Proceedings of the roof wind uplift testing workshop.

摘要

On November 8--9, 1989, a group of concerned roofing professionals gathered in Oak Ridge, Tennessee, to exchange information and to hear discussions on topics dealing with wind's effect on roofs. Several important issues were addressed: (1) Wind-related roofing problems are a concern to the roofing industry; (2) There is no comprehensive understanding in the US roofing industry of the dynamics of wind phenomena; (3) There is inadequate field data on wind's effect of roof performance; (4) The correlation between field performance and laboratory testing is poor; (5) Procedures for laboratory testing and field testing are inadequate for many roof systems; (6) There is little roof uplift resistance research underway in the US, and what does exist is poorly coordinated; (7) Manuals, test procedures, standards, and codes for wind uplift are often inadequate, even confusion and contradictory at times; and (8) Building owners are not well enough informed to commit to the cost of wind uplift technology development or even to the design and construction of stronger roofs. These concerns led one group, the Single Ply Roofing Institute (SPRI), to commission a study in 1986 to determine the feasibility of an apparatus for testing whole roof assemblies under conditions that closely simulated real roof wind effects. Results from this study were shared with Oak Ridge National Laboratory (ORNL) which has subsequently submitted a review. A major conclusion from the joint talks with ORNL was the importance of avoiding decisions on an individual uplift testing concept with too narrow a focus on wind-related roofing issues. Subsequently, it was decided to schedule a workshop on the topic with the original sponsors being SPRI, ORNL, and the Naval Civil Engineering Laboratories (NCEL). Each document will have a separate abstract.
