رد: هل الساب بيصمم ويشيك على torsion للقطاعات ال STEEL ?
السلام عليكم
القطاعات المغلقه ...مثل Pipe or tube
يوجد عليها نوع واحد من Torsion....ما يسمى Pure Tosion
اما القطاعات المفتوحه ...مثل Channel or I-Beam
يوجد عليها نوعين من Tosion .....
Pure Tosion and warping Tosion
للاسف سواء برنامج SAP Or ETABS
يهمل تصميم tosion .....للقطاعات المفتوحه....
نظرا لوجود Warping Tosion....الذى بيتطلب تحليل خاص
او حل يدوى معقد (اى حد ما)
صوره من Manual ...للبرنامج
وهذه صوره من كتاب Steel Structures Design and Behavior 5th Edition
توضح الفرق بين النوعين
