برنامج لحساب كميات الحفر و الردم ورسم القطاعات



برنامج لحساب كميات الحفر و الردم ورسم القطاعات


يقوم البرنامج بحساب كميات الحفر و الردم ورسم القطاعات بشكل واضح ويمكن استخدامه فى حساب الكميات للطرق أو لمساحة معينة مثل الميزانيات الشبكية.
وعلى هذا فإن البرنامج يحتاج الى أربعة عناصر هامة وهى :
المحطات (stations).
المناسيب التصميمية .
مناسيب الأرض الطبيعية.
المسافات الجانبية أو العرضية لكل قطاع "لكل محطة Station "

تحديد نسبة الاسفلت المثلى للخلطات الاسفلتية


ورقة بحث مهمة جدا اعدت من قبل بعض الباحثين الليبيين بهدف الوصول الى علاقة رياضية بسيطة لتحديد نسبة الاسفلت في الخلطات الاسفلتية

الوصلات


—تم في هذا البحث العمل على إمكانية الحصول على علاقة رياضية بسيطة يمكن من خلالها تحديد نسبة الأسفلت المثلى تقرسيبا وذلك بهدف استخدامها في رصف بعض الطرق والساحات والممرات الغير رئيسية والتي لا تتطلب جودة أو دقة كبيرة في التصميم.

Load and Resistance Factor Design (LRFD) Philosophy


The design of new structures and new elements of rehabilitated bridge structures shall be completed with the use of the AASHTO LRFD Bridge Design Specifications.
The LRFD bridge design philosophy is based on the premise that four Limit States are stipulated to achieve the basic design objectives of constructability, safety and serviceability. All Limit States are given equal importance.
The four Limit States are:
Service Limit State: Stress, deformation and crack width are limited under service conditions
Fatigue and Fracture Limit State: Fatigue stress range is limited for the expected number of stress cycles due to a single design truck in order to control crack initiation and propagation, and to prevent fracture during the design life of the bridge.
Strength Limit State: Strength and stability are provided to resist the significant load combinations that a bridge is expected to experience in its design life.
Extreme Event Limit States: Structures are proportioned to resist collapse due to extreme events, such as, major earthquake, flood, ice flow, collision by a vessel, etc.
Equation 1.3.2.1-1 of the AASHTO LRFD Bridge Design Specifications, unless otherwise specified, must be satisfied for each Limit State:
Equation 1.3.2.1-1 of the AASHTO LRFD Bridge Design Specifications, unless otherwise specified, must be satisfied for each Limit State:
Where η = ηDηRηI 0.95
η = A factor relating to ductility, redundancy and operational importance.
ηD = A factor relating to ductility
ηR = A factor relating to redundancy
ηI = A factor relating to importance
ɤI = Load factor: A statistically based multiplier
ɸ = Resistance Factor: A statistically based multiplier
QI = Force Effect
Rn = Nominal Resistance
Rr = Factored Resistance: ɸ Rn
Subsection 1.3 of the LRFD Specifications may be referred to for additional commentary concerning the philosophy of the Specifications’ development.

الكتاب موجه للمهندسين والفنيين المختصين ويقدم اكثر من 1500 كلمة وعبارة تخصصية في مختلف المجالات الهندسية ويتميز عن غيره بانه لايقدم فقط المصطلحات والمفاهيم اللازمة وانما :
  • يقدم مصطلحات اساسية في جميع المجالات كالاسماء والابعاد والاوصاف 
  • لغة المناقشة وتطبيق المفاهيم الهندسية على سبيل المثال ، الإجهاد والجهد والعمل والقوة ، وديناميكيات السوائل
  • لغة أكثر تحديدًا للهندسة الميكانيكية والكهربائية والمدنية / الإنشائية.

Professional English in Use Engineering presents around 1,500 of the most important technical words and phrases in English that engineers and engineering technicians need
    for their work. The vocabulary has been carefully chosen to include:
      • terms that are essential in all fields of engineering - for example, all engineers need to
        discuss dimensions and tolerances, know the names of common materials, and describe
          how components are fitted and fixed together
            • language for discussing and applying key engineering concepts - for example, stress
              and strain, work and power, and fluid dynamics
                • more specific language for mechanical, electrical and civil/structural engineering.
