Static Wind Load and Gravity Coupling Effect of Tall Structure
The cantilever beam model of tall building structure which includes lateral wind load and vertical gravity coupling has been established in the paper. The form of finite difference has been concluded from equations of the model acted on static wind load. Amplified coefficients of bottom moment and top displacement are calculated and analyzed. The result shows that gravity second order effect of tall buildings will be enhanced when ratio of gravity rigidity or ratio of bending and shearing rigidity increase.
