Pressure–impulse diagrams of RC beams considering fire–blast interaction
Structural Concrete, Volume 26, Issue 3, Page 3305-3318, June 2025.Abstract When analyzing military, defense, or structures/infrastructures deemed critical, explosion‐induced actions—often associated with malicious actions—play a significant role. The combined effect of a blast and fire is not uncommon: in fact, an explosion can be the extreme consequence of a fire or vice versa, a fire can occur as the result of an ...

Engineering Reports, Volume 7, Issue 4, April 2025.A one‐dimensional representation of an initially damaged conductor cable is subject to mechanical tension, heat exchange with the environment, and an electric current, which combined lead to thermal failure from overheating. The deterministic solution of the physical system through the finite element method enters the PCM stochastic solver as a black ...

Connections of Trapezoidal Sheets under Fire
Acta Polytechnica, 2009 This paper describes two different experiments on connections of trapezoidal sheets under elevated temperatures. The first experiments were tensile tests carried out on four sets of tests with screwed connections under ambient and elevated temperatures ...

Multi‐Scenario Stochastic Modeling of Failure in Power Transmission Lines
The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.This paper presents a comprehensive thermo‐electro‐mechanical model to investigate the effect of unexpected high wind, wildfire, and ice on power transmission lines over time. The developed method offers an in‐depth perspective on temperature and damage evolution within the power lines by incorporating a damage and fatigue phase field model, with ...

Component‐Based Modeling of Steel–Concrete Composite Endplate Connections Under Fire Conditions
Advances in Civil Engineering, Volume 2025, Issue 1, 2025.In fire scenarios, the performance of connections in composite structures differs significantly from that in noncomposite steel structures. To accurately simulate the high‐temperature behavior of composite endplate connections, a component‐based model has been developed and integrated into the Vulcan software.

Model Tests on Influence Factors on the Pullout Behavior of Suction Caisson in Stratified Soils
Advances in Civil Engineering, Volume 2025, Issue 1, 2025.As offshore wind power constructions expand into deep waters, suction caissons have gradually become the preferred foundation. The controlled load of the suction caisson for the deep‐water wind turbine is the pullout load. A series of experimental tests have been conducted focusing on various factors influencing the pullout bearing capacity, including ...
