In this course, I will explain the full and detailed process of designing a reinforced concrete rectangular section for bending as per ultimate strength design method with step by step approach and requirements of AS3600 which is the Australian standard for concrete design.

What you’ll learn

- Different design conditions of concrete beam design and assumptions as per Ultimate Strength Theory.
- Concrete beam design as per ultimate strength method for a balanced beam.
- How to check if tensile reinforcement in a concrete beam is at yield.
- How to check if compressive reinforcement in a concrete beam is at yield.
- AS3600 requirements for the maximum neutral axis ratio , ku and minimum reinforcement capacity reduction factor for concrete beams , Flexural strength (modulus of rupture) and minimum strength requirement for a concrete beam.
- Concrete beams design as per ultimate strength method for a ductile concrete section (under-reinforced beam).
- Concept of the minimum height of the concrete beam.
- Reinforced Concrete beam design step by step.

Course Content

- Introduction –> 10 lectures • 1hr 7min.

Requirements

- Strength of materials course in university.
- Basic mathematics.
- Our two other courses “Reinforced Concrete Beam Analysis Part I” and “Reinforced Concrete Beam Analysis Part II” are very beneficial to understand the basics of ultimate strength design..

In this course, I will explain the full and detailed process of designing a reinforced concrete rectangular section for bending as per ultimate strength design method with step by step approach and requirements of AS3600 which is the Australian standard for concrete design.

I will start with a summary of different ultimate design conditions of concrete beam and assumptions as per ultimate strength design theory and them will explain concrete beams design for a balanced beam, also I will explain how we can check if tensile reinforcement and compressive reinforcement in a concrete beam section is at yield or not.

Also, we will go through the important requirements of AS3600 such as maximum neutral axis depth ratio, minimum reinforcement, and capacity reduction factor for concrete beams.

In the next step, we will look at the concrete beam design as per the ultimate strength method for a ductile concrete section or under-reinforced beam followed by some important code requirements:

· Concept of the minimum height of the concrete beam

· Flexural strength (modulus of rupture)

· Minimum strength requirement for a concrete beam

Finally, I will explain the step by step design of a reinforced concrete beam as per the ultimate strength design method and to understand the full process we will have three examples of a beam design to cover different levels of loading to design the beam and how to calculate the tensile and compressive reinforcement

Working example 1: Design of a reinforced concrete beam with minimum reinforcement as per ultimate strength design method

Working example 2: Design of a reinforced concrete beam as per ultimate strength design method with reinforcement larger than minimum reinforcement and no compressive reinforcement and calculating the minimum height of the beam

Working example 3: Design of a reinforced concrete beam with compressive reinforcement as per ultimate strength design method and calculating the minimum height of the concrete beam which does not require any compressive reinforcement.

By the end of this course, you will learn the full and detailed process of designing a reinforced concrete rectangular section for bending as per the ultimate strength design method and requirements of AS3600 which is Australian standard.

My goal is to add value to my students by conveying my knowledge and explaining the theoretical concept behind the design, so please do not hesitate to ask if you ask any questions through the message box here or any other social media links which are provided in our page.
