局部刚度 meaning in English
local rigidity
Examples
- Method for identifying local stiffness of linear structures under random excitations
随机激励下的线性结构系统局部刚度参数识别 - Numerical examples are presented in succession and prove the proposed method to be robust and effective
结构系统为线性系统； 2损伤仅仅影响结构局部刚度，而结构质量不受损伤影响。 - Theoretically speaking , certain crack or damage in structure will result in reduction of stiffness in the local part , and also will result the stress and strain concentration in the same part
理论上,结构的局部裂缝或损伤必然会导致结构局部刚度降低,从而使应变在损伤处发生集中,应变模态振型数值发生突变。 - The results indicate that the boundary conditions have negligible effect on indent depth estimate , and the stiffness of laminates in contacting area has the major effect on the indent depth
结果表明,不同边界条件下相同压痕力对应的压痕深度几乎相同,边界条件对压痕的影响微乎其微,板的压痕更主要取决于接触区板的局部刚度。 - Thirdly , subspace iterative method is adopted in the paper , and natural periods and modes of preceding fifteen steps of zhongshan no . one bridge are solved , dynamic characteristics of this kind of structural system are obtained , inherent link between dynamic characteristics and structural rigidity is discussed deep , the viewpoint is provided that dynamic characteristics of a structure are considered as important basis whether structural scheme is rational ; in addition , the author brings out some own views and opinions about calculational methods of prestress value of different sorts of tie rods , simulation of local rigidity region , foundation of a local finite element model of a node
另外，提出在施工阶段中某些构件的应力有可能比成桥状态的应力还大，需防止在施工状态中构件因强度不足而破坏；再次，采用于空间迭代法，求解了拱式组合体系桥梁的自振周期和振型，得出该种结构体系的动力特性，深入探讨了动力特性和结构刚度之间的内在联系，提出了把结构的动力特性作为判断结构方案是否合理的重要依据。此外，本文还就系杆预应力值的确定方法、局部刚度区域的模拟、节点局部有限元分析提出了作者的见解和看法，对解决类似问题得出了一些有参考意义的结论。
