［摘要］由于建筑立面造型的需要，結(jié)構(gòu)在上部樓層需要實現(xiàn)豎向整體內(nèi)收，基礎(chǔ)頂～5層、8～12層、18～22層和28～32層采用斜柱，采用YJK軟件對比分析斜柱方案和轉(zhuǎn)換方案對結(jié)構(gòu)整體指標(biāo)的影響，同時分析斜柱對結(jié)構(gòu)梁板和核心筒的影響。結(jié)果表明，斜柱能夠增加結(jié)構(gòu)的整體剛度，同時對梁板產(chǎn)生拉力，應(yīng)對斜柱起始處梁采取增設(shè)型鋼和板加大配筋等措施保證水平力的傳遞，并應(yīng)加強節(jié)點構(gòu)造，使節(jié)點構(gòu)造滿足節(jié)點后于構(gòu)件破壞。

Abstract:Due to the need of building facade modeling, the structure needs to achieve vertical overall adduction on the upper floor. Inclined columns were used for the foundation top～5 floors, 8 ～12 floors and 28～32 floors. The influence of inclined column scheme and conversion scheme on the overall index of the structure was compared and analyzed by YJK. The analysis results show that the inclined column can increase the overall stiffness of the structure and at the same time produce tension on the beam and plate. Measures such as enhancing the beam with profile steel and using more reinforcement in the slab that located at the beginning of the inclined column should be taken to ensure the transmission of horizontal force，and the node should be strengthened to make the node meet the requirements of the node failure after the component failure.
Keywords:inclined column; beam tension; floor stress; node analysis； frame-corewall structure
