I am currently just working out the preliminary. I tend to treat them as separate diaphragms using joints (although here in Australia no much consideration is given to earthquake and I don't think it is popular here to use seismic joints). Even if they work as a one diaphragm, the structure will...
This structure is actually part of the building, There is stair and elevator core but it is on the other side. What happens here is the architect cut two big rectangle out of the building at the middle to get lights. So it looks like a I shape building. And as the connection between these two...
It is a real case in Australia. It is 3m high x 14m long I have checked the code and couldn't find anything regarding whether this kind of structure is forbidden or not but I have never designed it this way and am not comfortable with it. There are not walls on both sides because they are both...
May I ask why out-of-plane stiffness need to be modified? I can understand in most cases normally we modify them to avoid massive reinforcement and under earthquake we allow the wall to crack but in this case, do we really need to or can we really modify them? The out-of-plane capacity is the...
Hi msquared48, yes with the internal columns it is. However I am more concerned about using the out-of-plane capacity of the wall so the structure here I am talking about is actually using wall out-of-plane capacity alone without internal columns. One thing I find this structure dangerous is...
This is a 6 storey building. The walls (200mm thick) run in x directions only. Due to the architectural layout, no shear walls can be arranged in y direction, I might add some internal columns between walls for gravity supports. All floors are flat slab.
My question is, can we reply the...
