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。
This paper introduces the phenolic electro-mechanical test model test of a fifteen-layer bottom column with a large column spacing. The peripheral pitch of the outer cylinder of the bottom layer of the model is twice that of the top column, but some measures are taken in the design of the model to maintain the space effect of the cylinder. In the experiment, the internal force distribution of the model under the action of an inverted triangular lateral load was measured, and the load distribution of the inner and outer cylinders and the lateral displacement of the structure at the bottom of the structure were obtained. According to the test results, the characteristics of the distribution of internal forces and the distribution of the load distribution in the structure of the bottom pillar with a large distance from the high-rise drum are discussed. The feasibility of the scheme of the bottom pillar with a large distance from the cylinder is discussed, and it is necessary for the application of this kind of structure in practical projects. data of.
