摘　　要：在参数化设计快速建模的基础上,采用ANSYS软件分析了杂交型"凯威特-联方"马鞍型网壳在不同结构参数下的静力和动力性能.运用时程分析法对"凯威特-联方"马鞍型网壳进行地震响应分析,通过分析杆件和节点最大内力及位移时程响应曲线,得到结构内力与位移的分布规律.结果表明:在矢高f、环向区域份数Kn和径向节点圈数Nx一定的情况下,上部结构径向圈数Ns与Nx的比值Ns/Nx接近0.8时网壳结构的整体挠度最小;跨度S与结构整体挠度和最大水平支座反力均成正比;在地震作用下网壳结构没有出现强度破坏,这为网壳结构选型优化和实际工程抗震设计提供了理论依据.Kiewitt-Lamella saddle reticulated shell is a common form of hybrid shell.Based on the parametric design modeling,the static and dynamic performances were analyzed under different structural parameters by using ANSYS software.Time-history analyses under seismic actions were performed in this paper.The distribution laws of maximum dynamic internal forces and displacements were obtained and studied by analyzing time-history response curves.The results show that,on condition that the rise height f,ring to symmetric regional copies number Kn,and radial node ring number Nx are definite,the minimal overall deflection is tested when the ratio between culminating point connection radial laps Ns and Nx is close to 0.8.Span S was proportional to the whole structural deflection and maximum horizontal reaction force.Saddle reticulated shell did not manifest strength collapse under seismic action,which provides theoretical basis for both lectotype optimization and practical seismic design for this kind of reticulated shell.
