Bent rusted I-Beam W10x26 run across the top of the family room ,span 25 ft support roof truss 1

[AMM57]

I am reviewing an existing built house, and I mean into this issue:
a Colored rusted Wx10x26 I-Beam, Span 25 ft and supported a roof truss from both side and the tributary Areas approximately 25x26, and the beam supported by 6x6 wood column, the hight of those columns approximately 20 ft

first, what are the DL and LL that can be assumed in this case
can we leave the beam in place and add additional support
can I add a TJI joist to support the trusses along the 26 ft span and leave the steel beam in its place

Sounds like you need to hire a structural engineer.
