中文摘要：
建立了双支撑杆的主材或斜材横向位移稍大时的失稳模式，寻找出双支撑杆的两种失稳模式与结构尺寸、主材或斜材横向位移的关系，给出两种失稳模式间的转换临界值，该值的准确性得到了试验的验证。研究成果对于指导双支撑杆的尺寸设计、提高输电铁塔主材或斜材的抗失稳能力均具有应用价值。
英文摘要：
The buckling modes were established for legs or diagonal bracings of the double-supporting bracing under the large transverse deformation. The two buckling modes of the double-supporting bracing were studied as well as its relationship with structure sizes and transverse deformations of legs or diagonal bracings. The transition threshold values between the two buckling modes were presented and the values were checked by buckling experiments. The results have practical signifieances in the guidance of the double-supporting bracing size design and developing the anti-buckling capacity of legs or diagonal bracings in transmission towers.
