Abstract:

?为了给工程设计人员提供简单、易懂、实用的薄壁加劲钢桥墩抗震设计理论和评估方法,提出了基于纤维梁单元的简化抗震评估方法。以薄壁加劲箱形悬臂钢桥墩为研究对象,首先通过建立基于壳单元的有限元模型并与试验进行对比,验证了双线性随动强化模型的有效性和壳单元有限元模型的精确性;其次通过12个数值算例,评估了3种不同应力-应变关系对薄壁加劲箱形钢桥墩的纤维梁单元模型Pushover分析所得极值点的影响,并与壳单元有限元模型的结果进行对比,验证了考虑局部屈曲效应的简易应力-应变关系的可行性。结果表明:使用提出的纤维梁单元模型和对局部屈曲进行简化考虑的修正双线性应力-应变关系,可以比较精确地评估薄壁加劲箱形钢桥墩的抗震性能。
