Plywood Dome A new, more cost effective structure using age old building materials model GAO STRUCTURE www.gaostructure.com Unit of Plywood Dome Plywood panel fixed on frame members Frame members ( I-Joist) form geodesic curve Creating a Dome Plywood Dome surface Frame Member Advantages of Plywood Dome • Span up to 80 meters in diameter • Simple connection between members • Quadrangular panel requires less work than triangular panel • Panels Less influenced by moisture conditions than wood strips • Material readily available Significant Cost Savings • Up to 50% less cost than reinforced concrete domes • Up to 2/3 less cost than metal frame domes • Up to 30% less cost than other wooden domes What’s the difference ? Plywood Dome Other Wooden Domes Dome surface as a monolithic shell supports load Dome frame supports load Basic design & construction small angle to shape curved surface Plywood Glue and fasteners used for stiff connection Additional support (dome surface) I-Joist Bottom surface when necessary (frame member) Cover Rectangular Roofs Plywood dome Covers central area Steel circular truss Cover 4 corners Cover Buildings of various shapes Best Use of Plywood Dome Cover buildings that • have a large span without interior supporting columns • require low cost roofing • require light weight roofing • require roofing built with sustainable material Applications Material Storage Structures Applications web photo Large Theatres Applications web photo Gymnasiums Applications web photo Movie/TV Production Studios Large buildings with fewer columns Building Plan Column spacing can be 20 – 30 meters.
