The invention discloses a single-layer chord-supported reticulated shell structure and an anti-seismic property testing method. The single-layer chord-supported reticulated shell structure comprises a single-layer reticulated shell main body, a first-stage radial inhaul cable, a side truss and an inner truss, the side truss is arranged on the lower portion of the single-layer reticulated shell main body, a main supporting rod and an auxiliary supporting rod are fixedly connected to the upper portion of the side truss, a first-stage radial inhaul cable is arranged in the single-layer reticulated shell body, a first-stage annular inhaul cable is arranged on the upper portion of the first-stage radial inhaul cable, the inner truss is arranged on the top of the single-layer reticulated shell body, a second-stage radial inhaul cable is arranged in the inner truss, a second-stage annular inhaul cable is arranged on the upper portion of the second-stage radial inhaul cable, and the upper parts of the side truss and the inner truss are connected with main ridge inhaul cables. According to the single-layer chord-supported reticulated shell, the horizontal counter force between the side truss and the main ridge inhaul cables can be greatly reduced through the side truss, the acting force of the upper portions of the side truss tends to be uniform, the effect on the vertical counter force of a support is small, the overall rigidity of the single-layer reticulated shell body can be improved, and the structural internal force is reduced.
本发明公开了一种单层弦支网壳结构及抗震性能测试方法，包括单层网壳主体、一级径向拉索、边桁架和内桁架，所述单层网壳主体的下部设有边桁架，所述边桁架的上部固定连接有主支撑杆和辅助支撑杆，所述单层网壳主体的内部设有一级径向拉索，且一级径向拉索的上部设有一级环向拉索，所述单层网壳主体的顶部设有内桁架，所述内桁架的内部设有二级径向拉索，且二级径向拉索的上部设有二级环向拉索，所述边桁架和内桁架的上部连接有主脊拉索，本发明利用边桁架可以大幅度降低与主脊主脊拉索之间的水平反力，并使边桁架的上部的作用力趋于均匀，对支座竖向反力的作用比较小，可以增大单层网壳主体整体的刚度，降低了结构内力。
