The metal deck is simple; use #12 TEK self tapping screws. Most metal deck catalogs have details and design values for this. The open web joists can be bolted down using 1/2 inch or 3/4 inch diameter bolts (one each side) depending on joist size assuming you are attaching to a wide flange beam. Look at the detail carefully and make sure all minimum edge distances are satisfied. You will also need to verify the capacity if you are using the joists for drag struts or collectors.

I'm currently working in a building expansion in an industrial plant. Due to safety reasons, field welds must be avoided as possible. The design includes roof joists and metal deck. Does anybody know if the joists can be attached to the supporting beams with bolts instead of field welds? I have never seen that before. Regards,
