Mr. Ben Zhou served as the lead structural engineer for this design/build aircraft maintenance hangar project for the US Navy. The project featured a precast folded plate arch roof structure spanning 75 meters and designed to resist typhoon wind and high seismic loads. This structural system, taking advantage of the most efficient structural form and load path, has realized significant savings in concrete and reinforcing steel in comparison to traditional design for cast-in-situ construction. For this long span roof, the concrete is equivalent to only a 200 mm (8″) thick solid slab thanks to the folded plate design concept.
Precast made this structural system possible by casting the folded plate arch segments on the ground , then lifted off ground and joined in the air.
Project received the ASCE (Hawaii Section) Outstanding Civil Engineering Achievement Award in 2006.
