Abstract

In last decade,decreasing vulnerability of buildings and life lines due to earthquake is one of the main problem and challenge in Iran.Indeed,when a huge disaster as earthquake happens in metropolitan cities,importance of reducing vulnerability and retrofitting subject bolded.Whereas,most of structures and buildings in Iran are vulnerable and have not evaluated versus major earthquakes,it is necessary that retrofit operations to be performed.Also,majority of constructed buildings in Iran in terms of defect in performance,design and changes in loading codes,especially in Code No.2800 are detected vulnerable.In this research,a five-story reinforced concrete structure with flexural frame according to Code No.2800-Ver.2 designed and with applying Code No.2800-Ver.4 evaluated and performance level based on seismic rehabilitation guidelines calculated.Results showed that structure is weak and with using six method retrofitted.Reinforcement methods are:concrete shear wall,steel centrically brace,reinforced masonry infilled frame,steel buckling restrained brace,viscous damper,and mass damper.Obtained outcomes illustrated that in retrofitted models drift value of roof decreased and performance level closed to safety structural reliability.
