半刚性钢框架二阶弹性静力分析的QR法

采用梁柱法和稳定函数推导了梁柱结构考虑二阶效应及梁柱半刚性连接时的单元刚度矩阵，并用Kishi-Chen幂函数模型描述了半刚性连接的特性，采用B样条函数及正交多项式乘积的线性组合，构造了QR法的结构整体位移函数，通过QR法样条离散，建立起QR法的计算格式，并编制了相应的计算程序。

QR method for the static elastic analysis of steel frame with semi-rigid connection

Using the theory of beam-column and stability function to derive the element stiffness matrix which considers second-order effect and the beam-column semi-rigid connection,and using Kishi-Chen power function to describe the nonlinear behavior of semi-rigid connections.Using the linear combination of B-spline function and orthogonal polynomials,the structure whole displacement function of QR method was constructed.Through spline dispersion of the QR method,the QR method computational scheme was established,a...
