Experimental and theoretical study on seismic behavior of precast exterior UHPC-HSC beam-column connections

open access: yesCase Studies in Construction Materials
This research evaluates the seismic behavior of precast ultra-high performance concrete (UHPC) and high-strength concrete (HSC) beam-column connections. Quasi-static test was performed on three UHPC-HSC connections and one cast-in-place connection.

Acoustic Emission‐Based Evaluation and Mechanistic Analysis of Instability Failure in Concrete Materials

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study presents a quantitative method for assessing concrete damage based on acoustic emission (AE) signal analysis. Employing AE to monitor damage evolution under uniaxial compressive loading in real time. The collected signals were subjected to two‐layer wavelet packet decomposition (WPD) to obtain four frequency bands.

Interface Shear Behavior of UHPC

open access: yesSecond International Interactive Symposium on UHPC, 2019
To date, very little research has been conducted on the interface shear behavior of UHPC-class materials. The structural concrete research group at FHWA’s Turner-Fairbank Highway Research Center is currently developing an experimental program to evaluate the interface shear behavior of this class of materials.
