[提要]  介紹一個(gè)在水平力作用下，框架側(cè)移新的近似計(jì)算方法。系用節(jié)點(diǎn)桿端綜合抗彎剛度導(dǎo)出的A值法。不但可計(jì)算框架因彎曲及剪切變形產(chǎn)生的側(cè)移；而且還可計(jì)算因軸向變形產(chǎn)生的側(cè)移。經(jīng)比較精度較高。
[關(guān)鍵詞]  側(cè)移 軸向變形 綜合抗彎剛度 A值法

A new approximate method, A-value methocl, for calculating sidesway of frames subjected to horizon-tal external forces is presented. It can calculate sidesways induced by bending, shearing, and axial deformations. This method has been proved to be a more accurate one as compared with the others訪(fǎng)use.
Keywords: sidesway; axial deformation; synthesize bending stiffness factor; A- value method
