خلاصه مقاله:
Steel braces hasve a growing application in building structural and industrialconstructions. In the recent years there has been a lot of research done aboutperformance and behavior of these types of structures in elastic and plastic stateswhos outcomes have been effective on improvement of design criteria andimplementation quality of structures. On the other hand since near fault seisms havedifferent properties from those of far fault seisms and issues related to effects of nearand far fault have been recently separated in different regulations, seismic behaviorof steel constructions designed on the basis of lateral load resisting concentratedbracing system and regulation of designing resisting constructions to seism (StandardNo. 800-3rd edition) has been studied in this research. Frames studied are of 5, 10 and15-floor structues from which one frame has been selected to be studied and timehistory non-linear dynamic analysis method and effects of two types of near and farfault accelerogram have been used. Values of displacement and floors reverse anchorand base shear in both modified (with scale) and unmodified (without scale) states ofnear and far fault accelerograms were calculated and the results were compared.
