Calculations for allowable design loads consider bending, shear, combined bending and shear, web crippling, and panel pull-over. The suction values do not address the strength of the fastener/purlin connection.

Fastener to Purlin Connection In some cases the uplift strength of the roof panel system may be controlled by the connection of the fastener to the purlin. Experience has shown that this is generally not the case. The panel will pull over the head of the fastener before the fastener pulls out of the purlin. To verify that the fastener/purlin connection exceeds the allowable capacity of the roof panel refer to DPL 95 for the allowable capacities of the fastener to purlin connections.

The uplift strength of the MR-24 panels can be increased by using the Seam Reinforcing Clip (560612) or by using the Clip Spacer (560746) and double clips (PRONTO detail F432). The allowable design loads are based on testing and the results are interpreted according to the 1996 AISI specification. The use of the Seam Reinforcing Clip or the Clip Spacer assembly would not have an effect on the panel strength under gravity loads. Refer to PEL 412 for a description of the Seam Reinforcing Clip.

Gable Trim Clip The Gable Trim Clip assembly consists of the Trim Clip base (630026-Insulated Purlin; 560093-Uninsulated Purlin) and Lockseam Tab (560003).

For the Gable Trim Clip assembly use an allowable uplift capacity of 300 lbs. If the design uplift load exceeds 300 lbs, install additional Gable Trim Clip assemblies on the gable angle spaced between the purlins. Installing a Seam Reinforcing Clip (560612)on the gable trim clip assembly will not increase the uplift capacity of the gable trim clip.

Fastener to Purlin Connection In some cases the uplift strength of the roof panel system may be controlled by the connection of the fastener to the purlin.

Fastener to Purlin Connection

In some cases the uplift strength of the roof panel system may be controlled by the connection of the fastener to the purlin.

Experience has shown that this is generally not the case. The panel clip will release the panel before the fastener pulls out of

the purlin. To verify that the fastener/purlin connection exceeds the allowable capacity of the roof panel refer to DPL 95 for

the allowable capacities of the fastener to purlin connections.

Increasing Uplift Capacity

One method to increase the uplift capacity is to install a self-drilling screw through the top of the seam at each panel clip, as

shown in the detail below. This prevents the seam from unlatching at the panel clip and increases the design uplift load to 70

psf for a 2'-6" span and 40 psf for a 5'-0" span. This method should be limited to small areas of the roof. This is not an FM

approved detail.

A bead of sealant should be applied to the top of the panel clip during installation. As can be seen in the detail, the screw is

installed outside of the factory-applied sealant. This, along with the sealant applied to the top of the panel clip, makes the

potential for leaking at the fastener negligible. Use a fastener painted to match the roof panel color be in order to minimize

the appearance.
