G'day,
Well I've come up against a problem that doesn't seem to have a direct answer.
I am designing a steel SHS column to support a concrete tilt panel wall (laterally). The wall is supported at the top by timber trusses and bracing and at the base by the standard dowel and pad footing setup.
I have followed the Australian Standard (AS4100) for assessing steel properties under fire conditions and have determined by the method given that the member will survive for about 15 minutes before reaching it's limiting temperature (440 deg. C) and begin to fail. This is easy enough, however I would now like to apply a suitable treatment to increase the fire rating to 180 minutes as required by the building code of Australia. The column is located at the corner of the room and can be fully enclosed without any problem.
Can anyone point me to an on-line site that can offer readily available solutions. I would also be interested in a bit of technical info on fire effects on steel.
regards
sc
