geometry of structure meaning in Chinese
构造物的几何图式
Examples
- Fem and bem is very adapted to predict the noise level in lower frequency , but they need to describe the geometry of structure detailedly which is wasting - time for many modes in system and high frequency , wide band and random variable
有限单元方法和边界单元方法可以较好地预示低频环境噪声，但需要较为详细地描述结构的几何特性。对于时间上是随机的宽带高频分量，结构中存在大量模态的情况有时是费时的。 - Geometric nonlinear behaviors in large span cable - stayed bridges have been analyzed in this paper , which include the sag of inclined cable stays caused by their own dead weight ; the interaction of large bending and axial deformation in bending members ; and the large displacements effects . then analyzing theories and researching levels of geometric nonlinear problems of modern cable - stayed bridges have summarized . and methods of modeling cable - stayed bridges for nonlinear finite element analysis have been discussed , which are the equivalent modulus of elasticity , introducing stability functions and continuously modifying geometry of structure
本文分析了大跨径斜拉桥几何非线性的主要影响因素，包括斜拉索的垂度效应、弯矩与轴向力组合效应和大变形效应，同时对目前斜拉桥几何非线性问题的分析理论和研究水平进行了综述，相应讨论了各非线性影响因素的处理方法，即分别采用等效弹性模量法、引入稳定性函数和实时修正结构的几何位置。
