چکیده
طراحی شمع‌ها شامل عدم قطعیت‌های مختلفی است و رسیدگی به آن‌ها برای اطمینان از ایمنی فونداسیون ضروری است. یکی از رویکردهای رایج برای کاهش عدم قطعیت در طراحی شمع، کالیبراسیون ضریب مقاومت در روش طراحی ضریب بار و مقاومت (LRFD) از طریق تحلیل قابلیت اطمینان است. بااین‌حال، تشخیص این نکته ضروری است که روش LRFD ممکن است به طور کامل عدم قطعیت‌های مربوط به مقاومت نوک و جدار را در نظر نگیرد. این مطالعه نشان می‌دهد که درنظرگرفتن مقاومت نوک و جدار به‌صورت جداگانه می‌تواند منجر به طراحی دقیق و مطمئن شمع‌ها شود. روش پیشنهادی می‌تواند به مهندسان در تصمیم‌گیری آگاهانه‌تر و کاهش عدم قطعیت در طراحی شمع کمک کند. علاوه بر این، این مطالعه اهمیت درنظرگرفتن عوامل مختلف مانند نسبت بار مرده به بار زنده و نسبت مقاومت نوک به جدار در محاسبه ضریب مقاومت را برجسته می‌کند.
