[摘要] 長安萬科中心建筑高度260m，共59層，結(jié)構(gòu)采用不帶加強層的鋼筋混凝土框架-核心筒體系，屬于高度超限建筑，同時存在局部樓板不連續(xù)及局部跨層柱等不規(guī)則項。設(shè)計采用基于性能的抗震設(shè)計方法和合理化的結(jié)構(gòu)布置，充分發(fā)揮體系的抗側(cè)效率，底部采用型鋼混凝土柱和中高區(qū)采用水平加腋梁提高鋼筋混凝土結(jié)構(gòu)體系的延性。分析表明：該結(jié)構(gòu)體系各項相關(guān)參數(shù)滿足規(guī)范要求，結(jié)構(gòu)整體及構(gòu)件的抗震性能均可達到預(yù)期的性能目標。

Abstract：ChanganWanke Center has an architectural height of 322.9m with total 59 stories. The main structural system is reinforced concrete frame-core tube without outriggers and belt members. The tower is out-of-codes high-rise building with a number of structural irregularity indexes, such as the local discontinuous floor and local cross-layer column. Since performance-based seismic design method and rationalization of the structural arrangement were used in this building, lateral efficiency of the system can be given the full play, and using steel reinforced concrete column and horizontal haunched beams can be improved the ductility of the reinforced concrete structure system. The research shows that relevant parameters can meet code requirements, and the seismic performance of whole structure and each structural member can reach the expected objective.
Keywords：reinforced concrete frame-core wall structural system; horizontal haunched beams; performance-based seismic design
