Very informative. Cheers!

Glad it was helpful!

Hi, does it matter if i use the column or the beam as a bearing member since equilibrium loads is on??

[@ideastatica_en]

Hello Pokoto, in general, no. Since the equilibrium is reached, the support is there only to fulfil the completeness of the FEM model (there has to be the support / begin somewhere). www.ideastatica.com/support-center/equilibrium-and-supporting-member However, there might be small differences in case you switch bearing member between e.g. a stiff column and a very weak connected beam - different stiffnesses of memebers maybe affect slightly the overall behaviour of the model. In such cases we encourage the judgement - consider the bearing member as the "strongest" one and avoid choosing the "weakest" one.

I have a very important question that I have received different answers in many places, I would be grateful if you could help. Does the connection at 10.00 transmit moment? This connection is used in truss systems. and it should not transfer moment. but this connection is preferred.

[@ideastatica_en]

Hello Muhammeder, do you mean minute 10:00 of the recording? kzbin.info/www/bejne/nGjIaJujjdBngLc That shows a model of a typical frame corner connection, which is very stiff and is exactly designed to transfer moments between the beam and the column. You can always find out whether your connection should transfer moment or not using the Stiffness analysis, check the blog: www.ideastatica.com/blog/why-bother-with-connection-stiffness

Can you please make tutorial how to make purlin connection seating on this girders with a cleat. I tried but no analysis can be performed.

[@ideastatica_en]

Thank you for your request, @Qamir. We will check the requirement and if possible, we will try to prepare some content on this topic.

I have a question. The reaction on the bearing member would balance the forces. So why do we have to manually input the reaction on the bearing member ?

[@ideastatica_en]

Hello, you are right. For simple models it is as you suppose, you dont have to input the "reactions". But for complex connections where you have continous bearing member with 2 ends, you need to input it unless you get alle the "reactions" added automatically in 1 end only.
