轻型电视天线塔桅结构的探讨

Study of Mast Structure of Light-Duty Antenna Tower for Television

本文讨论安装开路和闭路电视系统所用发射与接收天线的支承物——轻型电视天线塔桅结构的外型设计,及其截面选择的理论计算方法,并用有限元法计算塔身在风载作用下杆件内力及结点位移的方法.

This paper discusses the design of the external form of mast structure for the light-duty television antenna tower,used as the supporters of the transmitting and receiving antennas in the open-and closed-circuit television system,and the computa- tional method for the choice of cross section is given.The inner forces of rods in the tower body under the influence of wind loads and the displacements of junction points are calcula- ted by the finite element methods.
