Seismic Weight of Walls
Seismic Weight of Walls
(OP)
I'm running in to a bit of an issue as I prepare for the SE exam. I'm running into conflicting information about seismic weight.
Example: a one story square building, being analyzed the N-S direction. I would have assigned the dead load of the entire roof, plus one half of the weight of all four walls to the diaphragm. However, several example problems I have seen ignore the weight of the walls parallel to the direction of loading (i.e., the east and west walls); they only factor in the weight of the north and south wall. Is this the proper procedure? If so, is there some reference I'm missing?

If you are designing the main lateral resisting system, then all the walls and mass tributary to each level should be included.

Makes perfect sense.
