Roof-Top Unit Information No roof-top units on building. The design of structural members supporting roof gravity loads is controlled by the more critical effect of roof live load or roof snow applied in accordance with the governing building code. DESIGN STANDARDS REFERENCED: • AISC Specification for Structural Steel Buildings - Steel Construction Manual, 15th Edition, © 2017. • AISI North-American Specification for the Design of Cold-Formed Steel Structures, © 2016 Edition. • IBC codes are designed in accordance with ASCE7-16 Edition. • MBMA Low Rise Building Systems Manual, Latest Edition. • AWS Latest Edition of Structural Welding Code. • No buyout structural components provided on this project. (RCS,1.0:12) **P m is based on the minimum roof snow load calculated per building code or the contract-specified roof snow load, whichever is greater. This value, P m , is only applied in combination with Dead and Collateral Loads. Roof Snow in other loading conditions is determined per the specified Building Code. ***Ultimate Design wind pressures to be used for wall exterior component and cladding materials not provided by Metal Building Supplier July 7, 2021 A->107'-0"x165'-0"x22'-0"(RCS,1.0:12); B->60'-0"x31'-0"x22'-0" Collateral Dead Wind SeismicSnow Coefficient Snow Load (psf) Professional Seal 09/28/2021
