摘要
本文利用自行编制的非线性有限元程序,对单层鞍形网壳结构在不同网格布置、不同高跨比以及不同边粱截面等情况下的荷载—位移全过程做了大量计算,进而对这类结构的稳定性能及其用于实际工程的前景作了较深入的探讨.
In this paper, the complete curves of load—deflection response of single—layer saddle—back reticulate shells of this type with different network' forms, different rise—to—span ratios and different cross—sectional rigidities of the boundary beams are calculated by a nonlinear finite element computer program compiled by the authors, and the stability characteristics of the structure, as well as the prospect of application of single-layer systems in practice are revealed.
