Question
Calcualte the following:
Total factored floor load in 2 decimal places, ___ kPa
Total factored uniform load on girder GH in 2 decimal places, ___ kN/m
Maximum ultimate bending moment at discontinuous end of girder JK to the nearest whole number = ___ kN·m
Transcribed Image Text:A monolithic floor framing plan is shown in the figure. The columns are
300 mm square, girders are 250 mm wide by 450 mm deep and slabs are 100 mm
thick. The floor loads include floor finish of 0.77 kPa, ceiling system of
0.25 kPa, partition load of 1.0 kPa and live load of 4.8 kPa. Bar centroid
from the edge of the beam is 70 mm.
