摘　　要：结合河北野生原度假村温泉馆工程,讨论了预应力轻型张弦梁屋盖的设计要点。利用MIDAS GEN软件对张弦梁的结构性能进行非线性分析,结果表明脉动风振、积雪或活荷载不对称、不均匀作用是该类结构失效的控制因素,而地震作用对结构内力影响不大,不均匀温度作用下结构产生较大变形。对张弦梁稳定设计要点进行探讨并给出相关设计措施。利用ABAQUS软件对拉索与上弦箱型梁连接节点进行数值模拟分析,验证了节点的可靠性。相关结论可供类似工程设计参考。The paper discussed the design main points of the beam string structure for the light roof,based on the project of the Hebei Ye-Sheng-Yuan Resort spring museum roof.The structural performance of beam string structure was analyzed by MIDAS GEN software,and the results showed that the high-frequency dynamic wind load,the asymmetry and uneven snow or live load are the control factors of this kind structural failure,the seismic effect has little effect on the structure internal force,and the structure produced large deformation under the uneven temperature action.The stability design key points of beam string structure are discussed and design measures are given.The numerical simulation analysis of the connection nodes between lasso and box beam was carried out by ABAQUS software,and verified the reliability of the node.The relevant conclusions can be used for similar engineering design.
