Chapter 8, Problem 20RQ

A5.1- An unbraced column shown in Figure 1, column A-B with square cross-section is given. The column is subjected to Dead load (unfactored): PDL = 3000 kN, MDL-top = 85 kN.m, MDL-bo = -DL-bottom = 100 kN.m. = Assume the cross-section of column is constant from top to bottom, and all the beams have width = 300 mm and height 350 mm. Using f'c = 25 MPa, fy = 400 MPa, design the column and determine the ties spacing and arrangement. Use 25M or 30M bars for longitudinal reinforcement, and 10M bars for ties. Assume clear cover to be 40mm. The design p has to be between 0.01 and 0.02. Column maximum dimension can be 500mm. т 4.0m 7.0m 5.5m + 6.5m Figure 1 B
