What Kind Of Support Does The Stability Of Bailey Beam Rely On?

In order to ensure the rigidity and stability of the planar Bailey beam outside the truss plane, reduce the calculated length of the chord outside the truss plane, and bear possible lateral loads, the Bailey beam should be supported laterally. Supports can generally be divided into horizontal supports (upper and lower chord planes, horizontal and longitudinal), vertical supports (at both ends and middle of the truss), and tie rods. Pairs of steel trusses can be arranged with horizontal horizontal supports along the lower chord and upper chord planes respectively, and vertical supports are arranged at the two ends and the middle of the steel truss with vertical rod planes at appropriate distances. There are many steel trusses in the roof structure, and the upper and lower chord horizontal supports and vertical supports can be set only at both ends and between two adjacent trusses at regular intervals. For the remaining trusses, tie rods are only set at the upper and lower chords at appropriate intervals; When there is a heavy crane or necessary, longitudinal horizontal supports can be added between the lower chord end nodes of the truss. In a four-sided or multi-sided tower, transverse partitions should be arranged at regular intervals to ensure the rigidity of the tower and the geometric invariance of the cross section.
