| Summary, etc. | This study investigated the impact of shape (square/circle) and transverse reinforcement (ties/spirals) on small-scale concrete columns (1/8th scale) under various loading conditions. The study consisted of two phases, the first phase established individual load capacities, while the second phase explored combined axial load and varying lateral drift subjected to corrosion levels (0%, 15%, 25%). The study found that spiral reinforcement improved the performance under various loading conditions. However, corrosion was unevenly distributed and had a more significant impact on spiral columns. Circular columns with spiral reinforcement were the most optimal design, followed by square columns with spirals. For tied columns, circular columns were again preferable. Based on the results two models were developed to predict the normalized absolute horizontal peak load and the normalized dissipated energy corresponding to specific corrosion level. |
| 520 ## - SUMMARY, ETC. | |
| Summary, etc. | أجريت هذه الدراسة بحثًا يتكون من مرحلتين حول تأثير شكل القطاع (مربع / دائري) وتكوين التسليح العرضي (كانات منفصلة/ حلزونية متصلة) على الأعمدة الخرسانية الصغيرة (بمقياس 1/8) تحت ظروف تحميل مختلفة. حددت المرحلة الأولى مقاومة حمل الضغط المحوري لكل نوع من الأعمدة، بينما في المرحلة الثانية تم اختبار أعمدة الخرسانة المسلحة تحت مستويات مختلفة من صدأ حديد التسليح (0٪، 15٪، 25٪) المعرضة لحمل محوري مع انحراف جانبي متغير. وجدت الدراسة أن التسليح الحلزوني المتصل يحسن الأداء بشكل عام تحت ظروف التحميل المختلفة. ومع ذلك، ثبت أن صدأ حديد التسليح تركز عند فاصل الصب وأن المستويات الأعلى أدت إلى انخفاض أكثر حدة في الأداء، خاصة بالنسبة للأعمدة ذات التسليح الحلزوني المتصل. بشكل عام، ظهرت الأعمدة الدائرية ذات التسليح الحلزوني المتصل كخيار مثالي، يليها الأعمدة المربعة. بالنسبة للأعمدة ذات الكانات المنفصلة، كانت الأعمدة الدائرية مفضلة مرة أخرى. تم تطوير نموذجان للتنبؤ بحمل الذروة الأفقي المطلق والطاقة المبددة المقابلين لمستوى صدأ معين.. |
