WIND VIBRATION RESPONSE FOR A NEW TYPE OF RETICULATED SHELL

摘要

Plate-cone reticulated shell is a new type of reticulated shell with good mechanical behaviour and technical economy. Wind-induced vibration response characteristics of plate-cone reticulated shell are studied, the fluctuation wind loads are simulated by using the wave superposition method in the paper. According to the structural behaviour of plate-cone reticulated shell, by using the software ANSYS, wind resistance time domain analysis of plate-cone reticulated shell are carried out through simulating wind field variation around the plate-cone reticulated shell. After comparing the wind dynamic vibration results of the models with different material, some important conclusions for plate-cone reticulated shell are obtained for practical design.
