| Summary, etc. | This study investigates the effect of circular openings on the structural performance of post-<br/>tensioned (PT) slabs, commonly used in modern construction for their superior load-bearing <br/>capacity and ability to span long distances with reduced depth. A finite element model was <br/>developed using RAM CONCEPT software to analyze 72 PT slabs, varying in tendon <br/>arrangements, circular opening sizes, and positions. The impact of these openings on slab deflection <br/>and stress under different loading conditions was examined. Results show that circular openings <br/>increased maximum deflection by less than 5%, and tension stress levels ranged from -20% to <br/>+56%, depending on the opening location and tendon layout. The findings provide valuable insights <br/>for engineers and designers, offering practical guidance on the effects of circular openings in PT <br/>slabs, which are compared by international code provisions. |
| 520 #3 - SUMMARY, ETC. | |
| Summary, etc. | تعد البلاطات الخرسانية لاحقة الشد من أهم النظم الإنشائية في الوقت الحالي نظرا لسرعتها في عملية البناء وفاعليتها في البحور الكبيرة و تقليل سمك الأسقف . يهدف البحث إلى دراسة سلوك هذه البلاطات من حيث الإجهادات والترخيم تأثرا بعدة متغيرات و تشمل وجود فتحة بأقطار مختلفة و نسبة إلى طول البحر ( 1/8 , 1/4 , 1/2 ) مع تغيير مكان هذه الفتحة (Field Strip - Column Strip - Column Zone ) و استخدام نظامين لوضع الكابلات (Distributed-Distributed , Distributed-Banded) و دراسة ذلك في حالة إضافة أحمال ميكانيكية مع تطبيق كل هذه المتغيرات على بلاطات ذات بحور مستمرة و بلاطات كابولية . وقد أثبتت الدراسة ان زيادة قطر الفتحة يزيد الإجهادات في بعض مواقع الفتحات عن الأخرى و فاعلية الفتحات الصغيرة لنظام وضع الكابلات DB للتوفير في قطع الكابلات كما أثبتت ان لم يتأثر ترخيم البلاطات ذات الفتحات وظل أقل من حدود الكود المسموح به في الأكواد العالمية وهذا يثبت فعالية استخدام نظام لاحق الشد لتقليل الهبوط وان وضع حمل ميكانيكي إضافي يبلغ 10 كيلو نيوتن/م2 بالقرب من الفتحة على البلاطة الخرسانية كان له تأثير طفيف على الإجهادات. |
