The preferred option for a specific application will depend on the ratio of wind load to gravity load, and on manufacturing and erection efficiency. When wind load is less than 0.75 times gravity load, it will normally be more economical to use the through-fastened option. The higher gravity will control the design of the supporting member so reducing uplift capacity will not increase section size. The 1996 edition of the AISI specification added through-fastened provisions for axial load. This provided a rational method for determining axial capacities for sections with through-fastened panel attached to one flange.
Issues are similar to through-fastened for bending discussed above.
This condition occurs at purlins in line with an endwall column location. Unfortunately, this is causing the specifications to become more complex. Design aids including computer programs and design manuals are critical to remaining competitive. Loseke Technologies is dedicated to providing the best possible programs to the metal building and metal component industries. PanelPlus determines panel diaphragm strength as well as panel properties and capacities.
