半刚性钢框架的内力性态分析

Characters of Internal Forces in Semi-rigid Steel Frames

导出了半刚性钢框架结构分析的一般方程 ,讨论了半刚性简单门式刚架的内力特征 ,指出了欧洲规范[4] 刚柔性界定可能导致的内力误差及其存在的不协调性 ,同时提出了改进刚柔性界定的建议。

The general equations for semi rigid steel structures are deduced.Some characters about internal forces in semi rigid frames are brought to light.The possible latent errors and incongruity caused by the definition in Eurocode 3 are pointed out.A suggestion on classification of semi rigid points is made for the frame.
