WTC Core Details[W:183]

Re: WTC Core Details

You can see the pipe detail here, in case you missed it..

And here on the drawing

33-1 LQ.jpg

Which accomodates the 5th truss in from each long span side (5th truss, 4th double) bridging straight along to the truss on the short span core perimeter.

The core side of the floor truss were supported on the angles welded and perhaps bolted to a belt girder which was cantilevered away from the core so that while the core perimeter columns reduced in cross section and were aligned axially beam stubs were longer at you ascend the core. The top chord of the double trusses were bolted to the seat angles...

The truss connections at the core were not the same for long and short span trusses. They were both connected at the top chord to a welded channel attached to the perimeter cores by the fixings shown in the drawings. The bottom chord of the long span trusses was typically bolted. The bottom chord of the short spans were not.

ADD I posted the seat connections, the N/S core side truss seat connections are type 23 mainly, with 4 each of 22,21 and 20.
The E/W connections were all 17s with 4 x 15s, and 2 of the pipe and plate detail as shown in drawing AB - 6 - 33.1

the cores were oriented 90 degrees to one another.

There were studies with photos of the failed truss connections... Real world works for me... look it up.

I have no idea what you are writing about and why it would be relevant.

I didn't expect you comprehend it. Let alone catch onto why it is relevant.
If we know where the truss chords are at for the long and short spans at the core end, then we know how accurate "contemporary steel design" is in terms of the bottom chords in particular for those trusses.

The point is. It is accurate. Which Gamolon for some reason disputes.

That has nothing to do with anything whatsoever. The fact that the cores were at 90 to each other was to stop the buildings acting in concert.

What does that have to do with this discussion ? The structural drawings that I am referring to start "AB" meaning that they apply to BOTH towers.

You'll never see the actual construction drawings of the long or short span trusses. He'll keep trying to divert attention by posting other drawings and try to make them look relevant to the discussion. I wonder why he's so against posting the actual construction drawings of the long and short span trusses?

I'm with you SanderO. I have no idea how drawing 6-AB1-33.1 correlates to the accuracy of the 1964 booklet drawings of the long and short span trusses. Why gerrycan refuses to supply the engineering stamped construction drawings of the long and short span trusses is beyond me.

What you clearly have not yet realised is just how wrong you were about the truss arangements as shown in "contemporary steel design".

You misread the drawing in that booklet. The drawing 33.1 is in this thread, which shows the long span run bridge onto the outside of the core perimeter being accomodated by the short span transfer truss being set further from the columns by way of the 5" pipe detail.

Show me where "contemporary steel design" is wrong.It shows EXACTLY the same truss arrangement at the long and short span ends as can be seen in photographs and inspection videos.

What you have failed to comprehend is that the element shown in red below is the perimeter truss bridging the short span transfer trusses, leaving the top and bottom chords the correct distance from the core and for the bottom chord to be bolted, unlike the short span trusses, where there is no connection to the bottom chord.

God help me! I just can't stay away from your trainwreck!

:lamo

Are you telling me that you think the element you marked in red below...
red SP truss.jpg

...is part of the bridging truss and independent of the long span truss shown? That the bridging truss ran along the columns and was perpendicular to the long span truss shown?

That is a real stretch, SanderO, or an outright lie. You have denied so many real world realities as Bush, Cheney et al lied.

The same goes for all the USGOCT conspiracy theorists.

GWB and DC lied... both wanted and excuse to invade Iraq. Gov, corps and media lie all the time because they have agendas. They are rarely transparent.

You have to read between the lines.

I think 9/11 was blow back for decades of US ME policies. Don't expect the US gov to fess up to that. Yea we acted like asshats and got what we deserved.
