| 摘 要： | 定义了带弹性约束混合梁单元的位移形函数，基于有限变形理论推导了混合梁单元的一阶及二阶刚度矩阵以及混合梁单元的平衡方程。将混合梁单元并入常规的框架设计程序中，实现了对半刚性框架的非线性分析，最后编制程序对一榀单跨双层半刚性框架进行了非线性分析。 |
| 关 键 词： | 半刚性框架 非线性 有限元分析 |

| Abstract: | The displacement shape function of hybrid beam element was derived.And based on the theory of finite deformation,the first-order and the second-order stiffness matrix and the equilibrium equation were got.The nonlinear analysis of steel frames with semi-rigid can be practiced through merging the hybrid beam element into the ordinary design programs.At last the paper conducted second order analysis for a one-bay,two-story semi-rigid plain steel frame. |
| Keywords: | semi-rigid steel frames nonlinearity finite element analysis |
