106x70x35 Edwards AFB Big Top As-Built.pdf

This document is a set of engineering drawings for a tensioned fabric structure (shelter truss system) manufactured by Big Top Manufacturing Inc. The drawings depict a curved truss frame structure measuring 106 feet long by 70 feet wide by 35 feet high, designed to span large open areas with minimal internal supports.

The structural system comprises double 2.375" x 0.095" steel truss chords with yield strength of 55,000 PSI and tensile strength of 60,000 PSI, connected by 1.90" x 0.090" Z-bar chords. The structure incorporates lateral bracing between trusses using 3/8" x 4.5" galvanized Grade 5 nuts and bolts, with junction plates measuring 5/8" thick Grade 50 steel. The design includes ridge poles, X-braces for lateral stability, cable bracing systems (both roof and wall cables), and a fabric cover in white (8028 color, 28 oz weight). Anchor details specify concrete wedge anchors and base plate configurations for both inside and outside chords. The drawings provide comprehensive details on truss section connections, lateral bracing locations, cable attachment points, base plate dimensions, fabric tensioning methods, and component specifications necessary for complete fabrication and installation of the temporary shelter structure. All engineering is noted as proprietary to Big Top Manufacturing Inc., located in Perry, Florida.
