| 摘 要： | 为了进一步论证框架柱P-δ效应规律，以无侧移单元封闭框架为研究的出发点，回顾了由数值分析结果总结出的无侧移单元封闭框架柱二阶效应规律，提出了二阶效应分析中的二阶内力方程和基于转角位移方程的附加位移法，揭示了框架整体二阶效应对框架内力的影响规律，并得到无侧移单元封闭框架二阶效应的解析解，解析法得出的无侧移单元封闭框架柱二阶效应规律与数值分析结果协调．从理论上证明了无侧移单元封闭框架柱二阶效应规律的严密性．

| Abstract: | The regular pattern of second order effects according to numerical analysis results in non-sway closed cell frame columns is reviewed . The second order internal force equation and additional displacement method based on the turn-angle equation are provided in second order effects analysis. The analytic solution of second order effects in non-sway closed cell frames is solved by this method, which has proved that the regular pattern of second order effects in non - sway closed cell frame columns is exact. |
