| 摘 要： | 理想化结构单元法(ISUM)已经成为评估结构系统中承受载荷能力的一个有效工具.本文给出了最新的ISUM板元公式,并考虑了双轴向推力和横向载荷对板元的加载.为了精确地模拟加筋板的性能,分别用梁-柱元和板元制作了肋材和板材的模型.与有限元分析(FEA)的比较表明该方法对解决加筋板在横向压力和推力载荷下的问题是适用的.对箱形桁材的四点弯曲试验的分析表明与试验数据吻合良好. |

| Abstract: | The Idealized Structural Unit Method (ISUM) has become a valuable tool for assessing the load carrying capacity at the structural system level.In this paper,the formulation of the most recent ISUM plate element is given.Application of biaxial thrust and lateral loads to the plate element is considered.To simul ate the behaviour of stiffened plates accurately,stiffeners and panels are model led individually by beam-column elements and plate elements.Comparisons with FEA demonstrate the applicability of the approach to stiffened plates under lateral pressure and thrust.The analysis of a four-point bending test of box girder spe cimens shows favourable agreement with experimental data. |
| Keywords: | ISUM ISUM plate element beam-column element stiffened plates ultimate strength lateral pressure box girder |
