摘要：

介绍JEC总计法和Simon总计法，制作某工程常用角钢输电塔的节段模型，在14%湍流度的均匀湍流场中进行测压风洞试验，获得迎风面和背风面主材、斜材及辅材杆件的风压系数.结果表明：与试验结果相比，JEC总计法中的长细比修正系数取值偏小约15%，背风面杆件风荷载折减系数取值总体偏大约4%；Simon总计法中的背风面杆件风荷载折减系数与试验吻合较好，但迎风面杆件体型系数较试验结果偏小约10%.基于风洞试验结果优化JEC总计法中参数的取值，提出改进总计法，由此计算得到的体型系数与试验结果以及美国规范均吻合良好.
Abstract:

JEC assembly method and Simon assembly method were introduced; transmission tower section model... wind tunnel measuring pressure test at turbulence intensity of 14% was conducted; the pressure coefficient at both upstream and downstream of the main members, oblique members and auxiliary members were obtained. Results show that, when applying JEC assembly method, the reduction factor of slenderness ratio is about 15% smaller than experimental result, and the wind load reduction coefficient of leeward members are about 4% larger.While applying Simon assembly method, the wind load reduction coefficient of leeward members agree well with the test, but the shape coefficients of the members at upstream are about 10% smaller than the experimental results. Based on wind tunnel test results, a modified assembly method was proposed by improving the accuracy of parameters recommend by JEC. The shape coefficient calculated by modified assembly method is in good agreement with the experiment result and the American standard.
