Supports in Structures: Support types and Support Reactions

This video explains the meaning of supports when added to structures and shows what are the
different types of supports for beams and frames.
The difference between a roller support, a hinged support and a fixed support is explained.
The video explains why reactions are generated in supports and what are the types of reactions that are generated in each support type.
It shows briefly the principle used for calculating support reactions.

this was very clear and to the point. thank you.

[@drnafie-structuralengineer4620]

I am happy it helped

[@pointless6781]

Very clear explanation, thank you sir. This video will help many students.

[@drnafie-structuralengineer4620]

I am very pleased of that, and I hope I will be able to provide more content to help students.

for a roller support, how is the motion restricted in the x-direction when the applied force is causing pullout of the support?

amazing

Amazing sir

Thank you for the Encouraging Comment

Assuming I am designing a reinforced concrete buildings with 2 or more units attached together. Say I have a continuous supporting floor slab. Are all the supports design as fixed supports? How about a timber building, what type of support will a continuous beam used?

[@drnafie-structuralengineer4620]

The video is mainly concerned with defining the types of supports and how they are handled in elementary structural analysis. What you are asking about is a modeling question.
A continuous slab or beam is supported on columns. Typically, the connection between the beam and the column is neither rigid (fixed) nor hinged, but is something in between. Depending on the properties of the beam and the supporting column, the structural engineer has to decide which option to choose. For example if a concrete beam is supported on a bulky column, then I will go for a fixed connection.
In advanced structural analysis programs you can choose a connection to be semi-rigid.

sir, could you point out the software you used for drawing support symbols?

[@drnafie-structuralengineer4620]

I am using Inkscape. It is a free program.

Better audio!! :)

[@drnafie-structuralengineer4620]

I am pleased it worked out fine.
Meanwhile, for the older videos you can use the closed captions to clarify any unclear voice.
