Description

Welcome to Static Structures - Reactions!

This course consists of a series of light board videos in which I present the theory behind static structures as well as demonstrate plenty of worked examples. On top of this, I will give you questions to test your understanding throughout the course. Solutions to all of these questions are also provided as a resource.

This course should take approximately 4 - 5 hours to complete. Ideally, you would spread this content out over a week, but if you've got an exam or test coming up the very next day, you could smash this course out in one sitting!

This course can be valuable to first year engineering students who want to get a good education on this subject matter as well as industry professionals who are looking to improve or refresh their technical capability.

Who is the target audience?
  • This static structures course is a great introductory course for students at the early stages of their civil/structural engineering degrees as well as professionals who want to refresh their knowledge on the basics

This mini-lecture consists of an introduction of the course creator and lecturer, Mani Risal.

Preview 01:25

In this mini-lecture, we will look at what content this course has to offer and the manner in which it will be taught.

Preview 02:46

In this mini-lecture, we will look at Newton's 2nd Law and how it applies to structures in both force and moment equilibrium.

Newton's 2nd Law
04:52

In this mini-lecture, we will look at reactions and why they are needed to achieve static equilibrium.

Introduction to Reactions
05:07

In this worked example, we will calculate the vertical reactions by using force and moment equilibrium equations.

Example 1
09:43

In this mini-lecture, pin supports and roller supports will be defined.

Pins and Rollers
05:45

In this mini-lecture, we calculate the reactions on a simply supported beam.

Example 2
09:07

Please attempt this question yourself. The solution is provided in the resources folder.

Question 1
00:21

In this worked example, we calculate the reactions on a truss structure.

Example 3
12:53

Please attempt this question yourself. The solution is provided in the resources folder.

Question 2
00:21

In this worked example, we calculate the reactions on a portal frame subjected to uniformly distributed loads.

Example 4 (Introduction to Uniformly Distributed Loads)
07:57

Please attempt this question yourself. The solution is provided in the resources folder.

Question 3
00:21

In this mini-lecture, we will introduce rigid supports and discuss the similarity cantilever beams and poles.

Cantilever Beams and Poles
03:16

In this worked example, we will calculate the reactions for a cantilever beam as well as a pole.

Example 5
10:52

Please attempt this question yourself. The solution is provided in the resources folder.

Question 4
00:21

In this worked example, we calculate the reactions on a simply supported beam with applied moments.

Preview 05:10

Please attempt this question yourself. The solution is provided in the resources folder.

Preview 00:21

In this challenging worked example, we put everything we've learnt in this course so far to the test.

Example 7
11:09

Please attempt this question yourself. The solution is provided in the resources folder.

Question 6
00:21

How can a beam only have points loads subjected to it? Wouldn't there always be a uniformly distributed load due to its own weight?

These questions are answered in this mini-lecture using the theory of superposition.

Theory of Superposition
09:23

In this mini-lecture, we will go through three different categories of structures:

1. Statically Determinant Structures

2. Statically Indeterminant Structures

3. Unstable Structures

We also discuss the fact that the theory covered in this course only allows you to calculate reactions for statically determinant structures.

Preview 09:23

In this mini-lecture, we recap all that we've learnt in this course.
