摘要: ?？陔p子塔?南塔位于地震高烈度與強(qiáng)臺(tái)風(fēng)區(qū),結(jié)構(gòu)設(shè)計(jì)存在較大挑戰(zhàn),其整體穩(wěn)定及構(gòu)件穩(wěn)定承載力驗(yàn)算是其中的重要內(nèi)容. 首先采用倒三角分布荷載、風(fēng)荷載和地震作用三種荷載分布形式計(jì)算了結(jié)構(gòu)的彈性等效側(cè)向剛度,并據(jù)此得到了結(jié)構(gòu)的剛重比和 P?Δ 效應(yīng)的影響,結(jié)果表明,結(jié)構(gòu)具有較好的抗側(cè)剛度和整體穩(wěn)定性能. 使用 MIDAS Gen 軟件進(jìn)行了結(jié)構(gòu)整體屈曲分析,進(jìn)一步印證了結(jié)構(gòu)具有良好的整體穩(wěn)定性能. 通過彈性屈曲計(jì)算了巨型柱及 RCFT 中柱的屈曲臨界荷載,并使用歐拉公式反算了計(jì)算長(zhǎng)度系數(shù).

Abstract: Haikou Twin Towers?South Tower is located in the area of high seismic fortification intensity and strong typhoon,which is a large threat to structural design. The checking calculation of the overall stability and component stability bearingcapacity are important contents. Firstly, the elastic equivalent lateral stiffness of the structure was calculated by using threeload distribution forms including inverted triangle distribution load, wind load and earthquake action, and then theinfluences of the structure??s ratio of stiffness to weight and P?Δ effect were obtained. The results show that the structure hasgood lateral stiffness and overall stability performance. MIDAS Gen software was used to analyze the overall buckling of thestructure, which further proves that the structure has good overall stability performance. The critical buckling loads of megacolumns and RCFT middle columns were calculated using elastic buckling method, and the calculated length coefficient wascalculated by Euler Formula.

Keywords:Haikou Twin Towers; overall stability; elastic equivalent lateral stiffness; the ratio of stiffness to weight;calculated length coefficient
