[#43] Pick up the correct statement applicable to cased columns.

(A) Single I-beam or channels back with or without flange plates may be used

(B) The overall dimensions of the steel section do not exceed 750 × 450 mm over plate if used

(C) The column is unpainted and is solidly encased in ordinary dense concrete with 10 mm aggregates having a minimum of cube strength 160 kg/cm 2 at 28 days

(D) The surface and edges of the steel column should be provided a concrete cover not less than 50 mm

Correct Answer

Single I-beam or channels back with or without flange plates may be used
