چکیده

اولین اقدام مهندسین پس از وقوع رخداد بحران‌های طبیعی مانند زلزله، ارزیابی اولیه ایمنی و تعیین سطح عملکرد سازه‌ها است. روش‌های موجود ازجمله بررسی‌های چشمی مستعد خطای زیادی هستند. این نوع روش‌ها به سطح دانش، تجربه و قضاوت افراد بستگی دارد. از این‌رو سعی شده است تا از روش­هایی برای کمی­سازی تشخیص خرابی استفاده شود. در هر یک از این روش­ها لازم است تا از یک شاخص برای اندازه‌گیری خرابی استفاده کرد. نکته دیگری که باید در نظر داشت این است که روش­های جدید در علوم رایانه این امکان را ایجاد کرده تا از ابزارهای پردازش تصویر برای اندازه­گیری شاخص­های خرابی استفاده نمود. در این مطالعه پس از بررسی انواع خرابی دیوارهای برشی، معیار عرض ترک به‌عنوان شاخصی برای ارزیابی خرابی معرفی گردیده و با بررسی روش­های پردازش تصویر، روش مناسب برای ارزیابی خرابی دیوارهای برشی ارائه گردیده است. از نتایج این تحقیق می‌توان برای ارزیابی خرابی دیوارهای برشی و تعیین خسارت آن­ها استفاده کرد.

چکیده [English]

After the occurrence of natural disasters such as earthquakes, the engineers' first action is the initial safety assessment and determination of the performance grade of the structures. Existing methods, including eye examinations, are prone to many errors. These types of methods, depend on the level of knowledge, experience, and judgment of individuals. Therefore, attempts have been made to use methods to quantify fault detection. In each of these methods, it is necessary to use an indicator to measure failures. Another point to keep in mind is that new computer science methods have made it possible to use image processing tools to measure breakdown indices. In this study, after examining the types of shear wall failure, the crack width criterion has been introduced as an indicator to evaluate the failure. By examining image processing methods, a suitable method for evaluating shear wall failure has been presented. This study's results can be used to assess the failure of shear walls and determine their damage.
