Cantilever Roof Structural Failure Caused by Excessive Construction Loads, Flawed Design, and Poor Maintenance
A busy shopping center department store was suddenly brought to a standstill because of the collapse of the structural roof support system. This paper will explore the reasons leading up to the collapse. Those reasons include overloading the roof structural support system during re-roofing operations, design errors within the building structure, construction errors, and lack of maintenance of the building structure. Various roof loading conditions assumed during the re-roofing operations will be analyzed with the assistance of a computer structural analysis program. A torsional analysis will also be performed to determine if the structure collapsed by way of torsional overturning under load. Other modes of failure investigated were lateral buckling, web crippling and sidesway web buckling. The paper concludes that the structure failed due to under-designed cantilever beams, no weak axis bracing, excessive welding of joists to structural beams, poor maintenance of the building roof, and poor supervision of the Roofing Contractor.
