Correct. The fabricator/erector has requested the staggered scenario for all beam to column web connections for ease of erection. I wasn't concerned with the connections not part of the braced frames but was wondering if the BF staggering would introduce eccentric forces at the WP...
I'm working on a traditional structural steel braced frame connection with a WF beam bolted/bolted with clip angles to the web of a WF column. Also included is a HSS shape diagonal welded to a gusset PL that has it's horizontal edge welded to the beam's bottom flange and the plate's vertical...
Thanks to all for the prompt responses. The framing supports a mezzanine space situated above a restaurant. The mezzanine overall area is small; approximately 500 SF. The framing consists of W12x19 beams and girders supported by HSS4x4x5/16 columns. Girder/beam spans vary from 12 ft to 6 ft. The...
A steel erector has asked to review a mezzanine project that involves recently installed composite beam framing where the steel anchor studs were installed along the deck's high flute. We have 3" concrete over 1 1/2"x18 ga composite deck (4 1/2" slab) with 3/4"x4" headed studs. In this...
Assuming that a steel "L" shaped bent plate has the same dimensional properties as a rolled steel angle, are the structural strength capacities the same?
I can see the bent plate having a slightly less strength if the "k" dimension is less but I don't believe that there is a process in place...
Are long slotted holes prohibited for single plate connections if the holes are oriented normal to the design load? The AISC Steel Manual verbiage only addresses standard and short slotted holes but I can't find any LSDT holes prohibition.
Furthermore, can a ST joint be used in this situation...
I'm designing steel stairs that are using bamboo, Brazilian Cherry or ash as the treads which are 10" wide x 2'-8" length. Is there a site where the structural properties for these species can be located? Or is it a situation where these species of wood are laminated over a structural grade...
The typical bearing depth for a K-Series joist is 2 1/2". I have an alteration project where new joists will bear atop existing steel beams. I can add a new strucutral member atop the existing beams to achieve the standard 2 1/2" bearing depth. The other option is to specify a 3...
I realize that this is soemwhat of a leading question(due to fabrication requirements, geography, project requirements, etc.) but in general are the lead times for open web joists longer than the lead times for rolled W shapes?
TIA
