Study on Mechanical Behavior of Longitudinal Wet Joints of Prefabricated Assembled Beam

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study investigates the impact of various interface construction techniques on the bending strength of longitudinal wet joints in bridge superstructures through experimentation. A functional relationship between measured bending strength and theoretical shear strength values is established by finite element simulation.

A Two‐Stage GAF‐CNN Anomaly Detection and Conditional Residual Transformer Data Imputation Method for Crack‐Width Monitoring Data

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
In structural health monitoring (SHM), crack‐width measurements are critical indicators of damage severity and serviceability in concrete structures. However, field data are frequently affected by sensor drift, environmental noise, and transmission errors, resulting in anomalous or missing segments that undermine safety assessments.
