Jianzhu Gangjiegou Jinzhan, 2021 为研究圆锥形中空夹层钢管混凝土构件压弯剪受力性能,利用ABAQUS有限元软件建立了数值分析模型,计算了横向剪力-位移关系曲线,分析了构件破坏模态,提取了各组件相互作用力及荷载分配曲线;最后对影响圆锥形中空夹心层钢管混凝土构件压弯剪受力性能的主要参数进行了数值计算。结果表明:空心率、锥度、混凝土强度等级对圆锥形中空夹层钢管混凝土压弯剪构件的横向剪力峰值影响甚微,剪跨比、轴压比、钢材强度等级以及内、外钢管径厚比对其影响较为显著,且当内部钢管径厚比大于60时,极限承载力的增幅较小。

钢压弯构件面内等效弯矩系数取值的改进(下)——端部有侧移的构件
Jianzhu Gangjiegou Jinzhan, 2010 本文继上篇之后论述端部有侧移的压弯构件的面内等效弯矩系数。首先推导弹性悬臂构件等效弯矩系数的理论计算公式,包括自由端承载和杆内荷载的不同工况,并在此基础上推出近似计算公式。其次,用有限元方法计算悬臂压弯构件的弹塑性稳定承载力,并以此为基础对弹性分析的结果进行校验。校验表明弹性等效转换得到的公式可以可靠地应用。同时,还论证了公式可以应用于端部有转动约束的框架柱。最后讨论框架内力采用二阶分析时的柱的βm系数,指出《钢结构设计规范》(GB 50017-2003)的规定有所误解。
