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.

چکیده [English]

Nowadays, design of buildings against shock loads caused by explosion has attracted special attention, due to an increase in terrorist attacks. Thus, introducing the nature of explosion and its loads are regarded as the first step in achieving this goal. Blast is an abrupt release of big amounts of energy in which light, heat, sound, shock wave, and dense air are produced. The present study aims to examine the nonlinear dynamic response of a masonry wall including two openings by the underground explosion that employedto produce earthquake -like waves. In this study, Dynamic analysis is conducted through ANSYS software. Menetrey-Willam and Drucker-Prager are used to model the structure and soil, respectively. Finally, the results of analyzing numerical model based on finite element method were compared with the field data. The outcomes demonstratedthat there is good agreement between numerical results and field data.
