薄壁斜交箱梁的斜形板梁有限单元法
An inclined plate beam finite element method of spatial computation for skew thin walled box girder
【摘要】 根据斜交箱梁力学行为为梁特征的特点 ,将围成闭口截面箱梁板件视为板梁 ,然后借助斜坐标系来描述各板件子单元位移模式 ,由此提出了薄壁斜交箱梁空间计算的斜形板梁有限单元法
【Abstract】 The deckle boards of skew box girder are taken as inclined plate beams according to the box girder mechanics is the beam characteristic, then the displacement field of inclined plate beams is constructed by means of local inclined coordinate,and an inclined plate beam finite element mehod is presented.
