Shaft walls...best practice?

[FWSchreck]

Hello:

Please help settle a debate: Which is the best practice, in terms of performance, for modelling a shaft enclosure?

(1) A series of walls, extending the full height of the shaft (multiple floors)
(2) A series of walls, extending floor to floor, locked to a reference plane
(3) A series of walls, extending floor to floor, unconstrained
(4) Each shaft enclosure is a group, extending one floor only

1. then us the shaft opening tool to cut the hole and make sure you pick extend into core.

We look at a case by case because shafts rarely stay the same size and shape as they go up through floors. However we would attempt to keep the walls single across as many floors as possible. If you must break walls always constrain the top and bottem to allow for level adjsustment.

IMO, modeling for performance sometimes has to come second. How is it going to be built? If it is going to be constructed as one wall going all the way up then model it that way. Floor to floor, then model it that way. If floor to floor I would constrain it to the levels.

How it is to be constructed needs to accurate so that sections and details jive with real world conditions.

But you take the slab to the core face of the the shaft wall, then join geometery and it looks like its floor to floor with the shaft liner passing by.
