Dear All,
I have a condition on one of my projects that the connection engineer wants all bolts in braces to be 1" dia A325SC bolts. I have detailed the braces with oversized holes in gusset plates with 1" dia A325SC bolts. After reviewing the drawings, the engineer asked me whether the holes...
There is a mutli storied steel building with 4 sides vertical braces. V bracings and chevron bracings. All the single angle braces sizes are L6*6*3/8 and all double angle braces are L6*6*5/16. What may be the reason the design engineer has choosen different sizes for braces than choosing the...
I have a condition in my design drawing, beams having axial loads indicated. My fabricator preferred connection is bolted-bolted clip angle for beams. Web side shop bolted with STD holes and OSL field bolted with short-slotted holes. Anyone help me whether this connection will work with axial...
Some fabricators prefers to add pilot holes for ease of job, some prefers to leave without any holes.
But my point is, self drilling/tapping screws can only used for fastening thinner materials (such as sheet metals) or it can be used for thicker materials as well? (Say 1/4" thicker or above?)
I have a condition in one of my steel project, where the 1/4" thick steel deck edge bent plate has to connect with cold formed truss member by means of #12 screws. Whether these #12 screws can be driven in field (self-tapping) through 1/4" thick steel material without any predrilled holes on it?
