A built-up laced column of overall square cross-section, 300 mm size has been formed by placing four angles of ISA 50 x 50 x 6 mm at the corners of the square. If the effective height of column is 10 m, then calculate the load carrying capacity of the column. Also, check the lacing system for safety against: (i) Local buckling of column angles. (ii) Strength of lacing bars in tension and compression against shear load. (iii) Strength of M20 bolts of grade 4.6, check safety of bolt.

Transcribed Image Text:Q.7 (a) A built-up laced column of overall square cross-section, 300 mm size has been formed
by placing four angles of ISA 50 x 50 x 6 mm at the corners of the square. If the effective
height of column is 10 m, then calculate the load carrying capacity of the column. Also,
check the lacing system for safety against:
(i) Local buckling of column angles.
(ii) Strength of lacing bars in tension and compression against shear load.
(iii) Strength of M20 bolts of grade 4.6, check safety of bolt.
