P’ = gravity loads acting along v-v axis, including EX-facta™ Purlin Design Software Example 31 Introduction Stramit Exacta® C&Z Purlinscome in sizes of 150, 200, 250, 300 and 350 are subtly but importantly different to standard Stramit® Z&C Purlins. Yield strength: fy = 350 MPa. Stramit offers a wide range of standard C and Z purlins from 100 to 350 deep in several thicknesses. offers 8-, 9. 732 4 Cold Bend DESIGN of PURLINS, SAG RODS, and TIE RODS (updated) Design of Purlins, Sag Rods, and Tie Rods using Dead and Live Load Combination . For 2x6s purlins, the posts are spaced at 6 feet distance. Capacity values have been calculated in accordance with the AISI 2001 design manual. Bracings 2.
