Hi,
I was checking how the program calculated the maximum deflection, so I made a 10' by 10' simple test case using composite deck .

The Concrete Composite Deck is assigned as follow

The Deflection of the beam I was checking is the upper edge beam as shown

The distributed load applied on the beam is DL=0.156 klf and LL= 0.05 klf, which is the same as what I hand calculated.

However, using the composite effective moment of Inertia = 109.34in^4, w=0.206 klf and delta = 5wL^4 / (384EI) for simply support beam, I got 0.015 in for deflection.
versus 0.038in maximum deflection that the program is showing

It will be helpful if anyone can answer with what load combination the program is using to calculate the maximum deflection
and why the program is giving me a larger expected deflection.
Sorry for the long message!
