| Abstract: | 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. |
