Jianzhu Gangjiegou Jinzhan, 2018 铝合金板式节点网壳是一种典型的半刚性节点网壳。采用ANSYS有限元软件对铝合金板式节点网壳弹塑性稳定性能进行了有限元分析。建立了考虑节点刚度的杆件单元模型。采用Combin39单元对节点非线性弯曲刚度进行模拟。分析了节点刚度对网壳失稳模态、应力分布和极限承载力的影响。研究发现,节点的非线性弯曲刚度对网壳整体稳定性能具有削弱作用,其削弱作用随着网壳矢跨比的减小而加大。最后,为了了解节点刚度四折线模型中各参数对网壳稳定性能的影响而进行了参数分析。研究表明,网壳极限承载力随着滑移弯矩和嵌固刚度的减小而降低 ...

Jianzhu Gangjiegou Jinzhan索塔锚固区的受力分析通常采用实体有限元单元进行，然而由于其结构复杂、种类繁多，不易被一般工程设计人员使用。为此，结合某斜拉桥的实际工程案例，分析了内置式钢锚箱锚固体系的传力特点，提出了一种基于平面框架理论的简化计算方法，并利用非线性的分析方法建立了锚固区ANSYS有限元模型以修正公式。结果表明修正前简化公式计算结果与有限元模型计算结果之间的误差在10%左右；考虑到塔壁厚度、索塔计算高度以及锚箱侧板厚度的影响，使用折减混凝土弹性模量的方法来补偿和修正桥塔应力分布 ...
