［摘要］對(duì)于具有樓板集中質(zhì)量和層間墻體分布質(zhì)量的剪力墻結(jié)構(gòu)，考慮層間彎曲變形和剪切變形，采用頻域分析方法，在層局部坐標(biāo)系中建立運(yùn)動(dòng)微分方程，運(yùn)用鐵木辛柯梁的場(chǎng)傳遞矩陣和點(diǎn)傳遞矩陣，建立頻域內(nèi)水平地面運(yùn)動(dòng)與結(jié)構(gòu)反應(yīng)的關(guān)系，進(jìn)而結(jié)合傅氏變換求出結(jié)構(gòu)地震反應(yīng)。算例表明，該方法考慮了結(jié)構(gòu)的實(shí)際質(zhì)量分布，適用于分析質(zhì)量或結(jié)構(gòu)剛度沿高度有變化的剪力墻結(jié)構(gòu)，而且符合實(shí)際情況，計(jì)算結(jié)果可靠。

Abstract:For multi-storied shear-wall structures with lumped mass at floors and distributed mass of walls along stories, equations of motion are given in local coordinates and the relationship between horizontal ground motion and structural responses are obtained through the frequency-domain approach, during which bending and shear deformations of stories are taken into account and the field transfer matrix of the Timoshenco Beam and the point transfer matrix are put into use. Then seismic response of structures can be obtained through the Fast Fourier Transform technique. Examples showed that the method takes into account the real mass distribution and is capable of analyzing shear-wall structures with variable mass and stiffness along the height of structures. The model is accordance with reality and can give rise to reliable results.

Keywords:shear-wall structure； transfer matrix； frequency-domain analysis； seismic response
