چکیده

امروزه، طراحی ساختمان‌ها در مقابل بارهای ضربه‌ای ناشی از انفجار، به دلیل افزایش حملات تروریستی مورد توجه قرار گرفته ‌است. بنابراین، شناسایی طبیعت انفجار به‌عنوان گام اول در دستیابی به این هدف مورد توجه قرار دارد. انفجار آزاد شدن سریع مقدار زیادی انرژی است که نور، حرارت، صدا و موج ضربه‌ای شامل هوای فشرده را ایجاد می‌کند. هدف مطالعه حاضر بررسی پاسخ دینامیکی غیرخطی دیوار بنایی شامل دو بازشو تحت انفجار زیرسطحی است که تولید امواجی شبیه امواج زلزله کند. سپس نتایج میدانی با نتایج ناشی از مدل‌سازی عددی مقایسه شده است. آنالیز دینامیکی با استفاده از نرم‌افزار ANSYS انجام شده است. سطح تسلیم منتری-ویلیام و دراگر-پراگر به ترتیب برای مدل کردن سازه و خاک استفاده شده است. درنهایت نتایج آنالیز مدل عددی بر اساس روش اجزای محدود با داده‌های میدانی مقایسه شد. مقایسه‌ها نشان داد که سازگاری خوبی بین نتایج عددی و داده‌های میدانی وجود دارد.
