Fire resistance of aluminium‐glazed partitions depending on their height

“…Comparison of average temperature increase on profile joints (J1-J4) depending on test specimen height (1)(2)(3)(4)(5)(6). E-L, Comparison of average temperature increase on profile joints (J5-J12) depending on test specimen height (1-6).…”

“…E-L, Comparison of average temperature increase on profile joints (J5-J12) depending on test specimen height (1-6). M-P, Comparison of average temperature increase on profile joints (J13-J16) depending on test specimen height (1)(2)(3)(4)(5)(6) wall deflection indicates that, in the early stages of the test, the dominant load is the temperature gradient. Overall, it can be assumed that the bending moment for that load is proportional to:…”

“…6, fire integrity was lost at the end of the 68th minute of the test. In this case, a very interesting mechanism of destruction of F I G U R E 1 0 A-H, Comparison of average temperature increase on the transoms (T1-T8) depending on test specimen height(1)(2)(3)(4)(5)(6). J-L, Comparison of average temperature increase on the transoms (T1-T8) depending on test specimen height(1)(2)(3)(4)(5)(6) the sample element was observed.…”

“…In this case, a very interesting mechanism of destruction of F I G U R E 1 0 A-H, Comparison of average temperature increase on the transoms (T1-T8) depending on test specimen height(1)(2)(3)(4)(5)(6). J-L, Comparison of average temperature increase on the transoms (T1-T8) depending on test specimen height(1)(2)(3)(4)(5)(6) the sample element was observed. The loss of integrity was not caused, as before, by the flame breaking through the small gaps between the mullion and the edge of the glass.…”

“…Partitions with appropriate fire resistance class are usually light walls, whose rigidity is ensured by a steel or timber frame and made of plasterboard for example 1,2 ; they may also be masonry walls made of light small-sized bricks [3][4][5] or sandwich panels. [6][7][8] Despite their excellent parameters in curbing fire, however, these materials are increasingly replaced with more aesthetically pleasing translucent walls (filled with glazing [9][10][11][12] or built of glass brick 13 ).…”
