| 摘 要： | 国内外张弦梁的兴建方兴未艾,而该结构的极限跨度论述鲜有报道。就此问题从结构设计因素出发,根据张弦梁的受力特点及拉索和上弦拱梁的材料极限强度条件,推导了平面张弦梁结构的极限跨度公式,并对平面张弦梁极限跨度的影响因素进行了分析。

| Abstract: | In China, the construction of the Beam String Structure is still growing, but the ultimate span length of this kind is seldom discussed. Starting from structural design factors, according to the mechanical characteristics of Beam String Structure, stay cable and the beam material limit strength condition, the ultimate span length formula for planar Beam String Structure is deduced, structure and influence factors of planar Beam String Structure ultimate span length are analyzed. |

| Keywords: | Beam String Structure ultimate span length stay cable ultimate strength |
