1. A square reinforced concrete column has a dimension of 400mm x 400mm. There are eight (8) rebars with diameter of 25mm placed symmetrically on two-sides. The distance of the compression bars from the compression side (d') is equal to 70mm. The material properties of the column are: fc = 30 MPa and fy = 414 MPa. 400 a. Determine the values of P. if the column is subjected to pure axial compression load only. This will be the coordinate of P. in the interaction diagram b. Determine the values of P, and Mn if the column is subjected to balanced condition. This will serve as the coordinates of the balance point (P. and Mo) in the interaction diagram. C. Determine the value of M. if the column is subjected to pure bending only This will be the coordinate of the M. in the interaction diagram. d. Determine the values of Pn if the column is subjected to tensile load only This will serve as the coordinate of T, in the interaction diagram. e. Compute the values of P. and Ms assuming the different values of "c" (location of neutral axis) c=161.17 mm (coordinates of Pn and Mo) C = 123.76 mm (coordinates of Pea and Mna) C = 386,35 mm (coordinates of P3 and Ma) c = 290.81 mm (coordinates of Prand Mna) Plot the interaction diagram based on the computed values of P. and Mo.
