Abstract AR
تعرض هذه الورقة طريقة عددية مبسطة للتحليل اللاخطي للمباني العالية (المستوية أو في الفراغ) و المعرضة لأحمال رأسية و أفقية.
الطريقة هي تطوير لطريقة نقل العزوم و طريقة نقل العزوم و القوى.
الطريقتان مشتقتان من طرق توزيع العزوم و قد استخدمتا بنجاح في التحميل الخطي للمباني العالية مع تجاهل أو الأخذ في الاعتبار التشوهات المحورية في الأعضاء الرأسية.
أدمجت اللاخطية في التحميل، بعدم تجاهل العالقة بين العزوم و القوى المحورية في الأعضاء الرأسية في وجود إزاحات جانبية كبيرة.
استخدمت الطريقة المقترحة لدراسة مسائل مختلفة، و قد قورنت النتائج المتحصل عميها بنتائج بين النتائج يؤكد دقة الطريقة حصل عميها باستخدام طرق العناصر المحددة القياسية.
و قد أثبتت المقارنة أن هنالك توافقا جيدا المقترحة.
Abstract EN
In this paper, a simplified numerical method of global and local second order P-Delta 2D and 3D analysis of tall buildings subjected to vertical and horizontal loads is presented.
The method was based on developing the moment transformation (MT) and the moment-force transformation (MFT) methods those are formulated using the moment distribution methods and have been successfully used in linear analysis of tall buildings neglecting and/or taking into account axial deformation in vertical members.
The method was developed to include second order effects, by coupling the axial force and the bending moments in each of the vertical members with large lateral displacements at floor levels.
Validity of the method was established by comparing the results of two 2D and 3D problems with those resulted from a reliable finite element approach.
The comparisons show that, the results are in good agreement thus verifying the accuracy of the proposed method
