摘要
本文给出的可用于连续曲梁空间分析的样条有限条法计算公式,为有各种边界支承和中间支承的结构分析提供了快速、有效的计算方法,具有广泛的工程实用价值。文中通过对一个双跨带支座隔墙的梯形曲线箱梁模型的实测结果与样条有限条法计算值的比较,验证了本文方法的可靠性和适用性。
Formulas on spline finite strip method for three dimensional analysis of continuous curved girders are given in the paper, providing a rapid and efficient numerical method for the analysis of structures with various types of end and interior supports. The reliability and suitability of this method is demonstrated by comparing the calculated values with the experimental results for a two-span continuous curved trapezoidal box girder with diaphragms at every support.
