جذبت الخرسانة فائقة الأداء الاهتمام في المنشآت الهندسية في الآونة الأخيرة حيث أنها ذات مقاومة و صلابة عاليتين.
إن ما يقدمه ال UHPC من مقاطع صغيرة يبرر استخدامه في الأبنية العالية للاستفادة من مقاومته الكبيرة للضغط و الشد .
تم استخدام هذه المادة في الجسور لما تملكه من مقاومة عالية مما يتناسب مع الحمولات الكبيرة و كذلك كمادة صالحة للعوامل الخارجية مما يؤمن ديمومة أكبر للمنشأة . مما برر لنا التفكير في استخدام الخرسانة فائقة الأداء في الأبنية العالية كونها منشآت مكلفة و يلزم الإستفادة منها لأطول فترة ممكنة .
درسنا عدة نماذج من الأبنية متعددة الطوابق و باستخدام الخرسانة فائقة الأداء و تمت مقارنة ما حققته هذه المادة من نتائج في تخفيض الإنتقالات مع نموذج أساسي الخرسانة العادية هي مادة البناء فيه.
و وجدنا بعد التحليل كفاءة عالية لهذه المادة و خاصة في ديافرامات البلاطات .
Ultra-High-performance concrete (UHPC) attracted attention in the civil engineering
industry in recent times, because it has high resistance and rigidity .
What provided the UHPC of skinny clips justifies using it in high buildings to take
advantage of pressure and tensile its resistance .
The largest use of this material in the bridges because of its high resistance which
suitable for large loads as well as a valid treated outside the center and sustainability of the
high buildings, We study several models of building and we use this material in several
elements of these .
We found after analysis of the high efficiency of this models, especially in Diaframat.
