Influence Of Inclined Columns And Measures Researchment For High-rise Building

Tall building with inclined columns have attracted the eyes of modern architectsfor its unique glamour. Inclined column, as a key component of the tall building, relatesto security of the whole building, so it is critical. This article takes a A level high-riseframe-core wall structure with inclined column as an example, makes use ofcommonly-used finite element software ANSYS, ETABS and MIDAS Building, toanalyze and study the influence and treatment measures for inclined columns whichwere fixed up in the ultra-high building. And this paper has provided some referenceconclusion for the practical engineering.In the practical engineering, the inclined columns are not always decorated alongthe whole tall building, so this paper studied the oblique columns’ deadline way firstly.This paper has analyzed the overall performance and internal force for the model of thetwo different inclined columns’ deadline way, and analysis showed that the deadlineway of inclined columns indirect connection with frame column through frame beams isgood for the whole structure.Then, the article made use of response spectrum method to analyze holisticbehavior for the straight column frame-tube structure and inclined column frame-tubestructure, it also analyzed the loading conditions for and the floor of tops of the inclinedcolumns. And the article made clear the effect of inclined columns. Then, this paperanalyzed four mearsures’ contribution of reducing shear of the beams,which areconnected with inclined columns, and the results show that: reducing inclined columnsection can effectively reduce the beams shear,which is helpful for structure design.Finally, this paper carried out dynamic elastoplastic time history analysis for thestructure under rare event of earthquake. Analysis showed that overall site performanceof the structure met the requirements of technical specification for concrete structures oftall building, all the beams connected with inclined column were basically entered intothe steel yield state,and shear wall, frame columns and inclined columns were in elasticstate. This paper also carried out dynamic elasto-plastic analysis on the structure modeltaken the treatment measures. Then the paper compared the results for them, analysisshowed that after the structure took the processing measures, more frame beams enteredinto the steel yield state, that was, structure had more frame beams to energyconsumption, which was helpful to resist earthquakes.
