Question

What is lacing 4 battens?​

Answer 1

Answer:

The compression member comprising two main components laced and tied should, where practicable, have a radius of gyration about the axis perpendicular to the plane of lacing not less than the radius of gyration at right angles to that axis.

Answer 2

LACING:

There are two types of lacing system:

1. Single lacing system
2. Double lacing system

The lacing system should not be varied throughout the length of the strut as far as practicable.

• The single-laced systems on opposite sides of the main components should preferably be in the same direction so that one system is the shadow of the other.
• Cross (except tie plates) should not be provided along the length of the column with lacing system, unless all forces resulting from deformation of column members are calculated and provided for in the lacing and its fastening.

BATTENS:

• Compression member can also be built up intermediate horizontal connecting plates or angle connecting two or four elements of column .these horizontal connecting plates are called battens.
• The number of battens shall be such that the member is divided into not less than three bays within its actual length
