Seismic Behavior Researches On High-rise Building With Thick Transfer Slabs

Based on the state of the art of researches and applications about high-rise building with transfer floorslab, The effect of earthquake-resistant behavior and the dynamic characteristics in the tall building structures with transfer floorslab was researched in this dissertation. In combination of actual project—No.2 building of Wuhan XinShiJi which is such a typical complicated high-rise building with transfer floorslab are analyzed by using large finite element program ANSYS . Furthermore, the dynamic properties of the structure of whole structure under two factors—mass and rigidity is studied. The main achievements of the dissertation are expatiated as the following:1) In combination of actual project, create finite modal .studying the characteristic of displacement acute and distribution of shear force by the modal and dynamical analysis, and give some advices by the result.2) Discussing the earthquake—resistant behavior of whole structure under two factors—mass and rigidity. The analytic results indicate that mass and stiffness of transfer floorslab are changed relatively less.3) Using the solid element analyze the thick slab, and researching the regularities of deformation and stress distribution in the transfer floorslab on the seismic performance. And pointing the refroze of transfer floorslab is complicated.The dissertations gives the commonly conclusion and rule and provide a theoretic base for the seismic design, and also have vast reference values for the design of the similar complicated tall building. At the same time, it indicates that ANSYS is one of most famous finite element software, and it can solve complex and complicated engineering problem.
