Abstract

One of the most recent innovations of high-rise tabular structural system is diagrid structure. Diagrid structural system has been widely applied to high-rise buildings at the last two decades. Diagrid system is predominating other types of tabular structural systems because of its structural efficiency and aesthetic potential. To examine the efficiency of diagrid system as lateral load resisting system, a comparative study on the behavior of diagrid system with framed tube system, has been conducted under earthquake action. Three-dimensional finite element models for a reinforced concrete diagrid building and a concrete framed tube building of 36 stories with similar plan configuration and characteristics were performed. The only variation between the two systems is the exterior lateral load resisting scheme. Dynamic response spectrum analysis was utilized to investigate the dynamic behavior for both diagrid and the framed tube system. Findings which include modal results, lateral story displacements, story drifts, story shears and story moments were presented and discussed. The results revealed that diagrid system is more effective as lateral load resisting structure than the framed tube system with a reduction of 21 % of the consumed materials
 
يعتبر نظام الشبکة القطرية الإنشائي أحد أحدث الأنظمة الإنشائية للمباني العالية وأکثرها أنشارا. يمتاز نظام الشبکة القطرية عن باقي الأنظمة الأنبوبية المشهورة کفائتة الإنشائية للأحمال الجانبية الناتجة من الزلازل أو أحمال الرياح وأيضا بشکله المعماري المتميز. لاختبار کفاءة نظام الشبکة القطرية في تحمل الأحمال الجانية تم عمل دراسة مقارنة بين هذا النظام ونظام الإطار الأنبوبي. تم عمل نمذجة ثلاثية الأبعاد للنظامين بأبعاد متماثلة وبارتفاع 36 دور لکلا النظامين وتم التأثير بحمل ديناميکي (زلزالي). أوضحت النتائج أن نظام الشبکة القطرية أن کفاءته أعلي لمقاومة الحمل الزلزالي من مقاومة نظام الإطار الأنبوبي.
