41. Lacing bars in a steel column should be designed to resist A. Bending moment due to 2.5% of the column load B. Shear force due to 2.5% of the column load C. 2.5% of the column load D. Both (A) and (B)

Bending moment due to 2.5% of the column load
Shear force due to 2.5% of the column load
2.5% of the column load
Both (A) and (B)

Detailed SolutionLacing bars in a steel column should be designed to resist A. Bending moment due to 2.5% of the column load B. Shear force due to 2.5% of the column load C. 2.5% of the column load D. Both (A) and (B)

43. Angle of inclination of the lacing bar with the longitudinal axis of the column should preferably be between A. 10° to 30° B. 30° to 40° C. 40° to 70° D. 90°

10° to 30°
30° to 40°
40° to 70°
