Wind-induced response and equivalent static wind loads of double-layer reticulated shell structures

To systematically research the wind-resistance of double-layer reticulated shell structures widely used in various large public buildings, the wind-induced response of a typical double-layer reticulated shell was analyzed in this paper. The results show that for this kind of rigid structure, the background response contributes much more significantly than resonant response. Based on this condition, an equivalent static wind loads representation method which differs from the current code was put forward. Then the efficiency of this method was demonstrated on the basis of a numerical example.
