چکیده
The current study presents the effect of geometric parameters such as horizontal curvature, and columnheight on the seismic response and fragility of curved multi-frame concrete box girder bridges. The model is usedto perform a set of nonlinear time history analyses for a ground motion suite to compute the fragility function ofcomponents and system. Moreover, multiple levels of each geometric parameter are determined to identified theeffect of geometry. As-built bridge models are modified by varying one of each parameter and the modified modelsare repeatedly simulated for the seismic fragility assessment. Component damage levels are explored for joint seals,columns, bearings, abutments, unseating of decks, foundations, and shear keys, and system level damage statesconsistent with HAZUS-MH definitions. Median value modification factors are proposed to scale fragility curves toaccount for the deck radius effects. the column height is the most influence parameter affecting the system fragilitywhile the horizontal curvature and abutment skew have a relatively minimal influence on the system fragility of thisclass of bridges.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.
