Comparing Hysteretic Energy and inter-story drift in steel frames with V-saped brace under near and far fault earthquakes

(چکیده مقاله) :
Abstract :

Different rescarches have shown that during destructive carthquakes, most structures cntcr non-reactionary range. Hysteretic Energy, which is wasted after the yield within its hysteresis rings, is very influential on generating structural damage of the system, being the most important component in the equation of the energy, inflicted on the structures. Therefore, controlling this amount of energy leads to controlling the structure behavior. The amount of Hystcrctic Energy in a structure could be an index of its damage level or its malleability. The current paper carries out a nonlinear dynamic analysis on steel buildings with a V-shaped (Chevron) brace, hence survey. ing Hysteretic Energy distribution as well as maximum inter-story drift in the stories of these buildings, under the influence of equalized near and far fault records. Results show that the inter-story drift need for equalized near fault records is more than the far fault ones. Also the results show Hysteretic Energy caused by near fault records that are more than the far fault oncs. What is more, as the building height rises, the share of building's higher stories from the Hysteretic Energy increases. © 2016 Faculty of Engineering, Alexandria University.
