Abstract

According to the actual internal force and internal force calculation by engineering space ideal hinged truss model for different problems of UHV tower design,1000 kV in UHV Engineering double circuit lines on the same tower SZ304 as an example, by using SAP2000 finite element program, set up truss element, beam-bar element and the beam element of three different mechanics model according to the angle steel and steel pipe two component types. Research shows that: the principal axis force and the natural vibration period of the three models are similar to each other. The beam element and the beam-bar element model of principal end bending moment calculation results are similar. The lower part of the tower body and steel tube tower variable slope at principal moment of secondary stress is greater than 20%, the design should be considered. The steel tube tower, under the same conditions, the increase of material length diameter ratio, can significantly reduce the secondary stress influence.
