302. Where did you hear about these mystery girders?
The NIST report is a grossly flawed and highly deceitful document and you won't come to any clear understanding of how the WTC was built by studying it. It's full of half-truths and missing information and that includes information on the joist girders.

Are the Scholars of Truth and all the other conspiracy sites and organizations also involved in the cover-up? You seem to be the only person on earth to claim knowledge of these 8 joist girders laid out on each of the the truss framed floors. (Never mind that four of them would be useless -- parallel to the primary long span trusses, they would have no truss legs to support!) Were all the pictures and videos of the WTC construction era doctored also? Were these girders installed by secret agents under the cover of night?

Anyway all the elevators (except for tenant modifications) were in the cores and all the core floors were beam framed, so we're only talking about the floor diaphragms to begin with, which makes the whole progressive collapse fairy tale impossible.

So you say. Horizontal beam framing contributes nothing to vertical load capacity. They distibute it. The hat truss and floor assemblied already performed that function. The core works structurally in tandem with perimeter columns. The planes damaged quite a few core columns also. When floors sagged as a result of fires they pulled the exterior walls inside. There are photographs and eyewitnesses to this. The load bearing capacity of the bowed perimeter columns was reduce and the damaged core had to take up the slack. There is only so much weigh it can bear. Both system failed in tandem.
