Digital documentation of railway tunnel inspection in Austria

Civil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.
Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Modeling Approaches for Masonry Structures [PDF]

The Open Civil Engineering Journal, 2014
Different scale approaches, micromechanical, multiscale and macromechanical or phenomenological, are presented to study the structural response of masonry elements. First, a micromechanical model is introduced and the masonry is considered to be a heterogeneous material, made of mortar and bricks joined by interfaces, where the mortarbrick decohesion ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Estimating Arias Intensity From Response Spectrum

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Arias intensity serves as a crucial metric to measure ground motion energy and is extensively utilized in earthquake engineering to analyze structural damage, slope instability, and the potential for soil liquefaction. Nevertheless, in many practical design scenarios, only the response spectrum is available, without corresponding information ...
