| With the rapid development of China’s economy,the high-rise building structure in the major cities gradually increased.Many cities in high-rise building as a landmark of the city,so how to evaluate and ensure the mechanical characteristics of the high-rise buildings,especially reliability under earthquake,is a hot topic in seismic design of high-rise building.In addition,with the development of advanced building design concept,building structure type more and more complex,the function more and this presents a challenge more diverse,more on the design of high-rise building.In this paper,a high-rise building,combined with ANSYS simulation software,the mechanical characteristics of the high building analysis based on ANSYS simulation,this paper has done the following work:Introduces the development status of seismic design of high-rise building at home and abroad,and the background and significance of this thesis.Based on the engineering background of a high-rise building in ANSYS,a finite element model of high-rise building is established,and analysis of mechanical properties of high-rise buildings in different wind loads and different material constitutive equation is discussed.The results show that the high-rise building the elastoplastic constitutive model closer to the actual situation in different wind load under lateral load structure strength and positive load.In addition the elastoplastic constitutive model based on the structure of high-rise building for the transient time history analysis,the three kinds of seismic waves under time effect were discussed.The main risk direction of the high-rise building is Y,for the construction of the level of short.From the interlayer displacement and interlayer displacement angle analysis.The tenth middle layer is relatively weak,the three wave of the calculated results are consistent.The larger shear area occurred in the lower layer,because the stiffnessof the building area is the mutation of the lower layer,each layer of the structure were the same as those of the rest of the same height.According to the results of the calculation,we should pay attention to the construction of the structure of the short direction,because the direction of the shear wall is relatively weak,at the same time can be considered in the middle of the 10 floors do a certain structural strengthening measures. |
