摘要: 本文分别以柔度法与有限元素法所推导出之空间曲梁元素,经由特征分析作一精确性之比较。此外,传统桥梁结构在进行动力分析时,一般仅就同步支承输入效应予以探讨,本文将针对直线桥梁与曲线桥梁,进一步考虑多支承输入之效应。结果显示,一般同步支承输入效应未必保守、安全,因此桥梁多支承输入效应之评估则有其必要性。
In this thesis, the space curved beam element is derived based on the method of flexibility matrix and the finite element method that are compared by characteristic analysis. Moreover, traditional bridge structural dynamic analysis processes with identical support excitation, the effect of multiple support excitation takes into account for continuous straight bridges and continuous curved bridges in this thesis. In the results, it is not conservative and not safe in the analysis of identical support excitation, so it is necessary to estimate the effect of multiple support excitation in the bridge dynamic analysis.
