【摘要】 文章分析了多侧向支撑梁的完全支撑刚度临界值。首先介绍了含有侧向支撑的薄壁构件有限元法,推导了侧向支撑带来的附加刚度矩阵,再介绍了单侧向支撑梁的临界支撑刚度的理论分析,然后利用编制的有限元程序对多侧向支撑梁的临界支撑刚度进行了算例求解。更多还原

【Abstract】 This paper analysed the ultimate complete brace’s stiffness of multiple-lateral-braces-beam.First investigates the thin-walled member’s FEM including the lateral braces and induces the additional stiffness matrix.Then analyses the ultimate stiffness of single brace’s beam in theory.At last analyses the ultimate stiffness of multiple brace’s beam by FEM.更多还原
