Based on the technology design and the structural conceptual design,the structure design,foundation design,installation,and the control of the maching precision of the tall and slender steel tower are studied.

According to the random vibration theory, the whole process while the freight cars run on the Tian Sheng bridge with steel tower high piers is simulated by the computer.

Because the wind load and the structural wind-induced response have the fluctuating property of wide frequency and varied amplitude, the fatigue damage should be considered in the design of slender steel towers always under wind a.
