摘要
利用空间梁单元有限元理论,采用电子计算机,重点对凯威特型单层球面网壳进行了详细的静力和动力性能研究。静力性能包括不同跨度,不同矢跨比的网壳在各种荷载组合下的内力与变形特点;动力性能包括上述结构的自振特性与结构在水平和竖向地震作用下的反应。在上述分析的基础上,本文对凯威特型单层球面网壳的选型和具体设计提出了重要的参考意见。
Based on the finite element theory of spacial-beam, inte nsive studies on the static and dynamic properties of Kiewitt single layer latti ced spherical shell (SLSS) have been made in this paper,in which computer app lying is necessary. The internal forces and structural deformations of SLSS with various spans and different rise-span ratios under various possible loading com binations ,are classified in static properties ,while the above mentioned struct ural self-vibration properties and structural responses to horizontal and vertic al seismic actions are included in dynamic properties. Based on the analyses ,s everal important advices on configuration selecting and practising design of Kie witt SLSS are presented for reference.
