| 摘 要： | 为模拟对输电铁塔单角钢主材（原主材）附加一个规格相同（或略小）主材（副主材）组成十字组合截面构件对塔身主材进行加固补强工程实际，通过考虑节间斜材支撑的双角钢十字组合截面偏心受压构件承载力试验，研究了该类构件的承载力以及副主材尺寸、填板设置、螺栓个数等因素对承载力的影响，探讨了其组合截面承载力计算方法，为建立该类加固设计方法提供了依据。

| Abstract: | To simulate t he reinforcing of transmission tower, a series of eccentric compression members with combined angle iron cross-section are tested. And the effects on these members＇ bearing capacity by braces are considered. The test results show the effects on the beating capacity which caused by the dimensions of the accessional angle iron attached to the original angle iron, the form of padding plates and the number of bolt. The calculation method of these members＇ capacity is studied. It is applicable to the reinforcing design of transmission tower. |
