    Anyone know about seismic loading? Looking in your direction civil/structural people!

    I have a very simple concrete slab that is located in a zone 4 seismic zone. The soil report says it not going to see any lateral spreading resulting from liquefaction of the soil as the ground water level is deeper than 60 feet.

    Do i need to still apply a seismic laod to this slab and if i do whats the calculation to use?

    Thanks!

    So I update my own post, I found its not typical practice to account for the seismic acceleration of a foundation slab itself since its attached to the ground and accelerates with it. Makes sense when I thought about it, but not being a structural guy I couldn't be sure. And I don't have the correct code to reference!! :o :rolleyes:

    Houston TX? Try ASCE/SEI 7-05 Minimum design loads for buildings and other structures. Not sure if it's the right one though, as we use British Standards in Ireland. You could also have a look at Eurocode 8.

    You should get them on ihs.com or gigapedia.com

    Thanks for that, the code I am going to is 2006 IBC for California, but the soils report was using an older 1997 UBC code.
    I know maybe silly of me asking here, i am Irish though! Just living in the wild west is all! Do they teach Irish structural eng anything about earthquake loading? Not really a area that you would find many earthquakes

    the ihs.com site looks interesting, do you have a subscription to it at your workplace? How much is it do you know?
