[提要] 綜述了框剪結(jié)構(gòu)在水平力作用下計算方法的發(fā)展歷史，結(jié)合工程應(yīng)用，提出了一種擬彈性地基梁法，推導(dǎo)了該法的計算公式，并編制成軟件。通過用該軟件對算例進(jìn)行分析比較，驗證了該算法正確、簡單適用，又由于可考慮結(jié)構(gòu)的高振型影響，故該法精度優(yōu)于連續(xù)柵片法。
[關(guān)鍵詞] 框剪結(jié)構(gòu) 振型組合法 鏈桿法 剪切 彎曲 變形 高振型This paper analysizes and summarizes the development of computing method for tall building frame- shear wall structures supjected to lateral loads, presents a pseudo-elastic foundation beam method according to engineering. A series of formulas were proposed and carried into the computer programs. This method can apply the mode-superposition method to take the influence of high vibration mode into consideration, so its computation is more accurate than continuous-grid methods.
Keywords: frame - shear wall structure; mode - superposition; rod method; shear; flexural; deformation
