| چکیده | ||
| از سیستم هایی نوین مقاوم در برابر زلزله می توان به دیوارهای برشی فولادی (SPSW) اشاره کرد. یکی از چالش های مهم دیوارهای برشی فولادی امکان ایجاد بازشو در ورق فولادی می باشد. با این حال ایجاد بازشو، منجر به کاهش سختی، شکل پذیری و مقاومت سازه می شود. در مطالعه حاضر، سیستم باربر جدیدی با در نظر گرفتن بازشو در ورق فولادی و همچنین جهت کنترل کمانش استفاده از مهاربندهای واگرا در لبه بازشو پیشنهاد می گردد. در مدل های پیشنهادی براساس آیین نامه AISC 341، طراحی می شوند و سپس تحت 7 رکورد زلزله نتایج تحلیل های دینامیکی مدل های پیشنهادی با مدل دیوار برشی فولادی بدون بازشو مورد مقایسه قرار می گیرد. نتایج مدل های عددی نشان می دهند که در دیوار برشی فولادی، سهم باربری ورق فولادی برابر 80% و در مدل دارای تیر میانی مابین دو مهاربند(M3)، سهم ورق پرکننده 65% و در مدل دارای تیر میانی سراسری(M2)، سهم ورق پرکننده برابر 30% بار کل جانبی می باشد. در مدل ها با تیر میانی سراسری، ورق های پرکننده وارد مرحله پلاستیک می شوند و تمامی المان های مرزی و بادبندها تقریباً در مرحله الاستیک قرار دارند. همچنین تحت بارگذاری دینامیکی، کاهش یا افزایش ناگهانی به دلیل تسلیم یا گسیختگی ناگهانی المان ها در سیستم پیشنهادی مشاهده نمی شود. | ||

| چکیده [English] | ||
| Steel Plate Shear Walls (SPSW) are modern earthquake-resistant systems. One of the important design challenges of steel shear walls is the possibility of creating an opening in the steel plate. This process decreases the stiffness, ductility, and strength of SPSWs. In the present study, a new bearing system is proposed considering the opening in the steel plate, and controlling the buckling, in the wall using eccentric braces at the edge of the opening. The proposed models are designed in compliance with AISC 341 provisions and then subjected to 7 earthquake records. The results of the dynamic analyses are compared with those of the steel shear wall model without opening. The results of numerical models show that the steel shear wall participates, 80% in load resisting. In the model with a middle beam between two braces (M3), and the model with a central middle beam(M2), the participation of the steel plate is 60% and 30% of the total lateral load, respectively. In the models with the central middle beam, the plate has entered the plastic stage, and all the boundary elements almost remain elastic. Moreover, a sudden decrease or increase due to sudden yielding or failure of elements is not observed in the proposed system under dynamic loading. | ||
