Finite-element models of the National Fire Research Laboratory (NFRL)and modular support structure



Dat Duthinh


This report documents the development of finite-element models (FEM) of the National Fire Research Laboratory (NFRL) and its modular support structure. The models enable a future user of the NFRL to add a potential test structure and perform thermal and structural simulations of the test. This report serves as a user’s manual for the future NFRL experimenter and consists of two parts. Part 1 covers the NFRL proper, namely the strong floor, strong wall, basement walls and slab. It describes the model and provides results of structural analyses of all the load cases that were specified in the design documents. Part 2 covers the modular support structure, with the various components developed individually, then assembled in an example test case.
