Remedies to Thermal Radiation in Fused Silica Optical Fibers

open access: yesJournal of Telecommunications and Information Technology, 2023
During fire incidents, optical fibers located with-in a fire-resistant cable are usually exposed to temperatures of 800◦C to 1000◦C. Hot fibers generate narrowband thermal (incandescent) radiation and collect broadband thermal radiation originating from

Review of Fire Tests on Seats for Passenger Coaches and the Materials Used in Them

open access: yesFire
This study shows how the fire regulations for railway seats used in international traffic have changed over the last 30 years. In the past, a paper cushion was used as a flame source, and today, a 15 kW burner is used; consequently, the requirements have

Fire Behavior of U-shaped Steel Beams Filled with Demolished Concrete Lumps and Fresh Concrete

open access: yesApplied Sciences, 2018
To reuse waste concrete in a more straightforward and simplified way, a new kind of structural member containing fresh concrete (FC) and demolished concrete lumps (DCLs) distinctly larger than conventional recycled aggregates has been proposed.

Research on the Scale Fire Test and Fire Resistance of the One-Way Slab of a Metro

open access: yesBuildings
To address the difficulty in conducting fire tests to verify the fire-resistance limit of large one-way slabs with heavy loads in a metro, a scale fire test method is proposed based on the bearing capacity calculation of the one-way slab under fire.
