钢框架结构稳定性分析中的传递矩阵

Transfer matrix of stability analysis of steel frames

通过反映杆件两端状态变量的梁单元、柱单元和支座处的传递矩阵的推导,用合并变量的方法,进而推出钢框架结构稳定性分析中的的总体传递矩阵。解决了用传递矩阵法分析多高层钢框架结构稳定性的关键问题。

Beamelement, columnelement transfer matrix that indicate state parameters of two ends of bars and transfer matrix that indicates internal force and displacement variety of every braces are derived, then the total transfer matrix that solves state parameters of every story is obtained. The key problem is solved so that Transfer Matrix Method is introduced to study total stability of steel frames.
