Attachment 2 - Concrete Slab Calculations.pdf

This document is a structural calculations worksheet for a slab design for a 5th wing building, dated 29 Aug 2025, prepared by a USAF Civil Engineer from 99 CES/CENMP at Nellis AFB. The calculations systematically evaluate various structural load components including concrete slab specifications (5000 PSI, 8" thick), steel reinforcement (#4 rebar at 16" o.c.), and building dimensions (48'x78', 15,000 lbs).

The detailed calculations cover dead loads, wind loads, building distributed loads, factor loads, bending moments, and steel reinforcement requirements. Key findings include a wind load of 26 PSF, a distributed building load of 200 PLF, and a bending moment of 6.4 ft-kips. The analysis concludes that while the existing steel reinforcement (0.311 in²) exceeds the minimum required (0.15 in²), the rebar spacing needs adjustment from 16" to 7½" o.c. to meet structural engineering standards. The document is signed by Brent D. Morris, a USAF Civil Engineer, indicating this is a professional structural engineering assessment for a military facility.
