The research includes an analytical study using the finite element method for the reinforced concrete beams containing holes in the body. These tested trophies have a rectangular cross-section and without additional armament in the area of the hole,
and two patterns (patterned and simple support) were studied. As for the holes, they are rectangular in shape with variable dimensions, where prizes with one hole and prizes with two holes were chosen.
يستعرض البحث أضرار الانفجارات على المباني والمنشآت الهندسية وآلية توصيف هذه الأضرار ونمذجة المنشآت باستخدام البرامج الحاسوبية لدراسة طرائق الترميم و توقع سلوك المنشأ المتضرر.
يحتوي البحث على دراسة قمنا بها حول تاثير الانفجارات على منشآت البيتون المسح والسلوك الفعلي لهذه المنشآت نتيجة الأضرار الحاصلة.
بالاضافة لعملية تقييم السلوك الحاصل وتوقع المشاكل المستقبلية ودراستها باستخدام النمذجة الرقمية باعتماد برامج النمذجة.
This research paper revolves around studding the repairing of reinforced concrete
columns which are subjected to an axial compression load, by using ferrocement jackets
containing two layers of Welded Wire Meshes (WWMs), which are in turn encapsula
ted in
high strength mortar.
The experiments were carried out at the concrete lab in the faculty of civil engineering,
Damascus University. The results were analyzed in order to determine the effects of
repairing technique on Ultimate Compressive Strength, Ductility of the Column and Failure
Modes. Empirical results confirmed the efficiency of using locally available welded
wire meshes in repairing of reinforced concrete columns.
