A numerical technique is developed using an implicit time‐marching scheme to study the deformation history of steel building frames in fire, by considering the change in the material properties due to rise of temperature, effect of creep and large deformations. A computer program has been developed for the analysis of plane frames based on the above algorithm using incremental and iterative procedures. Based on such a study, the length of time for which the structure can perform its function without either local or overall failure can be predicted.
