1. Design Moment for bending about y-axis, kN-m. 2. Eccentricity (using the design moment) of the load along the y-axis, mm 3. Eccentricity (using the design moment) of the load along the x-axis, mm
The column is subjected to the
following service loads:
Axial Dead Load = 400 KN
Axial Live Load=650 kN
Moment about the X-axis due to
Dead Load on the top of the
column = 151 kN-m
Moment about the Y-axis due to
Dead Load on the top of the
column = 138 kN-m
Moment about the X-axis due to
Live Load on the top of the column
= 165 kN-m
Moment about the Y-axis due to
Live Load on the top of the column
= 140 kN-m
Moment about the X-axis due to
Dead Load on the bottom of the
column = 140 kN-m
Moment about the Y-axis due to
Dead Load on the bottom of the
column 131 kN-m
=
Moment about the X-axis due to
Live Load on the bottom of the
column 162 kN-m
Moment about the Y-axis due to
Live Load on the bottom of the
column= 144kN-m
If the end moments results to the
column having a singular curve for
both axes, and the column is not
subjected to any transverse loads,
determine the following:

A concrete rectangular column
with dimensions A= 420mm and
B= 580 mm (See figure below) is
braced against side sway. The
column is to be fixed on both ends
for bending about the Y-axis and to
be pinned on both ends for
bending about the X-axis. The
unsupported length is 7.7 meters.
Use f'c-35 MPa. Reinforcements
are along "B" only.
