[提要] 對作者提出的一種抗震自控結(jié)構(gòu)——帶豎縫剪力墻作了非線性地震反應分析。分析中運用了具有足夠精度的帶縫剪力墻結(jié)構(gòu)的簡化計算模型，使計算大大簡化而結(jié)果的可靠性不減，旨在考察帶縫剪力墻的實際動力反應和抗震自控效果。計算結(jié)果表明，帶縫剪力墻中縫槽間連梁的不斷屈服能明顯減弱整體結(jié)構(gòu)的動力反應；而且通過設計連梁的屈服強度值，能優(yōu)化控制帶縫剪力墻的地震反應。
[關鍵詞] 地震反應 帶縫剪力墻 鋼筋砼 連梁 非線性A reinforced concrete slit shear wall is a new breed of earthquake resistant structure recently proposed by the authors. In this paper, the seismic responses of the slit shear walls under the shake of earthquake excitation heve been dealt with. Based on a simplified structural model, which is shown to have a sufficient accuracy for the real slit shear wall structure, the analysis focuses on the influence of nonlinear behavior of the connecting beams between the slits on the dynamic performance of the whole slit shear wall structure. It has heen found, the yielding of connecting beams in a slit shear wall can provide significant improvement in reducing the structural responses, and by choosing an appropriate strength value for the connecting beams,it is possible to optimize the seismic response of the slit shear wall.
