Abstract
This research work experimentally investigates an innovative shear walls coupling for enhancement of seismic performance of reinforced concrete structures. The new proposed technique links plane, relatively distant, shear walls with a top roof beam constituting framed-shear walls. An experimental investigation is carried out for five 1/5 scale models. Each model consists of two 100 mm x 600 mm shear walls with 1800 mm height, connected by a 1200 mm long beam at their top with variable depth as a main examined parameter. The depth of top beam ranged from 200 mm to 600 mm. As a complementary to the scope of study, a numerical analysis of the test specimens was carried out using The Applied Element Method (AEM). Both the experimental and analytical results showed reasonable enhancement in strength of coupled shear walls using the proposed technique.
هذا البحث يقدم دراسة وافية عن سلوک الحوائط الخرسانية المسلحة المجاورة لبعض في حال اتصالها عن طريق کمرة ذات جساءة مرتفعة عند سقف اخر دور في المبني و لقد اهتمت الدراسة بمعرفة تاثير هذه الکمرة علي تقليل الازاحة للحوائط و زيادة جسائتها و تحملها للاحمال الجانبية و تغيير شکل العزوم و توزيعها علي الحوائط       و بالتالي تقليل العزوم عند قاعدة الحائط الخرساني . و لقد تمت الدراسة معمليا عن طريق اختبار خمسة عينات مکونين من حائطين متجاورين و تربط بينهم کمرة ذات جساءات مختلفة عن طريق زيادة العمق في کل عينة و تعريض هذه العينات لحمل جانبي بالاضافة الي حمل راسي موزع علي کل حائط.
