Impact of Failure-surface Parameters of Concrete Damage Plasticity Model on the Behavior of Reinforced Ultra-high Performance Concrete Beams

چکیده
The failure surface of elements can numerically represent by a concrete damage plasticity (CDP) model in Abaqus software which depends on five parameters. parameters are eccentricity, shape, biaxial to uniaxial compressive strength ratio, dilation angle, and viscosity. This paper studies the effect changing values bearing capacity, deflection, overall structural behavior ultra-high performance (UHPC) beams. parameters' changes include reasonable higher or lower than adopted Abaqus. An experimentally performed reinforced UHPC beam is simulated Abaqus, calibrated coincide with practical results. Then, one changed while others remain constant for each alteration study its behavior. numerical analysis results show that all do not affect loading capacity corresponding deflection at first cracking state. At peak state, eccentricity does load deflection. influence shape ratio confined only without affecting capacity. angle appears when it greater 30 degrees 56 degrees, less 30, Rising viscosity value promotes

چکیده انگیزه دلیل اصلی رفتارهای ما است. به نظر می رسد انگیزه جزء جدایی ناپذیر فرایند یادگیری باشد. ارزش ذاتی موفقیت تمایل به پیشرفت را در یادگیرنده ایجاد میکند. به عبارت ساده این تمایل انگیزه پیشرفت نامیده میشود. انگیزه پیشرفت را میتوان در احساس یادگیرنده هنگام چالش با درس های مدرسه، لذت انجام فعالیت درسی، یا حس کشف پاسخ مشاهده کرد.حتی ممکن است انگیزه پیشرفت را در تلاش یادگیرنده برای جلب تایید...
the impact of musical texts on the text recall of young learners of english in isfahan junior high schools
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
