摘要
利用有限元软件ANSYS/LS-DYNA建立多个跨度为6m的标准HM450×300型钢梁有限元模型,分析不同药量爆炸荷载作用下,设置不同加劲肋对型钢梁整体位移及局部变形的影响。分析结果表明,同时设置横向+纵向+短加劲肋可有效减小爆炸荷载作用下,型钢梁的整体位移及局部变形。
Using ANSYS/LS-DYNA software,some 6 meter standard HM450×300 steel beam finite element models were established.Influences of global displacement and local deformation of those beams by setting different types of stiffeners under blast load with different charge was analyzed.The analysis results indicated that setting transverse stiffeners,longitudinal stiffeners and short stiffeners could reduce global displacement and local deformation of those steel beams under blast load effectively.
