Correction: Xie et al. Investigating Fire Collapse Early Warning Systems for Portal Frames. Buildings 2025, 15, 296

References

Insert the reference “Ji, W.; Li, G.; Lou, G. Early-Warning Methods for Fire-Induced Collapse of Single Span Steel Portal Frames. J. Constr. Steel Res. 2022, 190, 107154.” in the original reference list and mark them as [23]. With this correction, the order of some references has been adjusted accordingly.

Missing Citation

In the original publication [1], “Early-warning methods for fire-induced collapse of single span steel portal frames” [23] was not cited.

References [9,23] are added in the first paragraph on page 4 as follows: The geometric size is shown in Figure 1. The basic dimensions of the main and secondary components are shown in Table 1 [9,23].

Above Figure 3, on page 6, the sentence “The deformation at the typical position of the portal frame is shown in Figure 3” is replaced with “Ji [9,23] proposed a deformation of the typical position of the portal frame, as shown in Figure 3”.

The first line on page 11, “Four common collapse modes of portal frames are summarized in Figure 10”, is changed to “Ji [9,23] proposed four collapse modes for four portal frames, as shown in Figure 10”.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
