（煙臺大學土木系 264005）[提要] 從結構二階效應產(chǎn)生等效附加剪力的角度出發(fā)，通過對幾何級數(shù)求和，推導出結構二階效應的簡化計算方法。該法實用于框架及框架-剪力墻結構，通過算例與精確法進行了比較。
[關鍵詞] 結構分析 二階效應Based on the equivalent shear resulted from the second order effects in structures and the sum of geometrical series, a simplified method for the second order effects in structures is presented, which is applicable to either frame or frame-wall structures. The results from the numerical examples are satisfactory as compared with those from the precise method.
Keywords: structure analysis; second order effects; frame; frame-shear wall
