I'm designing a portal frame structure similar to third type on the picture.
Mine also has a horizontal tension element (a tie) at the level of knee joint (column-beam) connecting both columns. Knee joint is not glued but has to be mechanically connected. Base connection to the foundation is also rigid because my frame is quite high and I need it to stiffen it against lateral deformation.
My question is what kind of knee joint would you design. I'm considering a system with self-tapping screws in tension like ZD-Platte or glued in metal sheets like HSK-System.
I cannot use double beam or column.
How do you usually design a rigid connection? With bolts? For that you usually need to make the wooden members bigger to make it work and still stiffness stays an issue.
I am currently undertaking the structural design for a 5-storey multi-residential wood structure. I am working with a student architect who is keen on using CLT panel construction (I am a student myself).
Having done my research I have found some very good information on this type of construction i.e. span tables and case studies etc, however it is proving difficult to find any good info for structural/material properties for the CLT panel material, does anyone know of anywhere that this kind of info is readily available i.e. manufacturers technical details etc...
Any help would be much appreciated, cheers,
Bearing capacity of steel plate, F2ax.Rk EC5, 8.5.2(2)
F2ax.Rk = 3.fc.90.kÂ·π/4*(dw^2-(d+1)^2)
My question is why I need to use compressive strength of wood and not plate?
My connection look like steel - timber - steel, my washer is working against steel and not wood?
Thanks in advance.
