摘要
针对传统的节点连接刚性分析和设计,选用三参数模型计算连接的初始刚度;提出了钢框架中半刚性连接的梁单元刚度矩阵,并推导了半刚性梁在集中荷载作用下固端弯矩的求解公式;给出了由单元刚度矩阵总体刚度的表达形式。
There are many defects in the conventional analysis and design of joint rigidity.The initial rigidity was calculated by threeparameter model.The semi-rigid beam element stiffness matrix is given and the fixed-end moments equilibrium for the semi-rigid beam was deduced.Added to this,the total stiffness matrix was given that based on the element stiffness matrix.
