Keywords: Steel frames, equivalent imperfection
Abstract: Bases of four different conceptions of the equivalent initial tilt utilized in elastic and post-elastic analyses of steel frames are under consideration. It turns out that conception and value of equivalent initial tilt depend on method of analysis and limit state conception. Reduction of initial tilt depending on number of columns per story is motivated if statistically based stationary gaussian random noise model of initial column tilt and bar-disk mechanical model of skeletal structure are applied.
