Abstract    Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Different performance of bearing walls in past earthquakes, motivates investigation on the adequacy of current seismic design provision for these walls. This study considers seismic performance of model walls of bearing wall system and building frame system designed as ordinary and special shear walls. Performance of the model walls are evaluated through static pushover and incremental dynamic analyses. Results show the superior performance of bearing wall system, which shows justification for possible increase in the response modification factor of this sytsem in the design codes.


Keywords    Bearing wall system, Building frame system, Special shear wall, Ordinary shear wall, Incremental dynamic analysis


چکیده    دیوارهای سازه­ای معمولا به عنوان اجزایی کارا برای بارهای جانبی و قائم مورد استفاده قرار می­گیرند. عملکردهای متفاوت دیوارهای باربر در زلزله­های گذشته، لزوم بررسی ایمنی دیوارهای طراحی شده براساس ضوابط آیین­نامه­های طراحی را در پی دارد. در این مطالعه عملکرد دیوارهای سیستم دیوار باربر و سیستم قاب ساختمانی طراحی شده براساس ضوابط شکل­پذیری ویژه و معمولی مورد بررسی قرار گرفته است. عملکرد دیوارهای مورد مطالعه با استفاده از آنالیز استاتیکی و دینامیکی افزاینده مورد بررسی قرار گرفته است. نتایج گویای عملکرد بهتر سیستم دیوار باربر است که با ضرایب رفتار پائین­تر این سیستم در آئین­نامه­های طراحی همخوانی ندارد.
