Analysis of the rigid joints of steel sheet screwed under the effect of heat

One of the members of the special structural steel beam to column joint area . Rigid joints in steel moment frames have a special role in the behavior of structures under fire resistance of these joints can be important . In this joint the behavior of rigid steel sheet coil coating under heat using numerical finite element method and using Abaqus software is evaluated. The model used an experimental model of the elastic and plastic through to the validation failure and the numerical results , the effect of large deformation nonlinear area is considered. The results of this study indicate that the connection with the cover sheet is very sensitive to heat so that the heat increases exponentially with decreasing resistance as well.
