The Study of Energy Acceptance for Rigid Connections with Numerical Methods

Abstract eng:
Generally we can use the members of extra internal strength with rigid connections. In this case, whenever a point is over loaded, another distribution happens in the length of the member for extra stresses. With applying to this connections , negative moment that is created in the fulcrum , reduces the affirmative moment which is placed in the middle of the mouth and because of this the section surface that is needed , decreases and so it economics the amount of steel. Rigid connection is the best type of connection among all types of beam to column connections that the only problem with it is the weakness and difficulty in executing it, however, about this connection there were not a lot studies or at most it is limited in appointing the stiffness or shear and moment in the region of connection. Therefore in this paper we have tried to make use of numerical methods (e.g. finite elements) in modeling this connection that is a minute and efficient method and recently according to the increase in speed and efficiency of high speed computers has been in vague. And finally, one of the important features of this connection is, energy ductility will be considered with this method and by using available plans.
