Precast cladding panel connection suggestion?

[Inszz]

Client wants to have this kind of precast cladding panel on the external as below. As you can see, the panel will run at a degree to the column below.
I haven't come up with a solution especially the movement connection.
Can anyone share his idea? Thanks.

PROPOSAL=
- PRECAST INCLINED PANEL IS CASTED WİTH TRIANGULAR BRACKETS THK.200 mm.
- PROVIDE 4 EA'S ANCHOR HOLES AT SLAB
- THE PC ELEMENT WILL BE INSTALLED AND SUPPORTED WİTH ANCHOR BARS . USE ADJUSTMENT NUTS AND SUPPORTING SHIM PLATE
- THEN GROUT THE HOLE .

Thank you very much for your proposal. Not sure if I misunderstand anything but looks like you are connecting the triangular 'panels' instead of the inclined ones to slab? Or do you mean the included ones and the triangular one comes as a whole and then reply the triangular ones to connect to the slab on top?
One more question is how do you deal with the movement connection for the horizontal story drift?
I redrawed the elevation as below, maybe this one is a bit better.

Much appreciated if you can explain to me a bit further. Thank you very much

the triangular 'panels' ( shown with blue color thk 200 mm etc) is cast together with inclined slab. That is, each inclined slab included two triangular panels..

I do not understand the depth ( 0.5-3m )..

Regarding the horizontal story drift.. will you post the structural plan and predicted story drift? I have suggested hanging of the inclined PC element to the slab. What is the conn. detail for the above PC panels?

 

[Inszz]

Thanks for your quick reply.

0.5-3m means that the depth varies. (There are many inclined panels like this and their 'depth' are not the same)

The story drift will be within 35mm under seismic. For the panels above I have bearing connection (cast-in plate in panels) at the bottom to slab and movement connection (EA) at top.
I will post the plan when I get to the office tmr. Thank you very much.

On the incline panel, if the over-hang is constant at 2m and the height varies from 0.5m to 3m it would seem that these panel are twisted which is going to be very hard to cast. It would take a special adjustable bed that could be twisted as required and I have never seen or heard of anything like that.
From a casting standpoint, it would be far better to pick an incline angle for all panels. If that cannot be done, maybe the incline panel should be made from something that can be twisted to fit rather than using concrete which must be cast to fit.

I am not sure of the building size, but I would be careful about this being precast depending on the sequencing. A client of ours did a number of small precast fill in pieces for a small tower, and it was a nightmare since the slab crew just went ahead with their business. Installing the little pieces was a terrible job, and once it was complete it was pointless given the other options to achieve the same look.

Plan find plan below. Column spacing to be 4m.

I'd tend to think some sort of steel subframe fixed between column and underside of slab would be the go to option here (maybe a triangular shaped frame made of channel or angles, fixed to the face of the columns so the columns take the weight of the panels). Just fix to the inclined panels via some cast in weld plates to which cleats could be site welded to suit given the tolerances involved with the complex geometry. Since the panels do not go between storeys the drift the connections need to accommodate would be minimal?

Thanks for all the insights.

Clients wants concrete all around even for triangular ones. That said, if the triangular part can be steel frame, I still cannot picture what cast-in plate in inclined panel to cleats is like here. Can you maybe elaborate?
For the story drift, since the column will drift as well, don't we need to consider the movement connection as well. Also, I forgot the mention that the story height at this level is 3m, which means there are panels that just 'drop' to the floor level.

Same for the movement consideration, at upper floor, client wants to form this L shape panel (see the red circle below) as a whole instead of having two separated panels (these panels are vertical not inclined). Is this doable in regards to movement connection?

Thank you.

Dear Inszz (Structural),

Will you post a perspective of the inclined panel ? Apparently , the triangular panel depth is 0.5 m and inclined panel depth is variable 0.5 to 3.0 m.. and the depth 3.0 is at mid point between the columns.. Is this true ?

Could the use of GFRC panel with light steel frame be an option?

 

[Inszz]

Thanks for your response, HTURKAK.

As you can see from the plan above, we have multiple sets of inclined panels. So different inclined panel has different 'height' and the triangular one just change to suit. Please see the pic below.
