Design of Composite Beam Column Excel Sheet
The presence of floor systems rigidly connected to the beams of unbraced steel frames has long been known to increase the stiffness of such frames. A recent investigation into the behavior of an actual unbraced steel frame with composite precast concrete floor panels did show that such was the case. It was therefore expected that the floor systems would have the same effect on the maximum strength of unbraced steel frames.
When an unbraced frame is subjected to lateral loads the columns apply end moments to the beams at the beam-to-column connections.
