vertical seismic loads on released frames
vertical seismic loads on released frames
(OP)
Hi guys
As you know we have to dedicate vertical effect of seismic loads on elements equal to 0.2DL in LRFD method in both directions.
My question is if we want to design and analyze an element with pinned connections like a composite beam in a composite steel deck, should we consider this load effect or no? and what about designing the pined connection ? and what about the slab of composite deck ?
Thanks for your Help [thanks]

Yes sure, we have to combine dead and 0.2*sds*dead
In service life of a pinned member we consider dead+live to calculate deflection of beam, but in design of that beam i think we have to include effect of vertical seismic loads and design it with this combination
Dead+0.2sds*dead+live, i think in real world and when an earthquake occures, it will absorb this loads
Am i true?

When it is required, it should be applied regardless of the end fixity of the member
