［摘要］对于支架式单管塔，根据《钢结构单管通信塔技术规程》(CECS 236∶2008)计算风荷载时，不考虑天线与筒体的相互影响，计算值比较保守。采用高频动态测力天平技术，对22种支架式单管塔节段的刚体模型进行风洞试验，并将风洞试验结果与采用《钢结构单管通信塔技术规程》(CECS 236∶2008)计算得到的理论计算值进行对比。结果表明，根据风洞试验得到的风荷载都小于理论计算值，体型系数的综合调整系数介于0-50~0-80之间。

Abstract:The interaction of antenna mounting and monopole is generally ignored when the wind load of monopole with direct antenna mounting is calculated according to Technical specification for steel communication monopole (CECS 236∶2008), so the calculation value is conservative. The high frequency force balance (HFFB) technology was used to conduct wind\|tunnel test for rigid models of 22 kinds of  monopole segments with direct antenna mounting. The wind\|tunnel test results were compared with the theoretical calculations calculated using the Technical specification for steel communication monopole (CECS 236∶2008). The results show that the wind load obtained from the wind\|tunnel test is less than the theoretical calculation value, and the comprehensive adjustment coefficient of the shape coefficient is between 0-50 and 0-80.

Keywords:monopole with direct antenna mounting; wind-tunnel test; shape coefficient
