摘要: 為研究構(gòu)件 P-δ 效應(yīng)對(duì)超高通高構(gòu)件的影響，以重慶某超高層項(xiàng)目為例，對(duì)超高通高墻的承載力和穩(wěn)定性進(jìn)行了全面的分析研究，并對(duì)通高墻提出了相應(yīng)的構(gòu)造措施。分析結(jié)果表明，對(duì)超高通高墻，P-δ 效應(yīng)會(huì)顯著放大構(gòu)件內(nèi)力，因此，除按普通豎向構(gòu)件驗(yàn)算其承載力以外，還應(yīng)考慮 P-δ 效應(yīng)對(duì)通高構(gòu)件內(nèi)力的增大作用。采用特征值屈曲分析、規(guī)范規(guī)定的方法和幾何非線(xiàn)性屈曲分析等不同的方法計(jì)算通高墻的穩(wěn)定性，分析結(jié)果表明，本項(xiàng)目中通高墻穩(wěn)定承載力滿(mǎn)足設(shè)計(jì)要求，通高墻穩(wěn)定性有較大富余。

Abstract: In order to study the influence of P-δ effect on super-high cross-layer component,taking a super high-risebuilding in Chongqing as an example,a comprehensive analysis on the bearing capacity and stability of super-highcross-layer walls were made,corresponding structural measures of cross-layer walls were put. The results show that forsuper-high cross-layer walls,P-δ effect will significantly enlarge the internal force of members，therefore,in addition tochecking its bearing capacity as an ordinary vertical member,P-δ effect should also be considered on the increase ofinternal force of cross-layer members. Different methods such as eigenvalue buckling analysis,specification method andgeometric nonlinear buckling analysis were used to calculate the stability of cross-layer walls. The analysis results show thatthe stability bearing capacity of cross-layer walls in the project satisfy design requirements,and the stability of cross-layerwalls have a large margin.

Keywords: super high-rise building； super-high cross-layer wall； P-δ effect； stability bearing capacity； eigenvaluebuckling analysis； geometrically nonlinear buckling
