beam-on-foundation

基本解释

The rail is assumed to be an infinitely long beam (a Bernoulli-Euler beam) on a viscous-elastic foundation.
文中考虑轨道为无限长的伯努利梁，且放在粘弹性基础上。
The shape function matrices and the element stiffness matrices of the pile elements in layered media are derived by adopting the Beam - On - Dynamic - Winkler - Foundation model.
采用动力文克尔地基梁模型，推导了层状介质中桩单元的形函数矩阵和单元刚度矩阵。
The finite-length beam on elastic foundation is solved by the wavelet Galerkin finite element method. In comparison with the analytical results, the solution has better accuracy and convergence.
用此方法求解弹性地基上的有限长梁，从结果对比可以看出其解具有良好的精确性和收敛性。

地基梁
Ultimate strength design is not required and the reinforcement can be determined only on basis of allowable crack width in design of beam on foundation.
② 地基梁可不进行承载能力极限状态的计算,其配筋可由正常使用极限状态中的允许裂缝宽度来确定。
