摘要
为研究不同区间、不同刚度的存在对组合刚度拱结构整体刚度的影响,文章根据能量原理,将不同区间的不同刚度统一起来,推导出等效刚度,并对临界分段点ξ的刚度变化规律进行讨论,得到等效刚度速率变化较稳定的区间,最后通过算例对等效刚度的推导及得到的规律进行了验证。
In order to study the influence of the existence of different zone and different stiffness on the overall stiffness of the composite stiffness arch structure, this article unified the different stiffness of different intervals according to the energy principle, deduced the equivalent stiffness, discussed the stiffness variation rules of critical segmentation point ξ, obtained the intervals with relative stable equivalent stiffness variation, and finally verified the deduction of equivalent stiffness and the obtained rules through the checking examples.
