摘要

采用子空间迭代法计算单层鞍型网壳的自振特性,利用圆管截面空间梁系弹塑性本构关系,用时程分析法计算单层鞍型网壳的弹塑性地震响应,通过对SDAP和ANSYS有限元程序计算结果比较分析,总结出单层鞍型网壳的自振特性、地震内力响应及地震内力系数随参数的变化规律。
The sub-space iteration is used to calculate the free vibrational characteristics of the single-layer saddle-curve reticulated shells. Base on the elastic-plastic constitutive model of the three-dimension beam element with pipe section, the step-by-step integration procedure is used to analyze elastic-plastic seismic response of the single-layer saddle-shape reticulated shells. By analyzing results of the program SDAP and the FEM software of ANSYS, the rules of the free vibrational characteristics, the seismic inner-force response and the seismic inner-force coefficient of the single-layer saddle-shape reticulated shells are summarized.
