［摘要］深圳來福士廣場屬于大型商業(yè)公共建筑，其中A座為部分框支剪力墻結(jié)構(gòu)。由于受建筑功能限制，需在塔樓內(nèi)部設(shè)置電影院，使得結(jié)構(gòu)需在7層進(jìn)行高位轉(zhuǎn)換，且跨度較大，最大跨度達(dá)22m。通過PKPM，ETABS，PERFORM-3D等軟件進(jìn)行結(jié)構(gòu)計算分析，結(jié)果表明，對于此種大跨結(jié)構(gòu)采用斜柱進(jìn)行轉(zhuǎn)換，以減小轉(zhuǎn)換梁跨度的做法是可行的，且減小了對建筑功能的影響。同時針對大跨高位轉(zhuǎn)換也提出了相應(yīng)的加強措施。

Abstract:Raffles Square in Shenzhen is a large commercial public building, including the No. A building with the partially framed shear wall structure. Due to the building function limits, a cinema needs to be set inside the tower, which needs a high-position conversion with the largest span up to 22m at seventh layer of the structure. Programs of PKPM，ETABS and PERFORM-3D were used to conduct calculation and analysis on the structure. Analysis results show that it is feasible using inclined column conversion in such a large span structure to reduce the conversion beam span and reduce the effect on building function. Related strengthening measures were also raised for large-span high-position conversion.
Keywords:Raffles Square in Shenzhen； high-position conversion; out-of-code high-rise structure; dynamic elasto-plastic time-history analysis
