Expansion joint or not for 200m long concrete building, 3

[hoangvhuy]

Hi everyone,
i am designing structure for a hotel, 12 stories, 200m long. all is reinforce concrete
For normally, we need seperate 3 block by expansion joints, but it makes many difficult problem because architectural design is complicated, non-regular, if building have expansion joint, the joint will seperate the basement,lift core, swimming pool. And impact to facade of hotel.
So, Anybody have experience about same long project, what is best solution?
Can I use post poured strip to deal with that.
Thank for your sharings.

Above is layout of project

You may have to get a little creative... like

and you may have a different pattern on each floor, but the joints should be placed, in particular if it's a high class building. Your architect should provide you with locations of joints in his finished exterior wall system; if he doesn't have them, there could be problems. Joints typically show up on building elevations and are normally required. The joints don't have to be large... 3/4" (20mm) or so...

Another thought... I hope you are not in a high seismic area. We're not, and I missed that because seismic loading and deformation is not undertaken here.

hi @dik
Lucky, this project is in weak( low) - seismic area, don't need calculate seismic resistance

@hoangvhuy
Time to have a sit down with architect and developer as the joints will be required. Architect will have to shift things to accomodate these joints.
How is the ground, is it uniform along the length?

YuleMsee, sums it up, "as the joints will be required."

As noted earlier, "Your architect should provide you with locations of joints in his finished exterior wall system; if he doesn't have them, there could be problems." I'm not trying to be difficult, but with a building with that irregular 'footprint', if you don't have joints, you will likely have serious problems.

hi YuleMsee,
Ground floor is not uniform along the length, and there are 03 level for ground, so, difficult to put in expansion joint.

The cross section poses some other issues. The differences in elevation or building type will require careful location of joints. The building types should be largely isolated. You are looking at some significant joints and the problem is not an easy one. KWhere joints are below grade, they will/should be waterproofed.
