if I pinned the column at mid height can I just analyse one part(3.5m) as simply supported? instead of analysing full 7m column, there will be a beam running the mid column and will add bracing. will that be ok? Or if i cantdo that will i have a 7m span with 3 reactions spaced at 3.5m?
thanks for advice I have cone to deflection the only problem is the actual deflection exceeds the assumed deflection when using length=7000mm but when I reduced it to 3500mm the deflection check was ok. so is it okay to use 3500mm assuming effective length for deflection is that incorrect. if I...
I am assuming the column is pinned at both ends and taking the column as a beam for approximate analysis. the length is 7m and I want to take the effective length (3.5m) to reduce buckling, do I use 3.5m length from the start of my calculation from finding reactions, sf, bm and so on.. or only...
is it okay to add axial load to the dead load of steel column with the self weight of steel + cladding. I will need the dead load for the load combination. Any other dead load i am missing?
yes i mean circular hollow section i now know it doesn't experience ltb but im designing a chs beam and want to determine section size to use and bending and shear resistance, I was wondering can i still use the same I beam classification for CHS d/t= cw/t and other equations. the steel data...
Okay, also is it the same beam classification for I beam that I can use for CHS like d/t= cw/tw and other equations for I beam for CHS. Because in the steel data book it mentions I beam is there another databook just for CHS?
for a chs beam do you work out both bending resistance: Mc,y,rd=Wply,Fy/Ymo and lateral torsional buckling = Mb,rd= XltWy(Fy/Ym1). is there a difference or similarity between ltb and bending resistance? or do you use two or one of them in calculation?
Is this the correct way of applying the point loads to a warren truss?

Thanks slide for the links you sent and Jay. i didn't see exactly what I was looking for like diameter and thickness that can be used for bracing, beams and columns small structure. Im looking for were to start so I add load and increase the sizes from there. theres no requirements for choosing...
How do you know the right steel to use in a small structure. for example for a single braced tube (1.5m) what section would be appropriate? what about column of 5m. what about the roof truss members what chs is appropriate? Reason im asking is because i cant find any useful resource online that...
is it possible to have wind direction acting y axis on the portal frame? its normally in the x direction (horizontal to the portal frame. Also instead of the front of the portal frame can it also be analysed from wall side so that the wind y direction becomes x direction?
Can proteus HR rain screen cladding system be installed on a timber frame building? if so does it mean plywood sheet will not be use for wall covering and the Proteus Cladding replace it? will the aluminium supporting be used as a stud in the timber frame to support it?
