5) and Blanc's model (Eq. 7). It is noted that most of the existing numerical models for gas transport in the static chamber were developed based on Blanc's law (Perera et al. 2002; Senevirathna et al. 2007; Bian et al. 2020, 2021; Ng et al. 2015). However, Blanc's model may be only valid for investigating the multi-component gas …

A sectional view of the considered test building is illustrated in Figure 1. The structure has an overall height of 16.4 m, the inner radius of the dome is 5.37 m and the cylinder wall has a thickness of 0.325 m. The bottom part of the structure is fixed, gallery and buttresses are incorporated into the system.
