WebThe slenderness ratio (ratio of effective length to the least lateral dimension) is less than 12 in the short reinforced column. Short columns fail due to crushing or yielding of the steel bars. The loads that a short column may support depend on the dimension of cross-section and the strength of materials. Short columns show a little flexibility. WebUnbraced length ratio, Minor Value >= 0; 0 means use program determined value. Unbraced length ratio, Lateral Torsional Buckling Value >= 0; 0 means use program determined value. Effective length factor, K1 Major Value >= 0; 0 means use program determined value.
WebOct 24, 2024 · Parking structures may be of particular concern because diaphragms are not assigned to ramps, but rather, only to horizontal area objects. As a result, when interconnecting beams are not present to serve as bracing, effective column length may become very long. To design such columns, refer to the lower column segment.
