Introduction column buckles. • For lh values in between, the failure mode is not clear and depends on imperfections in the column and the way the load is applied. Therefore, BS8110 defines: • Short columns: lh≤15 for a braced column and lh≤10 for an unbraced column. These ratios must be met for both axes modated in a column face, using mechanical end-bearing connections based o n ACI 318, pg. 315-49 Table 6-Maximum spacing of column ties pe r ACI 318, Section 18.104.22.168 ,pg. 315-49 Table 7-Minimum requirements for column spiral spacers, pg. 315-49 Table 8-Bundled bars as column verticals-Design and detail data, pg. 315-5 (vii) Additional reinforcement requirements in bored piles and barrettes; (viii) Refinement of ductility detailing in beams and columns; (ix) Additional ductility detailing in walls.
