Telling Florida's water story

Article Abstract:

The Florida Aquarium in Tampa, FL, has a roof designed to allow large amounts of natural light yet strong enough to withstand hurricane winds up to 100 mph. Tube trusses were used in the structure due to their strength, aesthetic appeal and cost effectiveness. Lateral resistance and roof stability were addressed through faceted horizontal trusses between the chords of adjacent arched trusses. More than 1,200 precast concrete piles support the aquarium, while the saltwater reservoir rests on a mat foundation reinforced with structured pipe trenches and flexible pipe connections.

Air-supported roof redux

Article Abstract:

The air-supported fabric roofs are much less costly as compared to conventional concrete roofs. The costs for this new type of roof are small due to lower construction costs and an air supported structure. However, this type of roof has some disadvantages such as removal of snow which is difficult and problems also arise from the ponding and deflation while operating expenses are high.These problems can be overcome through design improvements and improved operational management.

Hovering over the harbor

Article Abstract:

The extension of the Convention and Exhibition Center in Hong Kong was built on an artificial island reclaimed with hydraulic sand fill. The center features a sculptured roof made up of six components. It integrates a tube system and six primary steel trusses spanning 27 ft between two core walls. The structure is further supported by secondary trusses stabilizing purlins and the primary trusses against out-of-plane buckling.
