Stair wall subject to lateral load
Stair wall subject to lateral load
(OP)
Hi
I am modelling a 6 storey building using Etab (21m high). I modelled the stair walls and core walls using wall pier and spandrel around the openings to take vertical and lateral load (wind and earth).
Please see the attachment for the load applied on the wall pier at Level 1. The moment from earth load (91KNm) is quite high for pier (250mm wide x 150mm thick).
Heavy reinforcement must be used in this pier.
My question:
Any thing wrong in the way I modelled and give this load to the wall pier ? This load is reasonable ? If yes, then use heavy reinforcement in this pier.
Thanks

But the pier I mentioned has a small cross section because the opening is too close to one side (It is the stair way not elevator). I look like that I have to use a steel I-section inside the concrete pier (composite column) to resist high bending moment.
