Utilization of numerical techniques to predict the thermal behavior of wood column subjected to fire part C: Sensitivity analysis

Theoretical studies have been carried out to predict the fire resistance of different configuration of wood columns as done in Part A and Part B of this set of research papers. This theoretical study is a continuation of previous studies, which were carried out at National Research Council Canada. M...
