Lag Pendulum Model and Its Application in Wind Resistance Stability of the Structure

Abstract

Air resistance in the study of architectural design and other sports is an important factor that cannot be ignored. On the basis of the lag pendulum model formed by motion resistance, from the aspects of geometric structure we analysis the wind resistance stability of cable-stayed bridge and Guangzhou tower. Results showed that the tilt design of sola cable can effectively improve the wind stability of the bridge; the outer barrel tilted inclined column and brace structure in Guangzhou tower can effectively resist strong wind resistance, outer barrel rigid node can withstand wind loads, resistance to bending moments. With the lag pendulum model, the paper validation sola bridge and Guangzhou tower, and the rationality of the design which make sure the safety of structure.
