Abstract
Based on practical engineering background, the string-bow pre-stressed latticed shell structure is proposed and applied to large-span indoor coal storage yard design for the first time. The static behaviors of the structure are analyzed in detail, and the seismic performances are calculated by the modal response spectrum method. The principle of pre-stress application, which ensures the supports unmoved under dead load, is also proposed. This principle not only makes the structure basically self balanced, but also simplifies the construction. The analysis results show that the pre-stressed cables enhance the rigidity of the shell, reduce the internal force and make the shell much lighter, only 3313kg/m2. Most internal forces of the struts are controlled by wind and temperature effect and the structure is more subject to the horizontal seismic effect than the vertical seismic effect. The maximum seismic force ratio of the shell reaches 0122.
