Analysis on Mechanical Behavior of Relay Vertical Rotation for Steel Arch Tower

Table 1

Comparison between proposed method and traditional method.

Rotating member	Proposed method	Traditional method	Improvement
Tower			(1) Mass of temporary structure is reduced; (2) Amount of work high above the ground is reduced
Chief strut			(1) Tension force is significantly reduced
			(1) Mass of support structure is reduced; (2) Amount of work high above the ground is reduced

Note: The blue member is temporary structure used in rotating tower, and the red member is temporary structure used in rotating chief strut.
