چکیده

Investigations of past and recent earthquake damage have illustrated that the building structures are vulnerable to severe damage and/or collapse during moderate to strong ground motion. Among the possible structural damages, seismic induced pounding has been commonly observed in several earthquakes. During an earthquake, different seismic behavior of adjacent buildings, causing the collision and impact which are critical loading conditions in comparison with no-collision condition causes. Amount of buildings without construction join, increases the importance of investigating this issue. In order to evaluate the effect of impact force on the seismic performance of RC frame structures, two buildings of 6 and 12 story reinforced concrete frame were selected and their seismic performance under the impact of the collision phenomenon is examined. At first frames were designed in SAP software and then have been modeled in OpenSEES software with different heights, hardness under earthquake records, and were analyzed by a set of nonlinear dynamic time history analysis. Then seismic response of these models is investigated through base shear and roof displacement

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.
