Question

The loor system shown below is subjected to a uniform load of q 120 psf. All connections are shear connections, I- 10 ft o.c. 30 ft Gl C1 10 ft О.С. 30 ft Floor Span I- 30 ft 30 ft Draw the free body diagram of girder Gl showing the loads applied by the beams it supports and the reaction forces that are transmitted to the supporting columns C1 and C2. You do not need to analyze all beam, girder, and column members like the in-class erample, just girder G1.
