Analysis of Wind-induced Response and Torsional Effect of High-pier Lattice Support
In view of the length,small diameter,light overall structure is easily affected by wind load.The fine finite element model is used to establish the four-legged and six-legged lattice high scaffold by finite element simulation,and the model is corrected by time domain method to obtain the displacement of the lattice high scaffold under the ten-level wind load,the wind vibration coefficient is obtained and the torsional response and torsional wind load are analyzed.The results show that the maximum displacement of the four-leg single-column high bracket is 85.9 mm in the tenth wind,and the maximum displacement of the six-leg high bracket is 42.8 mm in the tenth wind.The fine finite element model can well simulate the influence of wind load on the rod under two different working conditions.
