مقاومة القص والتورشن في الكمرات

🔸 القص (Shear) بيحصل نتيجة القوى العمودية، وبيتم مقاومته بـ:

🔹 كانات (Stirrups) – رأسية أو مائلة حسب شدة القص.

🔹 أحيانًا بندعّمها بحديد إضافي عند الحواف لو القص عالي.

🔸 التورشن (Torsion) بيحصل لما الكمرة تتعرض لقوة "بتلويها"، وبيتم مقاومته بـ:

🔹 كانات مغلقة بشكل كامل (Closed Stirrups) مع

🔹 حديد طولي إضافي عند الزوايا الأربع للكمرة.

📌 التصميم الجيد لازم يراعي الحالتين لو موجودين سوا

🟨 قاعدة ذهبية للمهندس

الكانات المغلقة + الحديد الطولي عند الزوايا = خط الدفاع الأول ضد القص والتورشن معًا.

👈سؤال للزملاء:

هل واجهت موقف في الموقع اضطريت تعيد تسليح كمرة بسبب تجاهل القص أو التورشن؟ شاركنا 👇
