Atrium-Architecture Basis • sunlight through the atrium is collected like rain in a lake in the mountains • sunlight flows through the trusses into rooms • atrium trusses are like trees on the mountain AEC

Atrium-Truss System AEC

Atrium-Truss Selection Three-Hinged Arch Truss • Problems • deflection • complex connections AEC

Atrium-Truss Constraints • Architectural height constraints • Repeated glass panel size, 4‘x 5‘ • Stability of half-truss 2. 3’ 8’ span 4’ span height 30’ elev 20’ span between trusses 40’ base AEC

Atrium-Truss Details • Anchor connection to slab • Bolt connection • Purlin detail • Column connection, no slab AEC

Atrium-Member Sizes • Truss members 2 L 4 x 4 x 1/4 • Bolts A 325 N ¾“ diameter • Purlins 2 L 3 x 5 x 1/2 • Columns W 10 x 100 AEC

Learning Experience-What did we learn here • Computer • Necessity • Communication New hardware & software • Be Clear & Listen • Collaboration Meltdown flexibility Asynchronous vs. Synchronous • 1 Goal. Down • Breaking Discipline Lines Create clear. Team sketches • Act as one AEC
