底层大柱距筒中筒结构的模型试验研究

THE MODEL TEST RESEARCH OF TUBE-IN-TUBE STRUCTURES WITH WIDELY SPACED PERIPHERAL COLUMNS ON THE GROUND FLOOR

  • 摘要: 本文介绍了一十五层底层大柱距筒中筒结构的有机玻璃电测模型试验。模型底层外筒周边柱距为上部柱距的两倍,但为保持筒的空间作用特性,模型设计中采取了一些措施。试验中量测了模型在倒三角侧向荷载作用下的内力分布,得到了结构底部两层内外筒的荷载分配及结构的侧向位移。根据试验结果,讨论了底层大柱距高层筒中筒结构内力分布及荷截分配的特点,论述了底层大柱距筒中筒结构方案的可行性,为该类结构在实际工程中的应用提供了必要的资料。

     

    Abstract: In this paper,a plexiglass model test is represented.The 15-story model is a tube-in-tube structure with widely spaced peripheral columns on the ground floor.The center-to-center column spacing on the ground floor is twice as large as that on the typical floor.Some emethods were used in order to keep the tube action of the structure. The deflection curve and the load distribution of the structure subjcted to lateral loads were obtained.Based on the results of the model test,the behaviour,of the tube-in-tube structures is discussed, which is of concern in the building design.
