CE-3610 Design Basic 2. Material Specifications: 1. The building is to be designed according to the provisions for structural requirement for LRFD for steel as set forth in ASCE 7/IBC. 2.1 2.2 2.3 3. Dead Loads: 3.1 Roof: Light weight Concrete floor over deck ASTM A992 (Gr.50) for all W shape Beams, Girders and Columns Braces HSS (ASTM A500) or W shapes (ASTM A992, Gr.50) 3.1.1 3.1.2 3.1.3 3.1.4 3.1.5 3.1.6 3.1.7 Summer 2022 3.2 Floor: 3.3 Wall: Roofing Materials (Water Proofing etc.) = 4 psf 18" Gage deck = 3 psf Light weight concrete 5 in thick Framing & Fire proofing Suspended ceiling Mechanical & Electrical Solar panels & assembly 3.2.1 Tile including assembly 3.2.2 18" Gage deck 3.2.3 Light weight concrete 6%" 3.2.4 Framing & Fire proofing 3.1.5 Suspended ceiling 3.1.6 Mechanical & Electrical = 8 psf = 4 psf = 4 psf = 9 psf = 9.5 psf = 3 psf Project Part I = 15 psf = 5 psf = 5 psf 3.3.1 3.3.2 Floors require 2 hour fire rating. Live Load considers partition loads as appropriate. 4. The deflection requirements are as follows: 4.1 L/360 due to live load deflection in all interior Beams and Girders 4.2 L/180 due to total load for all spandrel Beams and Girders 5. For Seismic design, the values of spectral response acceleration parameters for the given location should be found using the USGS website Parapets on roof (outer boundary only) = 25 psf (3.5 ft high) Glazed walls (outer boundary only) = 18 psf (ground to roof level) Page 2 of 3
