Unformatted text preview: c '=4 ksi, f y =f yt =60ksi. b) Design a circular spiral column having symmetrical reinforcement to carry the same service loads and moments P= 100 k DL + 80 k LL and M=50 kft DL + 90 kft LL. At the critical section for shear V= 10 k DL +30 k LL. Use the provided strength interaction diagrams from pages 1075 and 1076 of the text by Wight and MacGregor (copy included with this workshop) to obtain a design. Assume 3.0 inches from the center of longitudinal bars to surface of member as shown. Select crosssection diameter in full inch increments. Select the steel ratio to gross cross section g in the range of 0.025 to 0.045 for your final design. Determine also the maximum spiral pitch (spacing of adjacent loops) for #3 spiral reinforcement. f c '=4 ksi, f y =f yt =60ksi. A Family of Design Interaction Diagrams from Wight and MacGregor: f c =4ksi, f y =60 ksi 11122009...
