Assessment and Repair of Retractable Stadium Roof Structures

摘要

Perhaps nothing epitomizes the confluence of architecture, structure and machine quite like thernmodern-day retractable roof structure. Part aesthetic statement and part industrial machinery, therndesign of these structures requires a collaborative effort between structural, mechanical andrnelectrical engineers to ensure that the vision of the architect may be achieved by a system that isrnsafe, reliable and maintainable. This paper uses case studies of two existing facilities torndemonstrate the close interaction required between the various engineering disciplines in the designrnof retractable roof systems, and the lessons learned when the disciplines are not well coordinated.rnThese lessons are relevant to future retractable roof stadiums and other multi-purpose facilities asrnowners, architects and engineers strive to make these major facilities more adaptable and thereforernfinancially viable.
