As per IS:800 – 1984 Clause 5.7.2.3
The slenderness ratio of the lacing bar for the compression members shall not exceed 145.
Note:
- In riveted connection, the effective length of the lacing bars for the determination of the permissible stress shall be taken as the length between the inner end rivet of the bar for single lacing, and as 0.7 of this length for double lacing effectively riveted at the intersection.
- In welded connection, the effective length shall be considered as 0.7 times the distance between the inner ends of the weld connecting the lacing bars to the member.
