The Design Of The Inclined Column Frame Of An Office Building - Core Tube Structure

With the improvement of design theory, the emergence of new materials and improve construction technology, making the shape of diverse, complex shape of the tall building became a reality. With inclined column practical engineering frame-core tube system more and more, while the current specification does not specify for inclined column, so still need specific analysis and structural design calculations for different practical engineering.In this article, Midas software is used to compare the overall performance of the inclined column frame-core tube and the common vertical column frame-core structure system. Analysis showed that the impact of this engineering on the inclined column structure overall performance is almost negligible. But, in contrast, inclined column greater impact on the performance indicators in its inclined plane, outside the influence of the inclined plane is almost zero.Comparative analysis of floor member forces involved in the actual work is then considered in this article. Analysis showed that the existence of inclined column will produce more complex than ordinary straight column model under the force of the inclined column, beam and floor, especially in the angle of inclined column occurred change floors prone to stress concentration phenomenon is particularly serious. Then, this article provides a method to reduce the column Inclined impact.Finally Inclined Column frame-core tube structure of the nonlinear static analysis under rare earthquake, the analysis indicates that the structural system to meet the "rare earthquake not fall" the fortification level requirements.
