Time History Analysis In The Frame-Concrete Wall Stucture Of The Horizonal Strenthened Storey

With the development of the building height, the influence of lateral force has become relatively stronger and lateral distortion larger and larger. It is an important subject in high-building structure designs that how to search for the best scheme so as to control the lateral distortion of the structure when it is influenced by wind or earthquake. In recent years, some experts have proposed that the horizontal strengthened storey structure should be adopted in strengthening the cooperative work between tube structure and the columns in the peripheral layer to control lateral distortion, namely, to put horizontal cantilever with hard quantity between the tube and the frame, or set circumjacent zone with hard quality along the peripheral frame, which is the most commonly used structural system of frame-concrete wall structure with horizontal strengthened storey. It is an effective way to stop the structure side-moving against the influence of wind by setting the horizontal strengthened storey. When come to the influence of earthquake, this designs will cause the sudden change in the quality and internal force of the structure and thus forms a weak layer, which will make it difficult for the yield mechanism of the structure to carry out its extending bending system.By applying the FEA analysis software SAP2000 , in setting Tree-dimensional FEA analysis modal and adopting dynamical time history analytic method to make elastic-plastic time history analysis on the model, this thesis gets the reacting rule of the structural displacement and the internal force when influenced by the earthquake, and find out the possible position of stress converging and plastic distortion converging and other weak points. Thus the anti-earthquake quality of the structure can be improved by strengthening the restrictive structural corrugated steel bar in the weak parts.By applying time history analysis in the three-dimensional model of the frame-concrete wall structure of the horizontal strengthened storey and aiming at different designs for the strengthened storey, this thesis has got the displacement of the structure and the internal force reaction under the influence of earthquake and the influencing rule that the horizontal strengthened storey...
