Civil Engineering : Introduction to the Reinforced Concrete Structures
Hamid Sami, PhD 24‘ Princeton University
1,392 students enrolled
English [Auto]
Derive variables used in Reinforced Concrete Elements
Understand the Philosophy of dimensioning Reinforced Concrete Elements
Understand the behavior of Reinforced Concrete based on Reinforcement Ratio
State the Assumptions used in the Design of RC elements
Understand why Steel is used as reinforcing material in concrete

Civil Engineering Courses by Hamid El Darwich:

Learn the language of Reinforced Concrete; You probably have taken Statics and Mechanics of Materials, so this short course will introduce you to the essential concepts that you should know before starting design of concrete elements. 

What to expect from this course:

After completion of this course, you are expected to be able to know the derivation of the variables used in reinforced concrete design such as reinforcement ratio, nominal resistivity of concrete, etc.

In addition, this course guides you through the derivation of these variables. You will also be able to understand the basis of dimensioning of RC elements. 

What are exactly the points covered in this course:

This course focuses on the following concepts:

  • Concrete material and its elements
  • Why does concrete need reinforcement 
  • Why steel is used as reinforcing material 
  • Derivation of RC variables such as effective depth, nominal capacity, etc.
  • Safety factors used in design (most used combination)
  • Assumption used in design 

Students completing the course will have basic knowledge to start design lectures. The course is easy to follow; all of the resources needed are posted in the course content. Other instructors directly start with the design problems making them hard to be understood, this course is your  “Starters”. 

At the end of this section you will learn design philosophy of RC

Reinforced Concrete I : Essentials and Derivations

In this lecture, I introduce to you the information and details about the courses that will be included in the concrete structure series.

This course "Theory of Reinforced Concrete" is the fist course in the series. For sure, it is a pre-requisite for the next courses. Just so that have an idea:

1st Course: Derivations of the Formulas and Theory of Design

2nd Course: Beam Design (T-Beam, Singly and Double Reinforced, Shear Reinforcement)

3rd Course: Slab Design (Solid slab, and Joist Slab).

4th Course: Columns Design (with or without eccentricity)

Introduction to the first Course - The Theory of RC

In this lecture, you will learn:

  1. Definition of reinforced concrete 
  2. What is concrete made of
  3. Why steel is the idea reinforcement 
Whitney's Block : the major assumption in RC Language

In this lecture, you will learn:

- Strain and Strain profiles of RC Section

- Assumptions made in the design of RC Elements

- Derivation of Moment Capacity of RC Section

Critcal Questions

This quiz tests your critical understanding of the steel behavoir in concrete. 

Safety FactorsNominal Resistivity of Concrete

In this lecture, you will learn:

  • Main types of the Loads : DL, and LL 
  • Reduction Factors and the concept behind reduction
  • The main design equation
  • Nominal Resistivity of Concrete Derivation 
Safety Factors Questions

This Quiz tests your understanding of the safety factor and resistivity concepts.

Reinforcement Ratio and Weight of Concrete - Part 1

In this lecture you will learn:

  • Effects of Under and Over Reinforcements

Reinforcement Ratio and Weight of Concrete - Part 2

In this lecture you will learn:

  1. Derivation of values of steel ratio based on the requirements 
  2. Philosophy of putting the boundaries of reinforcement ratio
  3. Tabulated Values of reinforcement ratio 
Understanding Philosophy of Reinforced Concrete

This quiz will test your understanding of the material discussed in this introductory course.

You can view and review the lecture materials indefinitely, like an on-demand channel.
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
