چکیده

پس از کشف آتش و تغییرات شگرف آن در زندگی بشر، آتش­سوزی به عنوان یک خطر بزرگ همواره جان و مال مردم را تهدید می­کرد. در این پژوهش به بررسی و شبیه­سازی عددی آتش­سوزی با استفاده از نرم­افزار FDS در یک کتابخانه عمومی پرداخته ­شده و با ایجاد تغییراتی در معماری ساختمان به صورتی که بتواند بر زیبایی معماری و کارایی بنا اثر گذاشته و علاوه بر آن به کاهش سرعت گسترش آتش و افزایش ایمنی کتابخانه نیزکمک شود و ضمنا از بخش با ارزش مخزن کتاب نیز محافظت شود. به همین منظور ابتدا به بررسی تاثیر درب­های ورودی بر گسترش آتش پرداخته ­شده و با استفاده از درب­های اتوماتیک، تاثیر قابل توجهی در کنترل جریان باد ورودی به داخل کتابخانه حاصل شد. در ادامه با ایجاد قسمتی اصلاحی، تلاش برای محافظت از بخش ارزش در برابر نفوذ آتش شده است و در نتیجه این تغییرات علاوه بر افزایش زیبایی کتابخانه از منظر معماری، بعد از گذشت یک دقیقه دما در قسمت مخزن کتاب­ها نسبت به وضعیت قبل از اصلاح، 16 درصد کاهش پیدا کرده است.
