Beam To Beam Moment Connection ??
Beam To Beam Moment Connection ??
(OP)
I have a 1.5m overhang with concrete and decking sheet. Main beams and secondary are on same level so moment connection needs to made between the main and secondary beam (Cantilever Structure.jpg). I have two options for connection.
1. Fin plate in between and flat plate on top and bottom (Con type-1.jpg)
2. End plates on both sides (Con type-2.jpg)
Is the behavior of type 2 connection same as type 1 ??
I am using IDEASTATICA for analysis of connection and both are working.

Another thought on cost saving measures - depending on the loads and your girder capacity, you might be able to get away with a backup moment connection on every 2nd beam instead of every beam. If you only have a few of these, probably not worth it, but if you have dozens of them it might make sense to look into it.

I agree....but I suggested the second option because I thought "option 01" would created a problem as far as top of steel (TOS) elevation goes. Not sure if the concrete guys could address this while forming.....but i've never had deck sitting on something like that before. (I.e. the bolt heads.)

You pay quite a premium for that, in particular, if they are field welded. Your seal, your call...

I am also intrested in option 1 but only issue in this connection is top bolt head, these bolts head will creat problem at site for fixing the floor decking sheet.
Any one can suggest how i can fix decking if i choose option 1??
Floor Decking is 65mm thick and sheet rib height is 22mm.

What is the design moment? You might be able to use a reasonable size flush end plate - beam has an end plate and a short section of beam is welded to the main beam with an end plate.
If the overhang is only 1.5m, you should be able to shop weld those to the main beam.
