چکیده
When an earthquake occurs in a region, it causes structural damages to buildings. Retrofitting these damaged structures before earthquakes to happen reduces the potential hazards and minimizes future casualties. In this paper, the seismic assessment of Reinforced Concrete (RC) structure inadequately to withstand seismic loads due to changing demands, and their retrofitting is studied. After a brief introduction of seismic retrofit described for an existing structure, methods of assessing the seismic vulnerability of existing building is presented. To show the effect of the selected retrofit approach on the seismic behavior of RC buildings, an existing hospital building was selected as the case study. Since the use and occupancy of the selected RC building designed as a residential building had changed, a seismic assessment was carried out using Opensees software to show whether the building needs seismic retrofit or not. For this purpose, nonlinear dynamic analysis of hospital structures under 7 earthquake records concerning Type 2 soil was carried out based on Iranian seismic codes. Besides, to consider uncertainties and structural reliability analysis, 27 earthquake records have been used by the Monte Carlo Sampling (MCS), which results showed that the building needs seismic retrofit because of the increasing demands. In the following, the retrofit approach, which contains using Lead Rubber Bearing (LRB), was performed based on Iranian codes. It is concluded that using this technique of retrofitting and using the reliability analysis method can have a new approach as well as an effective role in improving the seismic behavior of structures.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
