A Shock‐Tube Facility for Gas‐Phase Chemical Kinetics Studies: Design, Validation, and Application for Methane Oxidation

Chemistry–Methods, Volume 6, Issue 1, January 2026.
A high‐pressure shock‐tube facility is developed to investigate high‐temperature chemical‐kinetics for next‐generation combustion systems. The design enables extended test times and integrates multiple optical diagnostics for time‐resolved species detection.

Finite Element Analysis and Verification on Hollow Concrete Filled Double Steel Tube Short Columns Subjected to Axial Load

IOP Conference Series: Earth and Environmental Science, 2019
Abstract In order to study the axial compression behavior of hollow concrete filled double steel tube (HCFST) short columns, the finite element numerical simulation of five existing short columns under axial compression is carried out by ABAQUS.

Confining and hoop stresses in ring-confined thin-walled concrete-filled steel tube columns [PDF]

, 2016
Concrete-filled steel tube (CFST) columns are now widely adopted in many structures due to the superior behaviour provided by composite action. However, this composite action is limited because of the different dilation properties of the constitutive ...

Gradient Boosting‐Based Modeling of Structural Performance in Hybrid Multi‐Tube Columns

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study presents an advanced predictive framework for estimating the ultimate confined strength (fcc,u) and ultimate strain (εcc,u) of a hybrid multi‐tube concrete column (MTCC), an innovative structural system that combines a fiber‐reinforced polymer (FRP) outer tube, inner steel tubes, and void‐filled concrete.

Controlling Meter‐Scale Deformations in Small‐Clearance Tunnels Through Layered Slate Using High‐Tension NPR Anchor Cables: Case Study From Tayi Tunnel

Geofluids, Volume 2026, Issue 1, 2026.
An active control method using negative Poisson′s ratio (NPR) anchor cables is proposed to tackle problems like significant deformations of surrounding rock due to the mutual disturbance between closely spaced twin tunnels in layered slate. Rock mechanics tests indicated a U‐shaped variation in the peak strength of slate across joint dip angles from 0°
