✦ Synopsis
Computer "re models for simulating compartment "re environments typically require a mathematical formulation that couples the thermal response of the gases that "ll the compartment and the thermal response of compartment partitions. The "re environment characteristics calculated by such models can be used to provide input, via thermal boundary conditions, to an uncoupled thermal-structural computer model for simulating and evaluating the combined thermal/structural performance of the partitions. The objective of such a combined analysis would be to determine, through analysis, the structural "re resistance of a partition design. Depending on the particular partition design of interest, the latter thermal/structural part of the problem would generally require a two-and possibly three-dimensional analysis. As it turns out, there are several quality tools of analysis (e.g., some of those reviewed in Ref. [1]), mainly for non-combustible construction, that are available for use in solving the latter problem. However, because of intense computational requirements, the general use of a multi-dimensional (vs. a one-dimensional) partition thermal analysis in the "re modeling part of the problem is not now practical. A basis is presented for identifying partition designs for which: (1) the use of one-dimensional thermal analysis in the "re modeling part of the problem would lead to reliable simulations of the "re environment, and (2) the resulting simulations can be used to provide the necessary boundary conditions input to solve the thermal/structural part of the problem, using two-or three-dimensional analyses, as required.
