Structural Design of Metal Prestressed Shell Structure"THE FUKUOKA EXIBITION HALL"

Abstract

The roof frame of THE FUKUOKA EXIBITION HALL that images sea waves is composed by the large scaled steel latiticed vault and the steel trussed ribs which strengthen the vaulted shell and are utilized as maintenance roots and mechanical uses. Prestressing forces has been introduced to the edge beams of the steel vault to reduce vertical displacement. The designmethods for the metal prestressing shell structure adopted here, the effect of prestressing and the steel trussed ribs, and so on are presented in this paper.
