PREFABRICATED CONCRETE HOLLOW CORE SLAB

Hello! I am absolute beginner in STAAD, therefore would like to kindly ask anyone who could share already created .std file with PREFABRICATED CONCRETE HOLLOW CORE SLAB. Dimensions 1200x7450x220 (mm), but in my case just example would be great as well. Already in advance - thank you and a have a great Year 2010!
