Inverted T or L ledge beams are commonly used in bridges and precast structures. <br/>This study presents a theoretical investigation of the behavior of ledge beams by using the finite element theory to predict the nonlinear behavior of reinforced concrete in all loading stages using ABAQUS software.<br/>Three main variables are investigated in this study namely; the effective thickness of the outer part of the web near the concentrated load where vertical hangers can effectively be placed, the contribution of diagonal bars to the hanging capacity of ledge beams and the effect of the load eccentricity on the hanging capacity of ledge beams. Also, the punching behavior of ledge beams are analyzed using the plasticity-based nonlinear finite element model in ABAQUS. Several experimental results were collected from the literature to support the numerical results. <br/>The study also presents a comparison among the provisions mentioned in the international and local codes to predict the hanging capacity of ledge beams and the punching shear capacity of ledges. Finally, the study presents a proposal for the effective thickness of the outer part of the web near the concentrated load where vertical hangers can be effectively placed. |

| Summary, etc. |
ينتشر إستخدام الكمرات الخرسانيه المسلحه المقلوبة ذات الشفة المحملة في الكباري والمنشأت سابقة التجهيز. يعرض هذا البحث دراسة نظرية لسلوك تلك الكمرات بإستخدام نظرية العناصر المحدودة للتنبؤ بالسلوك الغير خطي للخرسانة المسلحة في مراحل التحميل المختلفة بإستخدام برنامج ABAQUS. تمت دراسة ثلاث متغيرات رئيسية وهي: العرض الفعال من جذع الكمرة بجوار الحمل الذي يمكن وضع الأفرع الداخلية للكانات فيه حتي تساهم في رفع الحمل بشكل فعال⸲ مساهمة الأسياخ القطرية في تحسين قدرة هذه الكمرات علي رفع الحمل كبديل لأفرع الكانات الداخلية و تأثير لامركزية الحمل علي كفاءة هذه الكمرات في رفع الحمل. تم أيضا دراسة قدرة النموذج النظري لتمثيل المادة المتاح ببرنامج ABAQUS علي التنبؤ بقدرة الشفة علي مقاومة القص الثاقب. ويشمل البحث كذلك علي عرض مقارنة بين الإتجاهات المختلفه الموجودة في الكودات العالمية والمحلية والخاصة بالتنبؤ بقدرة الكمرات الخرسانية المسلحة المقلوبة ذات الشفة المحملة علي رفع الحمل وكذلك قدرة الشفة علي مقاومة القص الثاقب. و أخيرا يقدم البحث مقترحا للعرض الفعال من جذع الكمره بجوار الحمل الذي يمكن وضع أفرع الكانات الداخلية فيه حتي تساهم بشكل فعال في رفع الحمل. |
