摘　　要：张弦粱结构承受的风吸力大于结构自重等竖直向下的荷载时,预应力索将松弛退出工作。运用SAP2000对某张弦梁结构在预应力索失效后的承载力、变形和整体稳定性进行了分析。计算结果表明:下弦索失效后,荷载只能由主弦杆承担,导致某些构件承载力不足,添加抗风锚杆后各构件的承载力均能满足;稳定拉索和交叉稳定拉杆的设置提高了结构的整体侧向刚度,且有效地抑制了侧向变形。When the wind suction exceeds the vertical downward load,the prestressed cable will be inactive. Inthis paper, the bearing capacity, deformation and the overall stability of a beam string structure were analyzed bySAP2000. The calculation results show that： when the prestressed cable fails, the load can be borne by the mainchord member, leading to some lack of capacity. After adding the wind bolt, the bearing capacity of each compo-nent can be met; the set of stable cable and stable cross rods can not only improves the overall lateral stiffness ofthe structure and effectively inhibits the lateral deformation.
