Question: A short rectangular reinforced concrete column shown in the figure is to be a part of a longspan rigid frame and will be subjected to

A short rectangular reinforced concrete column shown in the figure is to be a part of a longspan rigid frame and will be subjected to high bending moments combined with relatively low axial loads causing bending about the strong axis Because of the high eccentricity steel is placed unsymmetrically as shown with three No 14 No 43 bars near the tension face and two No 11 No36 bars near the compression face Material strengths are fc 6 ksi and fy 75 ksi Construct the complete strength interaction diagram plotting Pn vs Mn relating eccentricities to the plast
