 MEETING AGENDA

OBJECTIVE

REVIEW OF OBJECTIVES WILL INCLUDE THE FOLLOWING:  Description of issue, discussion by TAC, public comment, TAC action

1:00 P.M.

 1)

Welcome and Opening, Roll Call

Reviewed and Approved of the July 14, 2014 Meeting Agenda
Reviewed and Approved the June 24, 2014 Minutes.

2)

 

Full scale wind load testing of aluminum screen enclosures ( Project # 4 )

 

The TAC heard a presentation from Dr. Sungmoon Jung of Florida State University and Dr. Forrest Masters of the University of Florida Engineering School for Sustainable Infrastructure & Environment on their study on screen enclosures. After some deliberation the TAC voted unanimously that an addendum to the report which addresses the following issues be issued:

 

a). What are the implications of material property performance.

 

b). Clarification on wind speed conversions and what does it mean in the context of wind load requirements.

 

c). Provide more specificity on the type of failure which occurred during testing

 

The TAC also discussed and unanimously approved a continuation of this research project to address the following issues:

 

a). Characterization of Mechanical resistance of (semi-rigid) connection details.

 

b). Further research involving full scale testing at IBHS to cover snap-lock systems and hip roof type connections.

 

c). Characterization of pressure loading in boundary layer wind tunnel.

 

Investigation of wood structural panels for opening protection. ( Project #3 )

 

The TAC heard a presentation of a final report from Dr. Forrest Masters of the University of Florida Engineering School for Sustainable Infrastructure & Environment regarding their findings of wood structural panel research. After some deliberation the TAC voted unanimously to forward the following suggestions for future research projects which address the following issues:

 

a). Study catenary loads and develop equations for designers and establish baseline parameters for typical panel materials, thickness, and physical properties.

 

b). Research other combinations of hardware and wall types (i.e. cmu and brick veneers) to determine if the one-approach-fits-all approach proposed in the study is acceptable or requires modifications to achieve sustainability.

 

c). Research to develop a prescriptive  design solution for large openings that require more than one panel using APA T460 as a starting point for designing multi-panel configurations

 

d). To include research on corrosion control of fasteners in aluminum and concrete substrates as an addition to the fastener corrosion research project proposed by the Roofing TAC.

 

Feasibility study for in-home storm shelters in Florida residential                                                    homes. ( Project # 5)

 

The TAC heard a presentation from Dr. David Prevatt from the University of Florida Engineering School for Sustainable Infrastructure & Environment on their Phase I study on in-home storm shelters. After some deliberation the TAC voted not to continue with further research on this topic. The following are some of the concerns raised by the TAC members:

 

a). What is the best method to reinforce the roof connection on to the existing exterior walls so that the roof does not dislodge?

 

b). Homes that were built prior to 1965 used cut rafters for roofs that utilized the interior partitions are load bearing partitions for ceiling joists and every interior partition became a sheer wall in all directions.

 

c). Structures built prior to 1965 were more rigid and robust compared to structures built more recently.

 

d). The feasibility study indicated that an in-home shelter was not feasible.

 

f). ICC 500 has already established a guide for in-home storm shelters.

 

e.) FEMA has already conducted a study on the subject.

 

The TAC listened to a presentation by Jaime Gascon of Miami-Dade County Product Control involving research topics by Florida International University. This presentation was for informational purposes and no motions by the TAC were needed. These projects were well received by the TAC members. (See attachment for the list of the projects)

 

The TAC heard a potential research project involving a feasibility study on alternatives for restrooms located in flood hazard areas presented by James Schock. After careful deliberation by the TAC, they voted 5 to 3 not to present this potential research topic to the chairpersons TAC.
