摘　　要：大开口鼓蜂窝四撑杆索穹顶结构是一种新型结构形式,针对这一特定的结构体系,基于二次奇异值分解法,结合MATLAB计算程序得出结构整体可行预应力,建立ANSYS有限元模型进行验证并分析该结构在恒载、活载、风载及温度荷载作用下的内力及位移关键响应.进一步研究厚跨比、预应力倍数及矢跨比等参数对结构静力性能的影响.分析表明,大开口鼓蜂窝四撑杆索穹顶结构具有良好的静力性能,整体刚度大.给出结构厚跨比、预应力及矢跨比的合适取值范围,为大开口鼓蜂窝四撑杆索穹顶的工程应用提供了参考依据.The large-opening drum-honeycomb-type quad-strut cable dome structure is a new type of structure.For this particular structure system,the feasible prestress of the whole structure is obtained based on the quadratic singular value decomposition method using MATLAB program.ANSYS finite element model is established to verify and analyze the structural internal force and displacement under dead load,live load,wind load and temperature load.The influence of the thickness-to-span ratio,prestress ratio and rise-to-span ratio on the static performance of the structure is further studied.The results show that the structure has good static performance and high stiffness.The suitable scopes of the thickness-to-span ratio,prestress and rise-to-span ratio are given,which provides a reference for the engineering application of the large-opening drum-honeycomb-type quad-strut cable dome.
