Fire Resistance Performance of Steel–Polymer Prefabricated Composite Floors Using Standard Fire Tests

Abstract

In this study, the fire resistance performance of steel–polymer prefabricated composite floors, which have a sandwich-type structure, was assessed via standard fire tests and analyzed using finite element analysis. This form of analysis should consider two aspects, namely the thermal and structural fields, so as to simulate complicated material properties and large deformations. As previous studies have already conducted analysis in the thermal field, this study entailed only the structural analysis based on the temperature distributions obtained from the thermal analysis. The variables of the specimens were the thicknesses of the top and bottom steel plates and polymers. According to the analysis results, the top steel plate thickness had no impact on the stability ratings, a criterion for fire resistance performance, whereas the bottom steel plate showed a linear correlation with the stability rating. An equation for the stability rating of composite floors was proposed, and an equation for fire resistance performance was devised based on the insulation ratings, which were obtained from the thermal analysis results.

Experimental investigations of the fire behavior of composites impacted by kerosene/air turbulent flame

“…Numerous standard aerospace evaluations are routinely employed to gauge the ability of materials to withstand fires. [1][2][3][4] These evaluations replicate fire scenarios that materials might encounter and furnish an evaluation of their capacity to endure fires. 5 By using these tests, it is possible to evaluate material performance under different fire conditions and to determine their suitability for use as aircraft components.…”

Seismic Performance of F3D Free-Form Structures Using Small-Scale Shaking Table Tests

“…The Abaqus/CAE 2017 program was used for the analysis and an 8-node solid element was selected. Because the purpose of the analysis was only to validate the small-scale shaking table tests, the mesh size was 60 mm, which was verified by various numerical studies [36][37][38][39]. The UHPC material properties were modeled by the guideline [40] and the Drucker Prager Hardening material model [41], as presented in Table 8.…”

Investigation of the flame properties and fire behavior of carbon‐reinforced PEKK, BMI and phenolic composites impacted by Jet‐A1/air flames

“…Several aerospace standard tests are commonly used to assess the fire resistance of materials. [1][2][3] These tests simulate fire conditions to which materials may be exposed and provide a measurement of their fire performance. The ability of a kerosene burner to produce a controlled flame effectively, safely, and while meeting stringent requirements is referred to as fire performance.…”
