چکیده

مطالعات عددی و آزمایشگاهی انجام شده بر روی دیوار برشی فولادی و همچنین عملکرد آن در زلزله های گذشته موید یک سیستم کارا در برابر بارهای جانبی است. این سیستم دارای شکل پذیری، سختی و مقاومت بالایی است. هر چند تاکنون مطالعات زیادی بر روی این سیستم انجام شده است اما همچنان ناشناخته های زیادی در خصوص آن وجود دارد. در میان این ناشناخته ها، تاثیر ترک بر رفتار سیستم با توجه به تحقیقات کم در این زمینه کاملا مشهود است که تاثیر قابل ملاحظه ای بر روی رفتار این سیستم دارد. بنابراین در این مقاله، تاثیر ترک های میانی و کناری و گسترش آنها بر رفتار لرزه ای دیوار برشی فولادی مورد بررسی قرار گرفته است. نتایج نشان می دهد که ترکهای میانی ورق فولادی اثر مخرب تری نسبت به ترکهای کناری دارد. ترک های میانی با طول زیاد باعث می شود که سیستم در ناحیه الاستیک گسیخته شود همچنین گسترش ترک تاثیر کمی بر سختی الاستیک دارد. علاوه بر آن، ضرایب رفتار دیوار برشی فولادی با وجود ترک ارائه شده است. همچنین برای دست یابی به نمودار بار-تغییر مکان یک مدل پارامتریک ارائه شده که بدون استفاده از مدل سازی المان محدود به نمودار بار-تغییر مکان دست یافت. در این مدل، اثر ترک و همچنین گسترش آن لحاظ خواهد شد.

چکیده [English]

Experimental and numerical study have carried out on behavior of Steel Plate Shear Wall (SPSW) and also, its good performance during past earthquakes have been testified a capable system against lateral load. The system have high ductility, stiffness and strength under seismic loading during a sever earthquake. Although, enormous studies have been performed till now, there are several unkhown problems about this system. Effect of crack on SPSW behavior is obviously one of the important between the unkhowns that have considerable effect on the behavior of SPSW. Therefore, in this study the effect of crack on SPSW is investigated. Results indicated that central crack is more critical than edge cracks. The results show that long central cracks cause the system fails in a brittle manner. In addition, a model have been proposed to obtain load-displacement curve without finite element modeling. On the proposed model the crack and its propagation is consider.
