چکیده

طبق آمار مرکز لرزه نگاری کشوری در سه ماهه اول سال 1398، حدود 2880 زمین لرزه در ایران و نواحی مرزی ثبت و تعیین محل شده است. بزرگترین زمین لرزه ها با بزرگی بین 4 تا 1/5 ریشتر در استان کرمانشاه و حوالی آن رخ داده است. علاوه بر این به طور میانگین در ایران هر 7 سال یک زلزله قوی و دارای خسارت جانی و مالی بالا روی داده است. با توجه به خسارت های ناشی از زلزله، صنعت ساختمان سازی به منظور محافظت بهتر در برابر نیروهای لرزه ای، به سمت سبک سازی و ساخت صنعتی سازه ها پیش رفته است. به همین منظور سازه های سبک فولادی به عنوان یکی از بهترین راهکارهای صنعتی سازی و سبک سازی توسط مهندسین، به کار گرفته شده است. این سیستم نوین ساختمانی در کشورهای پیشرفته با استقبال گسترده مواجه شده است و جایگزین سیستم های سنتی شده است. از این سیستم می توان برای بازسازی در مناطق زلزله زده و ساختمان سازی در مناطق زلزله خیز استفاده کرد. این مطالعه با هدف مروری بر ویژگی های سازه های فولادی سبک برای استفاده در مناطق زلزله خیز و زلزله زده انجام شد.
