
