Abstract

When the building facade has unevenly distributed rigidity and the top thereof has protrusions or the facade rigidity is suddenly changed, the building top can easily have significantly increased amplitude and horizontal displacement under the action of earthquake. The above phenomenon is called whipping effect which is unfavorable for the stress, displacement and deformation of the structure top, so the whipping effect is particularly obvious in the aseismicity of the high-rise building. To research the occurrence essence of the whipping effect and avoid the whipping effect, it is necessary to firstly introduce the whipping effect and then analyze the difference between the whipping effect and the cantilever construction according to the characteristics of statically indeterminate structure and determinate structure; afterwards, it is necessary to adopt the finite element computational analysis software for modeling to simulate the application of dead load, live load and seismic load onto the three different high-rise building structures in order to calculate maximum inter-floor displacement (angle), (acceleration) speed, shearing force and bending moment, analyze and compare the displacement, movement and stress thereof; finally, the following conclusion is obtained: to reduce the influence of the whipping effect on the high-rise building, the facade rigidity stress of the high-rise building shall be constant or evenly changed.
