PDF CHAPTER 4. ANALYSIS AND DESIGN OF COLUMNS - WordPress.com a) Tied Columns: Columns where main (longitudinal) reinforcements are held in position by separate ties spaced at equal intervals along the length. Tied columns may be, square, rectangular, L-shaped, circular or any other required shape. And over 95% of all columns in buildings in non-seismic regions are tied columns. P-m Characteristics of Reinforced Concrete Sections P-M interaction is located at the point of maximum moment. To evaluate these assertions, two parametric studies were performed. In the first study, square column cross-sections were analyzed while the second study considered rectangular wall cross-sections. Concrete compressive strength and reinforcement ratios were considered as variables. ACI Column Interaction Diagram Spreadsheet - Civil ...
