Webseismically confined columns The compression-controlled phi factor for columns is 0.65. Spiral reinforced columns are given a higher factor of 0.75 due to improved confinement. The tied columns factor of 0.65 was based on #3 or #4 ties at roughly 16” o.c. wrapping every other leg. A seismically tied and confined column today has #5 ties at 4 WebMar 22, 2024 · In calculating the anchorage length a maximum 12φ tail length can be considered. The anchorage length is estimated based on the rebar diameter, concrete class, steel grade and steel over strength. Minimal values for development length, l dh, are 15 cm or 8d bl, d bl being the diameter of the anchored bar. Development length, l dh, is …
