Locking steel floor to concrete walls in seismic zone?
Locking steel floor to concrete walls in seismic zone?
(OP)
Pals
I would like to rigidly connect steel girders to the top of shear walls in a highly seismic zone( peak ground acceleration 0.40g).
Theoretically I guess this is OK, provided I analyse both together and as close to reality as is possible, proportion them accordingly and check some temperature effects too(not significant since floor is insulated and is inside the building).
I will appreciate your final opinion before I make my dive.

You have to make your model matches the design, but you also have to make sure the design is constructable.

What do you mean by "rigidly connect steel giders to shear walls"? Are you trying to make a moment connection or connect shear walls with a steel coupling beam? Or are you trying to drag seismic forces through a steel beam into the shear wall? Are the girders perpendicular or parallel to the shear wall?.....i.e. what is your intent?
What is your roof diapgrahm? Concrete fill or plain metal deck?

By rigidly connecting I meant no sliding. Connection may rotate but no translation.
Walls are simply continuous suppports to my array of beams, I mean shear walls are at the periphery of the floor.
Floor is lightweight concrete deck, but I am not going to rely on the deck for diaphragm action, I am going to heavily brace the floor.
And as ishvaag noted, I am going to anchor the beams with a large factor of safety.
