Thank you for your reply.
It's requested by the architect for a project in Africa.
He needs external stairs to be used only in case of emergency and leave enough space for acces below.
Hello everyone,
Can someone help me designing drop down fire escape stairs please ?
It would help a lot if you can share some structural details.
Thank you
Thank you for your reply.
Yes.
Not only in the middle. We are reinforcing it because we are using it to support a new monorail load.
Can we use a fillet weld at the end intead ? Is there another reason to provide more bolts if one is enough for the load transfer ?
Thank you again !
Thank you again,
If I understood your idea, you mean if for example we are adding a 50 KN concentrated load on the beam, we consider 25 KN as a shear load on the bolt, and if it is a 10KN/m we condier 10x0.3=3KN on the bolt ?
I have no experience in wood design.
That's what I think too...
Hi Everyone,
We are reinforcing a corroded existing W16x36 with two centred C12x30 channels.
I would like your opinion on how to determine the efforts on the connection bolts and their spacing as the shear flow is null. I detemined the maximum force from the stress on the half top of the...
Thank you for your reply, I really appreciate.
But how can we be sure the loads are fully transmitted to the channels and the bolts are resisting ? Is there a way to calculate the efforts on the bolts using the pressure on the channels from the bending moment ? and how to distribute it on the...

I found it in two calculation notes. I couldn't find any code or guide talking about. I think we can remove it and considerate only the bottom flange is resisting the lateral bending moment. No torsion will then be taken into account.
