Suspension structures

BUILT-UP MEMBERS

Built-up members are used in many structures, such as compression members of trusses or supporting columns. They are composed from two rolled U-sections or four rolled angles. The distance between them is fixed by lacing or battening. The built-up members are economic, since the connection between the chords can be realized with elements of less volume than with continuous plates. In the design of built-up compression members the effect of shear deformation of connecting elements should be taken into account, since a shear force is acting from the compressive force during the overall buckling of the member with an initial eccentricity.
