splice location for steel beam

splice location for steel beam

splice location for steel beam

(OP)
is it better to do case 2?
i'm confused between structural strength and constructability in this case.

i place steel column splice on same elevation though.

RE: splice location for steel beam

Assuming it is a truss, I would go with Option 1. Make sure you show a splice in the web member as well.

It's no trick to get the answers when you have all the data. The trick is to get the answers when you only have half the data and half that is wrong and you don't know which half - LORD KELVIN

RE: splice location for steel beam

If something you may get some final hanging strength from option 2 for some lesser constructibility ... With proper construction the structure should always be far from such kind of events requiring such hanging reliabilty ... furthermore in inspections more likely to forget one joint in option 2 than in 1. So if we are limited to 1 or 2 I would choose 1 and ensure proper joints are in place.

RE: splice location for steel beam

I would choose option 1 as well for constructability issues.  However, I would probably modify the web configuration to a Warren truss to allow for an easier splice of the web members.

RE: splice location for steel beam

If the splices are for transport, then I would not splice the web member, just leave it out during transport and bolt it in place in the field.

If the mecessity for the splices is only due to the maximum available length of the rolled sections, there is no need to splice the web member, only the top and bottom chords.

Option 1 for me too.

Without knowing why!

If you can assemble the truss for shipping, then #1. Consider assembling the whole truss, including splices, in the shop and shipping as one piece. It saves labor cost, it may increase freight cost.
