摘 要：
板梁系是桥梁中一种常用的上部结构形式,其计算常采用染格法,有限差分法,有限元法和有限条法等。有限元法能灵活地适应结构形式,较好地逼近实际情况。但其计算工作量大,在小型计算机上难以实施。有限条法可将三维问题化为一维或

摘 要：
In this paper, a spline segment clement for skewed plate-beam syst-ems is developed. The displacement model, which uses cubic B spline functions in transcurrent direction and segment polynomials in longit-udinal direction for each spline basis, can be written in a product form. Its two longitudinal boundaries are free. The numerical results show a good precision. It's convenient to apply to multiple span con tinuous plate-beam systems as slab beam bridges with variant sections.
