چکیده

در سال‌های اخیر استفاده از دیوارهای برشی فولادی به ­عنوان سیستم نوین و مقاوم در برابر بارهای لرزه‌ای رونق گرفته است. یکی از انواع سیستم‌های دیوارهای برشی فولادی، پانل‌های برشی فولادی مهاربندی شده است که از جمله مزایای این سیستم نسبت به دیوارهای برشی بتنی و فولادی، می‌توان به امکان تعیین مکانیسم خرابی با تغییر ابعاد، ایجاد بازشو و اقتصادی بودن آن اشاره کرد. با توجه به امکان استفاده از ورق موج‌دار در پانل‌های برشی فولادی به جای ورق‌های تخت فولادی، در این پژوهش به بررسی اثر وجود تنش‌های پسماند در اثر خم‌‌کاری ورق‌های موج‌دار ذوزنقه‌ای بر عملکرد آن‌ها پرداخته شده است. برای انجام تحلیل‌ها از نرم‌افزار عناصر محدود ABAQUS استفاده شده است. همچنین، شبیه‌سازی فرآیند خم کردن، جهت اعمال اثر تنش پسماند اولیه به ورق پانل، انجام شده است. با مقایسه نتایج تحلیل سیستم‌های با و بدون تنش پسماند، مشخص گردید که تنش پسماند باعث کاهش میزان جذب انرژی، مقاومت، سختی و شکل‌پذیری می‌شود که این کاهش در پارامترهای مختلف به ­میزان 3‌% تا 10‌% متغیر می‌باشد.

چکیده [English]

In the present study, the effect of residual stresses on the performance of braced corrugated steel shear panels (Akbari Hamed and Mofid, 2015a; 2015b; 2015c; 2016; 2017; Amiri et al., 2023) was investigated using numerical modeling, and its results were presented. For this purpose, after validating the finite element modeling method by ABAQUS software, the effect of considering the residual stress on the performance of 12 steel shear panel models with different sizes of sub-panel width, the corrugation angle and the panel thickness was investigated by evaluating some important parameters such as the initial stiffness, the dissipated energy and the strength.
