分散筒体系的概念和初步研究

Study on the concept and preliminary of dispersive tube system

随着我国经济与城市化建设的飞速发展和人口地不断增加,超高层结构不断被应用到工程实际中。但是,超高层建筑的发展受到造价成本和抗震安全性的约束。为了减小超高层结构在地震作用下侧移,增大其抗震承载力,综合对比框架核心筒结构和剪力墙结构的优缺点,总结提出分散筒结构。有限元软件ABAQUS和ANSYS时程分析可以很好地模拟实际工程框架核心筒体结构和剪力墙结构的抗震性能,通过有限元软件仿真对比发现分散筒结构抗震性能更加优越,比其他两种结构更适于在实际超高层工程中广泛应用。

Super high-rise structures are being more and more popular in practical engineering with the rapid development of Chinese economy and urban construction as well as the continuous increase of population.However,the development of super high-rise structures is restricted by cost and the earthquake safety.In order to reduce the lateral displacement of super high-rise structures under seismic action and to increase the seismic bearing capacity,frame core tube structure and shear wall structure were compared comprehensively.A dispersion tube structure was proposed.ABAQUS and ANSYS could be used to simulate the seismic performance of frame core tube structure and shear wall structure.A dispersion tube structure has a more superior seismic performance than the other two through simulation and thus is more suitable in super high-rise buildings.
