- Abstract
- The workers at the Fire Research Station have made significant progress in study of smoke production by diffusion flames and the influence of N2, CO2, and H2O as addatives on the air side. Work on experimental burn out tests has progressed well and preliminary results suggest that the findings may tend to justify rather than discredit the standard time-temperature curve as a basis for fire testing. Elaborate heat flux instrumentation has been involved in these tests with the objective of deriving a heat balance for the fires. Work on thermal decomposition products has not developed well because of staffing problems. The program for study of fire performance of prestressed concrete beams has been initiated. This includes study of the influence of continuity over supports on the behavior of such structures. I saw one of the first of these tests. It appears unlikely that continuity without axial restraint will provide much benefit with respect to fire endurance.
