［摘要］框架-核心筒結(jié)構(gòu)樓蓋角部的框架柱與核心筒角部剪力墻之間一般采用斜梁連接，或采用半框架梁間接傳力到剪力墻。成都某超高層塔樓創(chuàng)新性地采用Y形框架梁連接框架柱與核心筒剪力墻，對Y形框架梁的優(yōu)化布置進行了對比分析，并對該超高層建筑進行了基于性能的抗震設(shè)計，重點分析了Y形框架梁的性能水準，進行了結(jié)構(gòu)模型試驗，結(jié)果表明該超高層建筑能達到預設(shè)的性能目標，采用Y形框架梁是一種可行的結(jié)構(gòu)布置方案，可供類似工程參考。

Abstract:In the floor corner of frame-core tube structures, inclined beams are usually used to connect the frame columns with the corner shear walls of the core tube, or semi-frame beams are used to transfer force indirectly to the shear walls. A super high-rise tower in Chengdu innovatively adopts Y-shaped frame beam to connect frame columns with core tube shear wall. The optimal layout of Y-shaped frame beam was compared and analyzed. The performance-based seismic design of the super high-rise building was carried out, with emphasis on the performance level analysis of Y-shaped frame beam. The structural model test was carried out. The results prove that the expected performance target of the super high-rise building can be achieved. The structural layout scheme with Y-shaped frame beam is feasible and can be used as a reference for similar projects.
