Dynamic Behavior of Extra-High Building with Wind Load and Gravity Coupling Effect

Abstract:

Wind-gravity coupling effect(WGCE) is an evident phenomenon of extra high buildings. Cantilever model of tall building structure which includes bending and shear distortion is established in the paper. The equations of wind load and gravity coupling have been concluded and are dispersed into difference form. Amplitude frequency characteristic of the structure and vibration acted by simulated wind load are studied though calculation by Wilson-θ method. The result shows that gravity second order effect of extra-high buildings will be enhanced when ratio of gravity rigidity or ratio of bending and shearing rigidity increase.
