Roller supports don't prevent horizontal movements only. They restrain movement perpendicular to their placement. For example, a frame has a horizontal member connected to a wall, and the end condition is roller. In this case, roller support will allow the vertical movement, but it will not allow horizontal movement.
Dear Dr Jawed, Thank you very much for your sharing. Can I ask one please, with pin support resist only Horizontal and Vertical at support and free rotation at support but in reality as steel warehouse I saw most structural Engineers provide pin support to steel column? But in reality the column is not allow to rotate at all? Can you help explain please? 🙏🙏🙏
Having a pin support is a modelling assumption. In reality, all columns and beams will take some moment, but that will be far less than their moment capacity (ability to take moment). In pinned joints or supports, there will always be a gap to allow rotations, but remember rotations will be really very small.
Thank you so much Sir. This was very informative. Which resources would you recommend, I am preparing for my Certificate in Structural Behaviour with IStructE. Thank you

Yes, absolutely right. Roller supports prevent movement in direction normal to their placement. Thanks for the comment.
Always very very Informative
Thanks for kind words.
Thank you Ing.
I'm a civil engineering student,and i would like to continue my advance studies(masters) in your school,how do I get admission?
You can apply here: uel.ac.uk/postgraduate/courses/msc-civil-engineering
Thank you Sir
@@Hanns_designs It is my pleasure!
@@DrJQureshi please can I get your email address, I would like to discuss something with you

@@DrJQureshi Thanks for answering! if you can make a video about it, very helpful junior Engineer like me.

Thanks for kind comments. I recommend using the book, “Understanding Structural Behaviour” by David Brohn. The book is about qualitative analysis.
