摘要
从几何稳定性、传力路线、受力敏感度等多角度,对空间桁架等屋盖结构体系的受力性能进行分析,为结构选型、建模、具体设计及审图工作提供了理论上的参考。
The stress performance of the space truss as a roof structural system is studied from geometric stability, load transfer paths, stress sensitivity, in order to give theoretic references for structure model selecting, modelling, detailed design or check of drawings.
