［摘要］矩形鋼管混凝土組合異形柱框架-支撐結(jié)構(gòu)體系對風(fēng)荷載比較敏感，不宜用于80m以上的高層建筑中。滄州福康家園項(xiàng)目25，26層鋼結(jié)構(gòu)住宅高度約為80m，采用矩形鋼管混凝土組合異形柱框架-剪力墻體系，其中4號樓結(jié)構(gòu)高度達(dá)76-4m，該結(jié)構(gòu)為目前采用異形柱技術(shù)的最高建筑。以4號樓為例，通過有限元軟件對其進(jìn)行設(shè)計(jì)計(jì)算，結(jié)果表明各項(xiàng)指標(biāo)均滿足各規(guī)范要求。通過靜力彈塑性分析可知，矩形鋼管混凝土組合異形柱框架-剪力墻體系在罕遇地震作用下的破壞機(jī)制合理，具有較好的抗震性能，滿足相應(yīng)規(guī)范要求。由此可知，新體系具有良好的建筑效果，抗震性能良好，在高層住宅領(lǐng)域應(yīng)用前景廣闊。

Abstract:Special-shaped concrete filled rectangular steel tubular（SCFRT）frame-brace system is sensitive to the wind load，it is not suitable for the building above 80 meters tall. The
steel structure residential buildings with 25, 26 layers of Fukang project about 80 meters adopts the SCFRT frame-shear wall system. The height of 4th tower is 76-4 meters, which is the highest building adopted special-shaped column technology. The finite element analysis software was used to analyze the structure performance of 4th tower. The results show that all indexes meet the code requirements. Through the static elasto\|plastic analysis, the SCFRT frame-shear wall system reflects reasonable damage mechanism and has excellent seismic performance as well as meets the code requirements. The new system has broad prospect with great architectural effect and seismic performance.
Keywords:special-shaped concrete filled rectangular steel tubular; frame-shear wall system; static elasto\|plastic analysis; high-rise steel structure residential building
