Jianzhu Gangjiegou Jinzhan, 2021 设计了复式钢管混凝土钢梁半穿心加肋加腋型节点,制作了4个梁柱试件组合体进行低周往复加载试验,并采用ABAQUS有限元软件建立了节点数值分析模型。半穿心节点刚度较大,破坏模式主要为梁端塑性铰破坏,节点试件的滞回曲线呈明显的纺锤形,耗能性能较好,有限元分析结果与试验结果吻合较好。利用有限元模型研究了节点构造、几何参数和材料参数对半穿心节点的破坏模式和承载力的影响。参数分析表明:梁柱线刚度比及轴压比对节点初始刚度影响显著;轴压比和钢梁强度对节点极限承载力影响较大;而节点的变形能力受轴压比影响较大 ...

Imaging anatomy and hemodynamic simulation of the extracranial segment of vertebral artery [PDF]
, 2015 研究背景:椎-基底动脉系统是脑组织供血的重要血管之一，主要为脑干、小脑及双侧大脑半球后1/3供血。双侧椎动脉（vertebralartery，VA）主要发自于锁骨下动脉，于C6水平入横突孔，穿行于上6颈椎横突孔内，经枕大孔入颅；在脑桥前下合并为基底动脉，其寰枢段走行弯曲，周围解剖结构复杂。深入研究椎动脉的相关形态及血流动力学，对提高后循环缺血诊断和治疗具有重要的临床意义。 目的：（1）利用多排螺旋CT（multi-slicespiralCTangiography，MSCTA ...
